3 | * Changes in Quagga 0.99.24 |
4 | ||
5 | User-visible changes: | |
6 | - [pimd] New daemon: pimd provides IPv4 PIM-SSM multicast routing. | |
7 | - [bgpd] New feature: "next-hop-self all" to override nexthop on iBGP route | |
8 | reflector setups. | |
9 | - [bgpd] route-maps have a new action "set ipv6 next-hop peer-address" | |
10 | - [bgpd] route-maps have a new action "set as-path prepend last-as" | |
11 | - [bgpd] Update validity checking (particularly MP-BGP / IPv6 routes) was | |
12 | touched up significantly. Please report possible bugs. | |
13 | - [ripd] New feature: RIP for IPv4 now supports equal-cost multipath (ECMP) | |
14 | - [zebra] Multicast RIB support has been extended. It still is IPv4 only. | |
15 | - [zebra] "no link-detect" is now printed in configurations since it won't | |
16 | be the default anymore soon. To retain current behaviour, re-save your | |
17 | configuration after updating to 0.99.24. | |
18 | ||
19 | Distributor-visible changes: | |
20 | - --enable-pimd is added to enable pimd. It is considered experimental, though | |
21 | unless the distribution target is embedded systems with little flash, there | |
22 | is no reason to not include it in packages. | |
23 | - --disable-ipv6 no longer exists as an option. It's 2015, your C library | |
24 | really needs to have IPv6 support by now. | |
25 | - --disable-netlink no longer exists as an option. It didn't work anyway. | |
26 | - --disable-solaris no longer exists as an option. It only controlled some | |
27 | init scripts. | |
28 | - --enable-isisd is now the default. | |
29 | - mrlg.cgi is no longer included (it was severely outdated). It can be found | |
30 | independently at http://mrlg.op-sec.us/ | |
31 | - build on Linux with the musl C library should now work | |
32 | ||
2c32ee5f DL |
33 | * Changes in Quagga 0.99.23 |
34 | ||
35 | Known issues: | |
36 | - [bgpd] setting an extcommunity in a route map on a route that already has | |
37 | an extcommunity attribute will cause bgpd to crash. This issue will be | |
38 | fixed in a followup minor release. | |
39 | ||
40 | User-visible changes: | |
41 | - [lib] Performance enhancements on hashes and timers. | |
42 | - [bgpd] New feature: iBGP TTL security. | |
43 | - [bgpd] New feature: relaxed bestpath criteria for multipath and improved | |
44 | display of multipath routes in "show ip bgp". Scripts parsing this output | |
45 | may need to be updated. | |
46 | - [bgpd] Multiprotocol peerings over IPv6 now try to find a more appropriate | |
47 | IPv4 nexthop by looking at the interface. | |
48 | - [ospf6d] A large amount of changes has been merged for ospf6d. Careful | |
49 | evaluation prior to deployment is recommended. | |
50 | - [zebra] Recursive route support has been overhauled. Scripts parsing | |
51 | "show ip route" output may need adaptation. | |
52 | - [zebra] IPv6 address management has been improved regarding tentative | |
53 | addresses. This is visible in that a freshly configured address will not | |
54 | immediately be marked as usable. | |
55 | - [*] a lot of bugs have been fixed, please refer to the git log | |
56 | ||

57 | * Changes in Quagga 0.99.22 |
58 | ||
dcab1bb8 CF |
59 | - [bgpd] The semantics of default-originate route-map have changed. |
60 | The route-map is now used to advertise the default route conditionally. | |
61 | The old behaviour which allowed to set attributes on the originated | |
62 | default route is no longer supported. | |
d3c74d21 DL |
63 | - [bgpd] There is now a replace-as option to neighbor ... local-as ... |
64 | no-prepend. For details, refer to the user documentation. | |
65 | - [zebra] An FPM interface has been added. This provides an alternate | |
66 | interface to routing information and is geared at OpenFlow & co. | |
67 | - [snmp] AgentX is now supported; the old smux backend is considered | |
68 | deprecated. ospf6d has also had OSPFV3-MIB added. | |
69 | - [*] several issues with configuration save/load/apply have been fixed, | |
70 | in particular on ospf "max-metric router-lsa administrative" and | |
71 | "distribute-list", bgpd "no neighbor activate", isisd "metric-style", | |
72 | - [*] a lot of bugs have been fixed, please refer to the git log | |
dcab1bb8 | 73 | |
828f235d DL |
74 | * Changes in Quagga 0.99.21 |
75 | ||
76 | - [bgpd] BGP multipath support has been merged | |
77 | - [bgpd] SAFI (Multicast topology) support has been extended to propagate | |
78 | the topology to zebra. | |
79 | - [bgpd] AS path limit functionality has been removed | |
80 | - [babeld] a new routing daemon implementing the BABEL ad-hoc mesh routing | |
81 | protocol has been merged. | |
82 | - [isisd] a major overhaul has been picked up. Please note that isisd is | |
83 | STILL NOT SUITABLE FOR PRODUCTION USE. | |
84 | - [*] a lot of bugs have been fixed, please refer to the git log | |

9c1deac7 | 86 | * Changes in Quagga 0.99.10 |
70856417 | 87 | |
0b2aa3a0 PJ |
88 | - [bgpd] 4-byte AS support added |
89 | - [bgpd] MRT format changes to version 2. Those relying on | |
90 | bgpd MRT table dumps may need to update their tools. | |
311064dd | 91 | - [bgpd] Added new route-map set statement: "as-path exclude" |
13e896ba DO |
92 | - Zebra RIB updates queue has evolved into a multi-level |
93 | structure to address RIB consistency issues. | |
0b2aa3a0 PJ |
94 | |
95 | * Changes in Quagga 0.99.2 | |
96 | ||
cf220d1f | 97 | - [bgpd] Work queues added to bgpd to split up update processing, |
98 | particularly beneficial when a peer session goes down. AS_PATH | |
99 | parsing rewritten to be clearer, more robust and ready for 4-byte. | |
70856417 | 100 | |
cf220d1f | 101 | - [ripd] Simple authentication is no longer the default authentication |
102 | mode for ripd. The default is now no-authentication. Any setups which | |
103 | used simple authentication will probably need to update their | |
104 | configuration manually. | |
105 | ||
106 | - [ospfd] 1s dead-interval with sub-second Hellos feature added. | |
107 | SPF timers now specified in milliseconds, and with adaptive | |
108 | hold-time support. RFC3137 Stub-router support added. Default ABR | |
109 | type is now 'cisco'. | |
110 | ||
111 | - Solaris least privileges support added. | |
70856417 | 112 | |
0c2029e9 | 113 | * Changes in Quagga 0.99.1 |
5e4008f7 | 114 | |
0c2029e9 | 115 | - Zserv is now buffered via threads and non-blocking in most cases for both |
116 | clients and zebra, which should improve responsiveness of daemons when | |
117 | they must send many messages to zebra. | |
5e4008f7 | 118 | |
119 | - 'show thread cpu' now displays both cpu+system and wall-clock time, | |
120 | where getrusage() is available. | |
121 | ||
122 | - Background threads added and workqueue API added, with a | |
123 | 'show work-queues' command. Thread scheduling improved slightly. | |
124 | ||
125 | - Zebra now has a work-queue for RIB processing. See 'show work-queues' in | |
126 | the zebra daemon vty. | |
127 | ||
0c2029e9 | 128 | - Support for interface renaming on Linux netlink systems. |
129 | ||
130 | - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip | |
131 | route-source" command. | |
132 | ||
133 | - Automatic logging of backtraces should daemons crash to assist in | |
134 | diagnosis. See the documentation for more information on configuring | |
135 | logging correctly, and set --enable-gcc-rdynamic if compiling with gcc. | |
136 | ||
de4a643f | 137 | * Changes in Quagga 0.98.0 |
138 | ||
73a7dea3 | 139 | - Logging facilities upgraded. One can now specify a severity level |
140 | for each logging destination. And a new "show logging" command gives | |
141 | thorough information on the current logging system configuration. | |
142 | ||
8035e9f0 | 143 | - Watchquagga daemon added. This is not well tested yet. Please try |
144 | monitor mode first before enabling restart features. It is important | |
145 | to make sure that the various timers are configured with appropriate | |
146 | values for your site. | |
147 | ||
14c17fd8 | 148 | - BGP route-server support added. See the texinfo documentation. |
149 | ||
de4a643f | 150 | - OSPF API initialisation is disabled by default even if compiled in. You |
151 | can enable it with -a/--apiserver command line switch. | |
8694b9f6 | 152 | |
9a3805e0 | 153 | - "write-config integrated" vtysh command replaced with "service |
154 | integrated-vtysh-config" command. | |
155 | ||
156 | - Router id is now handled by zebra daemon and all daemons receive changes | |
157 | from it. Router id can be overriden in daemons' configurations of course. | |
158 | To fix common router id in zebra daemon you can either install non-127 | |
159 | address on loopback or use "router-id x.x.x.x" command. | |
160 | ||
161 | - "secondary" keyword is removed from ip address configuration. All | |
162 | supported OS'es have their own vision what's secondary address and | |
163 | how to handle it. | |
164 | ||
3e0b3a56 | 165 | - Zebra no longer enables forwarding by default. If you rely on zebra to |
166 | enable forwarding make sure to add '<ip|ip6> forwarding' statements | |
167 | to your zebra configuration file. | |
168 | ||
79683de8 | 169 | - All libraries are built and used shared, on platforms where libtool |
170 | supports shared libraries. | |
171 | ||
8694b9f6 | 172 | - Router advertisement syntax is changed. In usual cases (if you didn't do |
173 | any fancy stuff) it's enough to change lines in configuration from: | |
174 | "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link" | |
175 | to: | |
176 | "ipv6 nd prefix X:X:X:X::/X" | |
177 | ||
178 | All router advertisement options are documented in texi documentation. | |
179 | ||
180 | - --enable-nssa configure switch is removed. NSSA support is stable enough. | |
181 | ||
182 | - Daemons don't look at current directory for config file any more. | |
183 | ||
af273652 | 184 | * Changes in Quagga 0.96.5 |
185 | ||
186 | - include files are installed in $(prefix)/include/quagga. Programs | |
187 | building against these includes should -I$(prefix)/include and e.g. | |
188 | #include <quagga/routemap.h> | |
189 | ||
190 | - New option --enable-exampledir puts example files in a separate | |
191 | directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules | |
192 | compliance. | |
193 | ||
aa593d5e | 194 | - New configure options --enable-configfile-mask and |
195 | --enable-logfile-mask to set umask values for config and log | |
196 | values. Masks default to 0600, matching previous behavior. | |
197 | ||
9e867fe6 | 198 | - Import current CVS isisd from SourceForge, then merge it with |
199 | the Quagga's Framework. | |
200 | ||
291eb0ec | 201 | * Changes in Quagga 0.96.4 |
202 | ||
203 | - Further fixes to ospfd, some relating to the PtP revert. Interface | |
204 | lookups should be a lot more robust now. | |
205 | ||
206 | - Fix for a remote triggerable crash in vty layer. | |
207 | ||
208 | - Improvements to ripd, and addition of split horizon support. | |
209 | ||
210 | - Improved bgpd table support, now dumps at time of day intervals rather | |
211 | than time from startup intervals. Much improved support for IPv6 table | |
212 | dumps. show commands for views improved. | |
213 | ||
5ae016ee | 214 | * Changes in Quagga 0.96.3 |
215 | ||
216 | - revert the 'generic PtP' patch. Means Quagga will no longer work with | |
217 | FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs | |
218 | which the PtP patch introduced. | |
219 | ||
9491975e | 220 | * Changes in Quagga 0.96.2 |
221 | ||
222 | - Fix crash in ospfd | |
223 | ||

229 | ||
230 | - Privilege support, daemons now run with the minimal privileges needed, see | |
231 | the documentation for details. | |
232 | ||
233 | - NSSA ABR support in ospfd. | |
234 | ||
235 | - OSPF-API support merged in. | |
236 | ||
237 | - 6WIND patch merged in. | |

250 | Inc. | |
251 | ||
252 | * Chages in ospf6d | |
253 | ||
254 | ** Many bugs are fixed. | |

257 | ||
258 | * Changes in bgpd | |
259 | ||
260 | ** Fix "^$" community list bug. | |
261 | ||
262 | ** Below command's Address Family specific configurations are added | |
263 | ||

266 | route-server-client | |
267 | soft-reconfiguration inbound | |
268 | ||
269 | * Changes in zebra | |
270 | ||
271 | ** Treat kernel type routes as EGP routes. | |
6b0655a2 | 272 | |
718e3744 | 273 | * Changes in zebra-0.92 |
274 | ||
275 | ** Overall security is improved. Default umask is 0077. | |
276 | ||
277 | * Changes in ripd | |
278 | ||
279 | ** If output interface is in simple password authentication mode, | |
280 | substruct one from rtemax. | |
281 | ||
282 | * Changes in bgpd | |
283 | ||
284 | ** IPv4 multicast and IPv6 unicast configuration is changed to so | |
285 | called new config. All of AFI and SAFI specific configuration is | |
286 | moved to "address-family" node. When you have many IPv6 only | |
287 | configuration, you will see many "no neighbor X:X::X:X activate" line | |
288 | in your configuration to disable IPv4 unicast NLRI exchange. In that | |
289 | case please use "no bgp default ipv4-unicast" command to suppress the | |
290 | output. Until zebra-0.93, old config is still left for compatibility. | |

447 | zebra. New RIB has many new features and fixed some bugs which exist | |
448 | in old RIB code. | |
449 | ||
450 | *** Static route with distance value | |
451 | ||
452 | Static route can be specified with administrative distance. The | |
453 | distance value 255 means it is not installed into the kernel. | |
454 | Default value of distance for static route is 1. | |
455 | ||
456 | ip route A.B.C.D/M A.B.C.D <1-255> | |
457 | ip route A.B.C.D/M IFNAME <1-255> | |
458 | ||
459 | If the least distance value's route's nexthop are unreachable, | |
460 | select the least distance value route which has reachable nexthop is | |
461 | selected. | |
462 | ||
463 | ip route 0.0.0.0/0 10.0.0.1 | |
464 | ip route 0.0.0.0/0 11.0.0.1 2 | |
465 | ||
466 | In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is | |
467 | reachable. The route with nexthop 11.0.0.1 will be installed into | |
468 | forwarding table. | |
469 | ||
470 | zebra> show ip route | |
471 | S>* 0.0.0.0/0 [2/0] via 11.0.0.1 | |
472 | S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive | |
473 | ||
474 | If the nexthop is unreachable "inactive" is displayed. You can | |
475 | specify any string to IFNAME. There is no need of the interface is | |
476 | there when you configure the route. | |
477 | ||
478 | ip route 1.1.1.1/32 ppp0 | |
479 | ||
480 | When ppp0 comes up, the route is installed properly. | |
481 | ||
482 | *** Multiple nexthop routes for one prefix | |
483 | ||
484 | Multiple nexthop routes can be specified for one prefix. Even the | |
485 | kernel support only one nexthop for one prefix user can configure | |
486 | multiple nexthop. | |
487 | ||
488 | When you configure routes like below, prefix 10.0.0.1 has three | |
489 | nexthop. | |
490 | ||
491 | ip route 10.0.0.1/32 10.0.0.2 | |
492 | ip route 10.0.0.1/32 10.0.0.3 | |
493 | ip route 10.0.0.1/32 eth0 | |
494 | ||
495 | If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0 | |
496 | is reachable, then the last route is installed into the kernel. | |
497 | ||
498 | zebra> show ip route | |
499 | S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive | |
500 | via 10.0.0.3 inactive | |
501 | * is directly connected, eth0 | |
502 | ||
503 | '*' means this nexthop is installed into the kernel. | |
504 | ||
505 | *** Multipath (more than one nexthop for one prefix) can be installed into the kernel. | |
506 | ||
507 | When the kernel support multipath, zebra can install multipath | |
508 | routes into the kernel. Before doing that please make it sure that | |
509 | setting --enable-multipath=ARG to configure script. ARG must be digit | |
510 | value. When specify 0 to ARG, there is no limitation of the number | |
511 | of the multipath. Currently only GNU/Linux with netlink interface is | |
512 | supported. | |
513 | ||
514 | ip route 10.0.0.1/32 10.0.0.2 | |
515 | ip route 10.0.0.1/32 10.0.0.3 | |
516 | ip route 10.0.0.1/32 eth0 | |
517 | ||
518 | zebra> show ip route | |
519 | S>* 10.0.0.1/32 [1/0] via 10.0.0.2 | |
520 | * via 10.0.0.3 | |
521 | is directly connected, eth0 | |
522 | ||
523 | *** Kernel message delete installed route. | |
524 | ||
525 | After zebra install static or dynamic route into the kernel. | |
526 | ||
527 | R>* 0.0.0.0/0 [120/3] via 10.0.0.1 | |
528 | ||
529 | If you delete this route outside zebra, old zebra does not reinstall | |
530 | route again. Now the route is re-processed and properly reinstall the | |
531 | static or dynamic route into the kernel. | |
532 | ||
533 | ** GNU/Linux netlink socket handling is improved to fix race condition | |
534 | between kernel message and user command responce. | |
535 | ||
536 | * Changes in bgpd | |
537 | ||
538 | ** Add show neighbor's routes command. | |

542 | "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes" | |
543 | "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes" | |
544 | ||
545 | ** BGP passive peer support problem is fixed. | |
546 | ||
547 | ** Redistributed IGP nexthop is passed to BGP nexthop. | |
548 | ||
549 | ** On multiaccess media, if the nexthop is reachable nexthop is passed | |
550 | as it is. | |
551 | ||
552 | ** Remove zebra-0.88 compatibility commands. | |
553 | ||
554 | "match ip prefix-list WORD" | |
555 | "match ipv6 prefix-list WORD" | |
556 | ||
557 | Instead of above please use below commands. | |
558 | ||
559 | "match ip address prefix-list WORD" | |
560 | "match ipv6 address prefix-list WORD" | |
561 | ||
562 | ** Fix bug of holdtimer is not reset when bgp cleared. | |
563 | ||

565 | ||
566 | ** Change "match ip next-hop" argument from IP address to access-list | |
567 | name. | |
568 | ||
569 | ** When "bgp enforce-first-as" is enabled, check EBGP peer's update | |
570 | has it's AS number in the first AS number in AS sequence. | |
571 | ||
572 | ** New route-map command "set community-delete COMMUNITY-LIST" is | |
573 | added. Community matched the CoMMUNITY-LIST is removed from the | |
574 | community. | |
575 | ||
576 | ** BGP-MIB implementation is finished. | |
577 | ||
578 | ** When BGP connection comes from unconfigured IP address, close | |
579 | socket immediately. | |
580 | ||
581 | ** Do not compare router ID when the routes comes from EBGP peer. | |
582 | When originator ID is same, take shorter cluster-list route. If | |
583 | cluster-list is same take smaller IP address neighbor's route. | |
584 | ||
585 | ** Add "bgp bestpath as-path ignore" command. When this option is | |
586 | set, do not concider AS path length when route selection. | |
587 | ||
588 | ** Add "bgp bestpath compare-routerid". When this option is set, | |
589 | compare router ID when the routes comes from EBGP peer. | |
590 | ||
591 | ** Add "bgp deterministic-med" process. | |
592 | ||
593 | ** BGP flap dampening feature is added. | |
594 | ||

606 | ||
607 | ** Memory leak related classfull network generation is fixed. | |
608 | ||
609 | ** When a route is in garbage collection process (invalid with metric | |
610 | 16) and a router receives the same route with valid metric then route | |
611 | was not installed into zebra rib, but only into ripd rib. Moreover , | |
612 | it will never get into zebra rib, because ripd wrongly assumes it's | |
613 | already there. | |
614 | ||
615 | * Change in ospfd | |
616 | ||
617 | ** Fix bug of refreshing default route. | |

629 | with interface priority 0). It's router LSA does not contain the link | |
630 | information about this network. | |
631 | ||
632 | ** When you change a priority of interface from/to 0 | |
633 | ISM_NeighborChange event should be scheduled in order to elect new | |
634 | DR/BDR on the network. | |
635 | ||
636 | ** When we add some LSA into retransmit list we need to check whether | |
637 | the present old LSA in retransmit list is not more recent than the new | |
638 | one. | |
639 | ||
640 | ** In states Loading and Full the slave must resend its last Database | |
641 | Description packet in response to duplicate Database Description | |
642 | packets received from the master. For this reason the slave must wait | |
643 | RouterDeadInterval seconds before freeing the last Database | |
644 | Description packet. Reception of a Database Description packet from | |
645 | the master after this interval will generate a SeqNumberMismatch | |
646 | neighbor event. RFC2328 Section 10.8 | |
647 | ||
648 | ** Virtual link can not configured in stub area. | |
649 | ||

1161 | * Changes in lib | |
1162 | ||
1163 | ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada | |
1164 | <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address, | |
1165 | "X:X::X:X/M" for IPv6 prefix. You can use it like this. | |
1166 | ||
1167 | DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>") | |
1168 | ||
1169 | ** VTY configuration is locked during configuration. This is for | |
1170 | avoiding unconditional crush from two terminals modify the | |
1171 | configuration at the same time. "who" command shows which termnal | |
1172 | lock the configuration. VTY which has '*' character at the head of | |
1173 | line is locking the configuration. | |
1174 | ||
1175 | ** Old logging functions are removed. Functions like | |
1176 | log_open,log_close,openlog are deleted. Instead of that please use | |
1177 | zlog_* functions. zvlog_* used in ospf6d are deleted also. | |
1178 | ||
1179 | ** "terminal monitor" command is added. "no terminal monitor" is for | |

1193 | without specifying AS number. | |
1194 | ||
1195 | ** "no neighbor ebgp-multihop" command is added. | |
1196 | ||
1197 | ** "no neighbor port PORT" command is added. | |
1198 | ||
1199 | ** To conform RFC1771, "neighbor PEER send-community" is default | |

1201 | please specify "no neighbor PEER send-community" to the peer. | |
1202 | ||
1203 | ** "neighbor maximum-prefix NUMBER" command is added. | |
1204 | ||
1205 | ** Multi-protocol extention NLRI is proceeded only when the peer is | |
1206 | configured proper Address Family and Subsequent Address Family. If | |
1207 | not, those NLRI are simply ignored. | |
1208 | ||
1209 | ** Aggregate-address support is improved. Currently below commands | |
1210 | works. | |
1211 | ||
1212 | "aggregate-address" | |
1213 | "aggregate-address summary-only" | |
1214 | "no aggregate-address" | |

718e3744 | 1238 | * Changes in zebra-0.83 |
1239 | ||
1240 | * bgpd | |
1241 | ||
1242 | ** Serious bug fix about fetching global and link-local address at the | |
1243 | same time. Due to this bug, corrupted IPv6 prefix is generated. If | |
1244 | you uses bgpd for BGP-4+ please update to this version. The bug is | |
1245 | introduced in zebra-0.82. | |
1246 | ||
1247 | ** When bgpd send Notify message, don't use thread manager. It is now | |

1252 | ** Solaris 2.6 support is added by Michael Handler | |
1253 | <handler@sub-rosa.com>. | |
1254 | ||
1255 | ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>. | |
1256 | Please specify --enable-mbgp to configure script. This option will be | |
1257 | removed in the future and MBGP support will be default. | |
1258 | ||
1259 | * Changes in zebra | |
1260 | ||
1261 | ** When interface goes down, withdraw connected routes from routing | |
1262 | table. When interface goes up, restore the routes to the routing | |
1263 | table. | |
1264 | ||
1265 | ** `show interface' show interface's statistics on Linux and BSD with | |
1266 | routing socket. | |
1267 | ||
1268 | ** Now zebra can get MTU value on BSDI/OS. | |
1269 | ||
1270 | * Changes in bgpd | |
1271 | ||
1272 | ** Add capability option support based upon | |
1273 | draft-ietf-idr-bgp4-cap-neg-04.txt. | |
1274 | ||
1275 | ** Add `show ipv6 bgp prefix-list' command. | |
1276 | ||
1277 | ** Check self AS appeared in received routes. | |

6b0655a2 | 1300 | |
718e3744 | 1301 | * Changes in zebra-0.81 |
1302 | ||
1303 | ** SNMP support is disabled in default.--enable-snmp option is added | |
1304 | to configure script. | |
1305 | ||
1306 | * Changes in bgpd | |
1307 | ||
1308 | ** Fix FSM bug which introduced in zebra-0.80. | |
6b0655a2 | 1309 | |
718e3744 | 1310 | * Changes in zebra-0.80 |
1311 | ||
1312 | * access-list | |
1313 | ||
1314 | New access-list name space `ipv6 access-list' is added. At the same | |
1315 | time, `access-list' statemant only accepts IPv4 prefix. Please be | |
1316 | careful if you use IPv6 filtering. You will need to change your | |
1317 | configuration. For IPv6 filtering please use `ipv6 access-list'. | |
1318 | ||
1319 | As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6 | |
1320 | filtering. | |
1321 | ||
1322 | ! zebra-0.7x | |
1323 | access-list DML-net permit 203.181.89.0/24 | |
1324 | access-list DML-net permit 3ffe:506::0/32 | |
1325 | access-list DML-net deny any | |
1326 | ! | |
1327 | ||
1328 | Above configuration is not valid for zebra-08x. Please add `ipv6' | |
1329 | before 'access-list' when you configure IPv6 filtering. | |
1330 | ||
1331 | ! zebra-0.8x | |
1332 | access-list DML-net permit 203.181.89.0/24 | |
1333 | access-list DML-net deny any | |
1334 | ! | |
1335 | ipv6 access-list DML-net permit 3ffe:506::0/32 | |
1336 | ipv6 access-list DML-net deny any | |
1337 | ! | |
1338 | ||
1339 | * prefix-list | |
1340 | ||
1341 | And also new prefix-list name space `ipv6 prefix-list' is added. It | |
1342 | is the same as the change of `access-list'. `ip prefix-list' now only | |
1343 | accept IPv4 prefix. It was source of confusion that `ip prefix-list' | |
1344 | can be used both IPv4 and IPv6 filtering. Now name space is separated | |
1345 | to clear the meaning of the filter. | |
1346 | ||
1347 | If you use `ip prefix-list' for IPv6 filtering, please change the | |
1348 | stetement. | |
1349 | ||
1350 | ! zebra-0.7x | |
1351 | ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24 | |
1352 | ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28 | |
1353 | ip prefix-list 6bone-filter seq 12 deny 3ffe::/16 | |
1354 | ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16 | |
1355 | ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35 | |
1356 | ip prefix-list 6bone-filter seq 30 deny any | |
1357 | ! | |
1358 | ||
1359 | Now user can explicitly configure it as IPv6 prefix-list. | |
1360 | ||
1361 | ! zebra-0.8x | |
1362 | ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24 | |
1363 | ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28 | |
1364 | ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16 | |
1365 | ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16 | |
1366 | ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35 | |
1367 | ipv6 prefix-list 6bone-filter seq 30 deny any | |
1368 | ! | |
1369 | ||
1370 | * RIP configuration | |
1371 | ||
1372 | If you want to filter only default route (0.0.0.0/0) and permit other | |
1373 | routes, it was hard to do that. Now `ip prefix-list' can be used for | |
1374 | RIP route filtering. | |
1375 | ||
1376 | New statement: | |
1377 | ||
1378 | `distribute-list prefix PLIST_NAME (in|out) IFNAME' | |
1379 | ||
1380 | is added to ripd. So you can configure on eth0 interface accept all | |
1381 | routes other than default routes. | |
1382 | ||
1383 | ! | |
1384 | router rip | |
1385 | distribute-list prefix filter-default in eth0 | |
1386 | ! | |
1387 | ip prefix-list filter-default deny 0.0.0.0/0 le 0 | |
1388 | ip prefix-list filter-default permit any | |
1389 | ! | |
1390 | ||
1391 | * RIPng configuration | |
1392 | ||
1393 | Same change is done for ripngd. You can use `ipv6 prefix-list' for | |
1394 | filtering. | |
1395 | ||
1396 | ! | |
1397 | router ripng | |
1398 | distribute-list prefix filter-default in eth0 | |
1399 | ! | |
1400 | ipv6 prefix-list filter-default deny ::/0 le 0 | |
1401 | ipv6 prefix-list filter-default permit any | |
1402 | ! | |
1403 | ||
1404 | * BGP configuration | |
1405 | ||
1406 | So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is | |
1407 | done with traditional IPv4 peering statement like blow. | |
1408 | ||
1409 | ! | |
1410 | router bgp 7675 | |
1411 | neighbor 3ffe:506::1 remote-as 2500 | |
1412 | neighbor 3ffe:506::1 prefix-list 6bone-filter out | |
1413 | ! | |
1414 | ||
1415 | For separating configuration IPv4 and IPv6, and for retaining Cisco | |
1416 | configuration compatibility, now IPv6 configuration is done by IPv6 | |
1417 | specific statement. IPv6 BGP configuration is done by statement which | |
1418 | start from `ipv6 bgp'. | |
1419 | ||
1420 | ! | |
1421 | router bgp 7675 | |
1422 | ! | |
1423 | ipv6 bgp neighbor 3ffe:506::1 remote-as 2500 | |
1424 | ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out | |
1425 | ! | |
1426 | ||
1427 | At the same time some IPv6 specific commands are deleted from IPv4 | |
1428 | configuration. | |
1429 | ||
1430 | o redistribute ripng | |
1431 | o redistribute ospf6 | |
1432 | o neighbor PEER version BGP_VERSION | |
1433 | o neighbor PEER interface IFNAME | |
1434 | ||
1435 | Those commands are only accepted as like below. | |
1436 | ||
1437 | o ipv6 bgp redistribute ripng | |
1438 | o ipv6 bgp redistribute ospf6 | |
1439 | o ipv6 bgp neighbor PEER version BGP_VERSION | |
1440 | o ipv6 bgp neighbor PEER interface IFNAME | |
1441 | ||
1442 | And below new commands are added. | |
1443 | ||
1444 | o ipv6 bgp network IPV6_PREFIX | |
1445 | o ipv6 bgp redistribute static | |
1446 | o ipv6 bgp redistribute connected | |
1447 | o ipv6 bgp neighbor PEER remote-as <1-65535> [passive] | |
1448 | o ipv6 bgp neighbor PEER ebgp-multihop [TTL] | |
1449 | o ipv6 bgp neighbor PEER description DESCRIPTION | |
1450 | o ipv6 bgp neighbor PEER shutdown | |
1451 | o ipv6 bgp neighbor PEER route-reflector-client | |
1452 | o ipv6 bgp neighbor PEER update-source IFNAME | |
1453 | o ipv6 bgp neighbor PEER next-hop-self | |
1454 | o ipv6 bgp neighbor PEER timers holdtime <0-65535> | |
1455 | o ipv6 bgp neighbor PEER timers keepalive <0-65535> | |
1456 | o ipv6 bgp neighbor PEER send-community | |
1457 | o ipv6 bgp neighbor PEER weight <0-65535> | |
1458 | o ipv6 bgp neighbor PEER default-originate | |
1459 | o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out) | |
1460 | o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out) | |
1461 | o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out) | |
1462 | o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out) | |
1463 | ||
1464 | And some utility commands are introduced. | |
1465 | ||
1466 | o clear ipv6 bgp [PEER] | |
1467 | o show ipv6 bgp neighbors [PEER] | |
1468 | o show ipv6 bgp summary | |
1469 | ||
1470 | I hope these changes are easy to understand for current Zebra users... | |
1471 | ||
1472 | * To restrict connection to VTY interface. | |
1473 | ||
1474 | It used to be both IPv4 and IPv6 filter can be specified with one | |
1475 | access-list. Then the access-list can be appried to VTY interface | |
1476 | with `access-class' stetement in `line vty' node. Below is example in | |
1477 | zebra-0.7x. | |
1478 | ||
1479 | ! | |
1480 | access-list local-only permit 127.0.0.1/32 | |
1481 | access-list local-only permit ::1/128 | |
1482 | access-list local-only deny any | |
1483 | ! | |
1484 | line vty | |
1485 | access-class local-only | |
1486 | ! | |
1487 | ||
1488 | Now IPv4 and IPv6 filter have each name space. It is not possible to | |
1489 | specify IPv4 and IPv6 filter with one access-list. For setting IPv6 | |
1490 | access-list in `line vty', `ipv6 access-class' statement is | |
1491 | introduced. Let me show the configuration in zebra-0.8x. | |
1492 | ||
1493 | ! | |
1494 | access-list local-only permit 127.0.0.1/32 | |
1495 | access-list local-only deny any | |
1496 | ! | |
1497 | ipv6 access-list local-only permit ::1/128 | |
1498 | ipv6 access-list local-only dny any | |
1499 | ! | |
1500 | line vty | |
1501 | access-class local-only | |
1502 | ipv6 access-class local-only | |
1503 | ! | |
1504 | ||
1505 | * route-map | |
1506 | ||
1507 | New IPv6 related route-map match commands are added. | |
1508 | ||
1509 | o match ipv6 address | |
1510 | o match ipv6 next-hop | |
1511 | ||
1512 | Please change your configuration if you use IP match statement for | |
1513 | IPv6 route. | |
1514 | ||
1515 | zebra-0.7x config | |
1516 | ================= | |
1517 | ! | |
1518 | access-list all permit any | |
1519 | ! | |
1520 | route-map set-nexthop permit 10 | |
1521 | match ip address all | |
1522 | set ipv6 next-hop global 3ffe:506::1 | |
1523 | set ipv6 next-hop local fe80::cbb5:591a | |
1524 | ! | |
1525 | ||
1526 | zebra-0.8x config | |
1527 | ================= | |
1528 | ! | |
1529 | ipv6 access-list all permit any | |
1530 | ! | |
1531 | route-map set-nexthop permit 10 | |
1532 | match ipv6 address all | |
1533 | set ipv6 next-hop global 3ffe:506::1 | |
1534 | set ipv6 next-hop local fe80::cbb5:591a | |
1535 | ! | |
1536 | ||
1537 | * zebra connection | |
1538 | ||
1539 | Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon | |
1540 | when the connection fail. Those daemons try to connect zebra every 10 | |
1541 | seconds first three trial, then the interval changed to 60 seconds. | |
1542 | After all, if ten connections are fail, protocol daemon give up the | |
1543 | connection to the zebra daemon. | |
1544 | ||
1545 | * SNMP support (is not yet finished) | |
1546 | ||
1547 | Zebra uses SMUX protocol (RFC1227) for making communication with SNMP | |
1548 | agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1 | |
1549 | and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be | |
1550 | compiled with ucd-snmp-3.6.2. | |
1551 | ||
1552 | After applying the patch to ucd-snmp-4.0.1, please configure it with | |
1553 | SMUX module. | |
1554 | ||
1555 | % configure --with-mib-modules=smux | |
1556 | ||
1557 | After compile & install ucd-snmp-4.0.1, you will need to configure | |
1558 | smuxpeer. I'm now using below configuration. | |
1559 | ||
1560 | /usr/local/share/snmp/snmpd.conf | |
1561 | ================================ | |
1562 | smuxpeer 1.3.6.1.6.3.1 test | |
1563 | ||
1564 | Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard | |
1565 | coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP. | |
1566 | ||
1567 | * HUP signal treatment | |
1568 | ||
1569 | From zebra-0.80, ripd will reload it's configuration file when ripd | |
1570 | receives HUP signal. Other daemon such as bgpd, ospfd will support | |
1571 | HUP signal treatment soon. | |
