3 | * Changes in Quagga 0.99.23 |
4 | ||
5 | Known issues: | |
6 | - [bgpd] setting an extcommunity in a route map on a route that already has | |
7 | an extcommunity attribute will cause bgpd to crash. This issue will be | |
8 | fixed in a followup minor release. | |
9 | ||
10 | User-visible changes: | |
11 | - [lib] Performance enhancements on hashes and timers. | |
12 | - [bgpd] New feature: iBGP TTL security. | |
13 | - [bgpd] New feature: relaxed bestpath criteria for multipath and improved | |
14 | display of multipath routes in "show ip bgp". Scripts parsing this output | |
15 | may need to be updated. | |
16 | - [bgpd] Multiprotocol peerings over IPv6 now try to find a more appropriate | |
17 | IPv4 nexthop by looking at the interface. | |
18 | - [ospf6d] A large amount of changes has been merged for ospf6d. Careful | |
19 | evaluation prior to deployment is recommended. | |
20 | - [zebra] Recursive route support has been overhauled. Scripts parsing | |
21 | "show ip route" output may need adaptation. | |
22 | - [zebra] IPv6 address management has been improved regarding tentative | |
23 | addresses. This is visible in that a freshly configured address will not | |
24 | immediately be marked as usable. | |
25 | - [*] a lot of bugs have been fixed, please refer to the git log | |

dcab1bb8 CF |
29 | - [bgpd] The semantics of default-originate route-map have changed. |
30 | The route-map is now used to advertise the default route conditionally. | |
31 | The old behaviour which allowed to set attributes on the originated | |
32 | default route is no longer supported. | |
d3c74d21 DL |
33 | - [bgpd] There is now a replace-as option to neighbor ... local-as ... |
34 | no-prepend. For details, refer to the user documentation. | |
35 | - [zebra] An FPM interface has been added. This provides an alternate | |
36 | interface to routing information and is geared at OpenFlow & co. | |
37 | - [snmp] AgentX is now supported; the old smux backend is considered | |
38 | deprecated. ospf6d has also had OSPFV3-MIB added. | |
39 | - [*] several issues with configuration save/load/apply have been fixed, | |
40 | in particular on ospf "max-metric router-lsa administrative" and | |
41 | "distribute-list", bgpd "no neighbor activate", isisd "metric-style", | |
42 | - [*] a lot of bugs have been fixed, please refer to the git log | |

828f235d DL |
44 | * Changes in Quagga 0.99.21 |
45 | ||
46 | - [bgpd] BGP multipath support has been merged | |
47 | - [bgpd] SAFI (Multicast topology) support has been extended to propagate | |
48 | the topology to zebra. | |
49 | - [bgpd] AS path limit functionality has been removed | |
50 | - [babeld] a new routing daemon implementing the BABEL ad-hoc mesh routing | |
51 | protocol has been merged. | |
52 | - [isisd] a major overhaul has been picked up. Please note that isisd is | |
53 | STILL NOT SUITABLE FOR PRODUCTION USE. | |
54 | - [*] a lot of bugs have been fixed, please refer to the git log | |

9c1deac7 | 56 | * Changes in Quagga 0.99.10 |
70856417 | 57 | |
0b2aa3a0 PJ |
58 | - [bgpd] 4-byte AS support added |
59 | - [bgpd] MRT format changes to version 2. Those relying on | |
60 | bgpd MRT table dumps may need to update their tools. | |
311064dd | 61 | - [bgpd] Added new route-map set statement: "as-path exclude" |
13e896ba DO |
62 | - Zebra RIB updates queue has evolved into a multi-level |
63 | structure to address RIB consistency issues. | |
0b2aa3a0 PJ |
64 | |
65 | * Changes in Quagga 0.99.2 | |
66 | ||
cf220d1f | 67 | - [bgpd] Work queues added to bgpd to split up update processing, |
68 | particularly beneficial when a peer session goes down. AS_PATH | |
69 | parsing rewritten to be clearer, more robust and ready for 4-byte. | |
70856417 | 70 | |
cf220d1f | 71 | - [ripd] Simple authentication is no longer the default authentication |
72 | mode for ripd. The default is now no-authentication. Any setups which | |
73 | used simple authentication will probably need to update their | |
74 | configuration manually. | |
75 | ||
76 | - [ospfd] 1s dead-interval with sub-second Hellos feature added. | |
77 | SPF timers now specified in milliseconds, and with adaptive | |
78 | hold-time support. RFC3137 Stub-router support added. Default ABR | |
79 | type is now 'cisco'. | |
80 | ||
81 | - Solaris least privileges support added. | |
70856417 | 82 | |
0c2029e9 | 83 | * Changes in Quagga 0.99.1 |
5e4008f7 | 84 | |
0c2029e9 | 85 | - Zserv is now buffered via threads and non-blocking in most cases for both |
86 | clients and zebra, which should improve responsiveness of daemons when | |
87 | they must send many messages to zebra. | |
5e4008f7 | 88 | |
89 | - 'show thread cpu' now displays both cpu+system and wall-clock time, | |
90 | where getrusage() is available. | |
91 | ||
92 | - Background threads added and workqueue API added, with a | |
93 | 'show work-queues' command. Thread scheduling improved slightly. | |
94 | ||
95 | - Zebra now has a work-queue for RIB processing. See 'show work-queues' in | |
96 | the zebra daemon vty. | |
97 | ||
0c2029e9 | 98 | - Support for interface renaming on Linux netlink systems. |
99 | ||
100 | - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip | |
101 | route-source" command. | |
102 | ||
103 | - Automatic logging of backtraces should daemons crash to assist in | |
104 | diagnosis. See the documentation for more information on configuring | |
105 | logging correctly, and set --enable-gcc-rdynamic if compiling with gcc. | |
106 | ||
de4a643f | 107 | * Changes in Quagga 0.98.0 |
108 | ||
73a7dea3 | 109 | - Logging facilities upgraded. One can now specify a severity level |
110 | for each logging destination. And a new "show logging" command gives | |
111 | thorough information on the current logging system configuration. | |
112 | ||
8035e9f0 | 113 | - Watchquagga daemon added. This is not well tested yet. Please try |
114 | monitor mode first before enabling restart features. It is important | |
115 | to make sure that the various timers are configured with appropriate | |
116 | values for your site. | |
117 | ||
14c17fd8 | 118 | - BGP route-server support added. See the texinfo documentation. |
119 | ||
de4a643f | 120 | - OSPF API initialisation is disabled by default even if compiled in. You |
121 | can enable it with -a/--apiserver command line switch. | |
8694b9f6 | 122 | |
9a3805e0 | 123 | - "write-config integrated" vtysh command replaced with "service |
124 | integrated-vtysh-config" command. | |
125 | ||
126 | - Router id is now handled by zebra daemon and all daemons receive changes | |
127 | from it. Router id can be overriden in daemons' configurations of course. | |
128 | To fix common router id in zebra daemon you can either install non-127 | |
129 | address on loopback or use "router-id x.x.x.x" command. | |
130 | ||
131 | - "secondary" keyword is removed from ip address configuration. All | |
132 | supported OS'es have their own vision what's secondary address and | |
133 | how to handle it. | |
134 | ||
3e0b3a56 | 135 | - Zebra no longer enables forwarding by default. If you rely on zebra to |
136 | enable forwarding make sure to add '<ip|ip6> forwarding' statements | |
137 | to your zebra configuration file. | |
138 | ||
79683de8 | 139 | - All libraries are built and used shared, on platforms where libtool |
140 | supports shared libraries. | |
141 | ||
8694b9f6 | 142 | - Router advertisement syntax is changed. In usual cases (if you didn't do |
143 | any fancy stuff) it's enough to change lines in configuration from: | |
144 | "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link" | |
145 | to: | |
146 | "ipv6 nd prefix X:X:X:X::/X" | |
147 | ||
148 | All router advertisement options are documented in texi documentation. | |
149 | ||
150 | - --enable-nssa configure switch is removed. NSSA support is stable enough. | |
151 | ||
152 | - Daemons don't look at current directory for config file any more. | |
153 | ||
af273652 | 154 | * Changes in Quagga 0.96.5 |
155 | ||
156 | - include files are installed in $(prefix)/include/quagga. Programs | |
157 | building against these includes should -I$(prefix)/include and e.g. | |
158 | #include <quagga/routemap.h> | |
159 | ||
160 | - New option --enable-exampledir puts example files in a separate | |
161 | directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules | |
162 | compliance. | |
163 | ||
aa593d5e | 164 | - New configure options --enable-configfile-mask and |
165 | --enable-logfile-mask to set umask values for config and log | |
166 | values. Masks default to 0600, matching previous behavior. | |
167 | ||
9e867fe6 | 168 | - Import current CVS isisd from SourceForge, then merge it with |
169 | the Quagga's Framework. | |
170 | ||
291eb0ec | 171 | * Changes in Quagga 0.96.4 |
172 | ||
173 | - Further fixes to ospfd, some relating to the PtP revert. Interface | |
174 | lookups should be a lot more robust now. | |
175 | ||
176 | - Fix for a remote triggerable crash in vty layer. | |
177 | ||
178 | - Improvements to ripd, and addition of split horizon support. | |
179 | ||
180 | - Improved bgpd table support, now dumps at time of day intervals rather | |
181 | than time from startup intervals. Much improved support for IPv6 table | |
182 | dumps. show commands for views improved. | |
183 | ||
5ae016ee | 184 | * Changes in Quagga 0.96.3 |
185 | ||
186 | - revert the 'generic PtP' patch. Means Quagga will no longer work with | |
187 | FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs | |
188 | which the PtP patch introduced. | |
189 | ||
9491975e | 190 | * Changes in Quagga 0.96.2 |
191 | ||
192 | - Fix crash in ospfd | |

201 | the documentation for details. | |
202 | ||
203 | - NSSA ABR support in ospfd. | |
204 | ||
205 | - OSPF-API support merged in. | |

718e3744 | 243 | * Changes in zebra-0.92 |
244 | ||
245 | ** Overall security is improved. Default umask is 0077. | |
246 | ||
247 | * Changes in ripd | |
248 | ||
249 | ** If output interface is in simple password authentication mode, | |
250 | substruct one from rtemax. | |
251 | ||
252 | * Changes in bgpd | |
253 | ||
254 | ** IPv4 multicast and IPv6 unicast configuration is changed to so | |
255 | called new config. All of AFI and SAFI specific configuration is | |
256 | moved to "address-family" node. When you have many IPv6 only | |
257 | configuration, you will see many "no neighbor X:X::X:X activate" line | |
258 | in your configuration to disable IPv4 unicast NLRI exchange. In that | |
259 | case please use "no bgp default ipv4-unicast" command to suppress the | |
260 | output. Until zebra-0.93, old config is still left for compatibility. | |

406 | ||
407 | ** Fix PointoPoint interface network bug. The destination network | |
408 | should be installed into routing table instead of local network. | |
409 | ||
410 | ** Metric value is reflected to kernel routing table. | |
411 | ||
412 | ** "show ip route" display uptime of RIP,OSPF,BGP routes. | |
413 | ||
414 | ** New RIB implementation is added. | |
415 | ||
416 | Now we have enhanced RIB (routing information base) implementation in | |
417 | zebra. New RIB has many new features and fixed some bugs which exist | |
418 | in old RIB code. | |
419 | ||
420 | *** Static route with distance value | |
421 | ||
422 | Static route can be specified with administrative distance. The | |
423 | distance value 255 means it is not installed into the kernel. | |
424 | Default value of distance for static route is 1. | |
425 | ||
426 | ip route A.B.C.D/M A.B.C.D <1-255> | |
427 | ip route A.B.C.D/M IFNAME <1-255> | |
428 | ||
429 | If the least distance value's route's nexthop are unreachable, | |
430 | select the least distance value route which has reachable nexthop is | |
431 | selected. | |
432 | ||
433 | ip route 0.0.0.0/0 10.0.0.1 | |
434 | ip route 0.0.0.0/0 11.0.0.1 2 | |
435 | ||
436 | In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is | |
437 | reachable. The route with nexthop 11.0.0.1 will be installed into | |
438 | forwarding table. | |
439 | ||
440 | zebra> show ip route | |
441 | S>* 0.0.0.0/0 [2/0] via 11.0.0.1 | |
442 | S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive | |
443 | ||
444 | If the nexthop is unreachable "inactive" is displayed. You can | |
445 | specify any string to IFNAME. There is no need of the interface is | |
446 | there when you configure the route. | |
447 | ||
448 | ip route 1.1.1.1/32 ppp0 | |
449 | ||
450 | When ppp0 comes up, the route is installed properly. | |
451 | ||
452 | *** Multiple nexthop routes for one prefix | |
453 | ||
454 | Multiple nexthop routes can be specified for one prefix. Even the | |
455 | kernel support only one nexthop for one prefix user can configure | |
456 | multiple nexthop. | |

458 | When you configure routes like below, prefix 10.0.0.1 has three | |
459 | nexthop. | |
460 | ||
461 | ip route 10.0.0.1/32 10.0.0.2 | |
462 | ip route 10.0.0.1/32 10.0.0.3 | |
463 | ip route 10.0.0.1/32 eth0 | |
464 | ||
465 | If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0 | |
466 | is reachable, then the last route is installed into the kernel. | |
467 | ||
468 | zebra> show ip route | |
469 | S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive | |
470 | via 10.0.0.3 inactive | |
471 | * is directly connected, eth0 | |
472 | ||
473 | '*' means this nexthop is installed into the kernel. | |
474 | ||
475 | *** Multipath (more than one nexthop for one prefix) can be installed into the kernel. | |
476 | ||
477 | When the kernel support multipath, zebra can install multipath | |
478 | routes into the kernel. Before doing that please make it sure that | |
479 | setting --enable-multipath=ARG to configure script. ARG must be digit | |
480 | value. When specify 0 to ARG, there is no limitation of the number | |
481 | of the multipath. Currently only GNU/Linux with netlink interface is | |
482 | supported. | |
483 | ||
484 | ip route 10.0.0.1/32 10.0.0.2 | |
485 | ip route 10.0.0.1/32 10.0.0.3 | |
486 | ip route 10.0.0.1/32 eth0 | |
487 | ||
488 | zebra> show ip route | |
489 | S>* 10.0.0.1/32 [1/0] via 10.0.0.2 | |
490 | * via 10.0.0.3 | |
491 | is directly connected, eth0 | |
492 | ||
493 | *** Kernel message delete installed route. | |
494 | ||
495 | After zebra install static or dynamic route into the kernel. | |
496 | ||
497 | R>* 0.0.0.0/0 [120/3] via 10.0.0.1 | |
498 | ||
499 | If you delete this route outside zebra, old zebra does not reinstall | |
500 | route again. Now the route is re-processed and properly reinstall the | |
501 | static or dynamic route into the kernel. | |
502 | ||
503 | ** GNU/Linux netlink socket handling is improved to fix race condition | |
504 | between kernel message and user command responce. | |
505 | ||
506 | * Changes in bgpd | |
507 | ||
508 | ** Add show neighbor's routes command. | |
509 | ||
510 | "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes" | |
511 | "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes" | |
512 | "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes" | |
513 | "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes" | |
514 | ||
515 | ** BGP passive peer support problem is fixed. | |
516 | ||
517 | ** Redistributed IGP nexthop is passed to BGP nexthop. | |
518 | ||
519 | ** On multiaccess media, if the nexthop is reachable nexthop is passed | |
520 | as it is. | |
521 | ||
522 | ** Remove zebra-0.88 compatibility commands. | |
523 | ||
524 | "match ip prefix-list WORD" | |
525 | "match ipv6 prefix-list WORD" | |
526 | ||
527 | Instead of above please use below commands. | |
528 | ||
529 | "match ip address prefix-list WORD" | |
530 | "match ipv6 address prefix-list WORD" | |
531 | ||
532 | ** Fix bug of holdtimer is not reset when bgp cleared. | |
533 | ||
534 | ** "show ip bgp summary" display peer establish/drop count. | |
535 | ||
536 | ** Change "match ip next-hop" argument from IP address to access-list | |
537 | name. | |
538 | ||
539 | ** When "bgp enforce-first-as" is enabled, check EBGP peer's update | |
540 | has it's AS number in the first AS number in AS sequence. | |
541 | ||
542 | ** New route-map command "set community-delete COMMUNITY-LIST" is | |
543 | added. Community matched the CoMMUNITY-LIST is removed from the | |
544 | community. | |
545 | ||
546 | ** BGP-MIB implementation is finished. | |
547 | ||
548 | ** When BGP connection comes from unconfigured IP address, close | |
549 | socket immediately. | |
550 | ||
551 | ** Do not compare router ID when the routes comes from EBGP peer. | |
552 | When originator ID is same, take shorter cluster-list route. If | |
553 | cluster-list is same take smaller IP address neighbor's route. | |
554 | ||
555 | ** Add "bgp bestpath as-path ignore" command. When this option is | |
556 | set, do not concider AS path length when route selection. | |
557 | ||
558 | ** Add "bgp bestpath compare-routerid". When this option is set, | |
559 | compare router ID when the routes comes from EBGP peer. | |
560 | ||
561 | ** Add "bgp deterministic-med" process. | |
562 | ||
563 | ** BGP flap dampening feature is added. | |

576 | ||
577 | ** Memory leak related classfull network generation is fixed. | |
578 | ||
579 | ** When a route is in garbage collection process (invalid with metric | |
580 | 16) and a router receives the same route with valid metric then route | |
581 | was not installed into zebra rib, but only into ripd rib. Moreover , | |
582 | it will never get into zebra rib, because ripd wrongly assumes it's | |
583 | already there. | |
584 | ||
585 | * Change in ospfd | |
586 | ||
587 | ** Fix bug of refreshing default route. | |

599 | with interface priority 0). It's router LSA does not contain the link | |
600 | information about this network. | |
601 | ||
602 | ** When you change a priority of interface from/to 0 | |
603 | ISM_NeighborChange event should be scheduled in order to elect new | |
604 | DR/BDR on the network. | |
605 | ||
606 | ** When we add some LSA into retransmit list we need to check whether | |
607 | the present old LSA in retransmit list is not more recent than the new | |
608 | one. | |
609 | ||
610 | ** In states Loading and Full the slave must resend its last Database | |
611 | Description packet in response to duplicate Database Description | |
612 | packets received from the master. For this reason the slave must wait | |
613 | RouterDeadInterval seconds before freeing the last Database | |
614 | Description packet. Reception of a Database Description packet from | |
615 | the master after this interval will generate a SeqNumberMismatch | |
616 | neighbor event. RFC2328 Section 10.8 | |
617 | ||
618 | ** Virtual link can not configured in stub area. | |
619 | ||

674 | ** When -b option is specified to vtysh, vtysh read | |
675 | /usr/local/etc/Zebra.conf file then pass the confuguration to proper | |
676 | protocol daemon. So make all protocol daemon's configuration file | |

718e3744 | 1129 | * Changes in zebra-0.84 |
1130 | ||
1131 | * Changes in lib | |
1132 | ||
1133 | ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada | |
1134 | <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address, | |
1135 | "X:X::X:X/M" for IPv6 prefix. You can use it like this. | |
1136 | ||
1137 | DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>") | |
1138 | ||
1139 | ** VTY configuration is locked during configuration. This is for | |
1140 | avoiding unconditional crush from two terminals modify the | |
1141 | configuration at the same time. "who" command shows which termnal | |
1142 | lock the configuration. VTY which has '*' character at the head of | |
1143 | line is locking the configuration. | |
1144 | ||
1145 | ** Old logging functions are removed. Functions like | |
1146 | log_open,log_close,openlog are deleted. Instead of that please use | |
1147 | zlog_* functions. zvlog_* used in ospf6d are deleted also. | |
1148 | ||
1149 | ** "terminal monitor" command is added. "no terminal monitor" is for | |
1150 | disabling. This command simply display logging information to the | |
1151 | VTY. | |
1152 | ||
1153 | ** dropline.[ch] files are deleted. | |
1154 | ||
1155 | * Changes in bgpd | |
1156 | ||
1157 | ** BGP neighbor configuration are sorted by it's IP address. | |
1158 | ||
1159 | ** BGP peer configuration and actual peer is separated. This is | |
1160 | preparation for Route Server support. | |
1161 | ||
1162 | ** "no neighbor PEER" command is added. You can delete neighbor | |
1163 | without specifying AS number. | |
1164 | ||
1165 | ** "no neighbor ebgp-multihop" command is added. | |
1166 | ||
1167 | ** "no neighbor port PORT" command is added. | |
1168 | ||
1169 | ** To conform RFC1771, "neighbor PEER send-community" is default | |
1170 | behavior. If you want to disable sending community attribute, | |
1171 | please specify "no neighbor PEER send-community" to the peer. | |
1172 | ||
1173 | ** "neighbor maximum-prefix NUMBER" command is added. | |
1174 | ||
1175 | ** Multi-protocol extention NLRI is proceeded only when the peer is | |
1176 | configured proper Address Family and Subsequent Address Family. If | |
1177 | not, those NLRI are simply ignored. | |
1178 | ||
1179 | ** Aggregate-address support is improved. Currently below commands | |
1180 | works. | |
1181 | ||
1182 | "aggregate-address" | |
1183 | "aggregate-address summary-only" | |
1184 | "no aggregate-address" | |

1191 | ||
1192 | ** redistribute route-map bug is fixed. | |
1193 | ||
1194 | ** MBGP support becomes default. "configure" option --enable-mbgp is | |
1195 | removed. | |
1196 | ||
1197 | ** New command "neighbor PEER timers connect <1-65535>" is added. | |
1198 | ||
1199 | ** New command "neighbor PEER override-capability" is added. | |
1200 | ||
1201 | ** New command "show ip bgp neighbor A.B.C.D advertised-route" is added. | |
1202 | ||
1203 | ** New command "show ip bgp neighbor A.B.C.D routes" is added. To use | |
1204 | this command, you have to configure neighbor with | |
1205 | "neighbor A.B.C.D soft-reconfiguration inbound" beforehand. | |
1206 | ||
6b0655a2 | 1207 | |
718e3744 | 1208 | * Changes in zebra-0.83 |
1209 | ||
1210 | * bgpd | |
1211 | ||
1212 | ** Serious bug fix about fetching global and link-local address at the | |
1213 | same time. Due to this bug, corrupted IPv6 prefix is generated. If | |
1214 | you uses bgpd for BGP-4+ please update to this version. The bug is | |
1215 | introduced in zebra-0.82. | |
1216 | ||
1217 | ** When bgpd send Notify message, don't use thread manager. It is now | |
1218 | send to neighbor immediately. | |
6b0655a2 | 1219 | |
718e3744 | 1220 | * Changes in zebra-0.82 |
1221 | ||
1222 | ** Solaris 2.6 support is added by Michael Handler | |
1223 | <handler@sub-rosa.com>. | |
1224 | ||
1225 | ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>. | |
1226 | Please specify --enable-mbgp to configure script. This option will be | |
1227 | removed in the future and MBGP support will be default. | |
1228 | ||
1229 | * Changes in zebra | |
1230 | ||
1231 | ** When interface goes down, withdraw connected routes from routing | |
1232 | table. When interface goes up, restore the routes to the routing | |
1233 | table. | |
1234 | ||
1235 | ** `show interface' show interface's statistics on Linux and BSD with | |
1236 | routing socket. | |
1237 | ||
1238 | ** Now zebra can get MTU value on BSDI/OS. | |
1239 | ||
1240 | * Changes in bgpd | |
1241 | ||
1242 | ** Add capability option support based upon | |
1243 | draft-ietf-idr-bgp4-cap-neg-04.txt. | |
1244 | ||
1245 | ** Add `show ipv6 bgp prefix-list' command. | |
1246 | ||
1247 | ** Check self AS appeared in received routes. | |
1248 | ||
1249 | ** redistribute route-map support is added. | |
1250 | ||
1251 | ** BGP packet dump feature compatible with MRT. | |
1252 | ||
1253 | * Changes in ripd | |
1254 | ||
1255 | ** Fix bug of `timers basic' command's argument format. | |
1256 | ||
1257 | * Changes in ripngd | |
1258 | ||
1259 | ** Calculate max RTE using interface's MTU value. | |
1260 | ||
1261 | * Changes in ospfd | |
1262 | ||
1263 | ** Some correction to LSU processing. | |
1264 | ||
1265 | ** Add check for lsa->refresh_list. | |
1266 | ||
1267 | * Changes in ospf6d | |
1268 | ||
1269 | ** Many debug feature is added. | |
6b0655a2 | 1270 | |
718e3744 | 1271 | * Changes in zebra-0.81 |
1272 | ||
1273 | ** SNMP support is disabled in default.--enable-snmp option is added | |
1274 | to configure script. | |
1275 | ||
1276 | * Changes in bgpd | |
1277 | ||
1278 | ** Fix FSM bug which introduced in zebra-0.80. | |
6b0655a2 | 1279 | |
718e3744 | 1280 | * Changes in zebra-0.80 |
1281 | ||
1282 | * access-list | |
1283 | ||
1284 | New access-list name space `ipv6 access-list' is added. At the same | |
1285 | time, `access-list' statemant only accepts IPv4 prefix. Please be | |
1286 | careful if you use IPv6 filtering. You will need to change your | |
1287 | configuration. For IPv6 filtering please use `ipv6 access-list'. | |
1288 | ||
1289 | As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6 | |
1290 | filtering. | |
1291 | ||
1292 | ! zebra-0.7x | |
1293 | access-list DML-net permit 203.181.89.0/24 | |
1294 | access-list DML-net permit 3ffe:506::0/32 | |
1295 | access-list DML-net deny any | |
1296 | ! | |
1297 | ||
1298 | Above configuration is not valid for zebra-08x. Please add `ipv6' | |
1299 | before 'access-list' when you configure IPv6 filtering. | |
1300 | ||
1301 | ! zebra-0.8x | |
1302 | access-list DML-net permit 203.181.89.0/24 | |
1303 | access-list DML-net deny any | |
1304 | ! | |
1305 | ipv6 access-list DML-net permit 3ffe:506::0/32 | |
1306 | ipv6 access-list DML-net deny any | |
1307 | ! | |
1308 | ||
1309 | * prefix-list | |
1310 | ||
1311 | And also new prefix-list name space `ipv6 prefix-list' is added. It | |
1312 | is the same as the change of `access-list'. `ip prefix-list' now only | |
1313 | accept IPv4 prefix. It was source of confusion that `ip prefix-list' | |
1314 | can be used both IPv4 and IPv6 filtering. Now name space is separated | |
1315 | to clear the meaning of the filter. | |
1316 | ||
1317 | If you use `ip prefix-list' for IPv6 filtering, please change the | |
1318 | stetement. | |
1319 | ||
1320 | ! zebra-0.7x | |
1321 | ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24 | |
1322 | ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28 | |
1323 | ip prefix-list 6bone-filter seq 12 deny 3ffe::/16 | |
1324 | ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16 | |
1325 | ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35 | |
1326 | ip prefix-list 6bone-filter seq 30 deny any | |
1327 | ! | |
1328 | ||
1329 | Now user can explicitly configure it as IPv6 prefix-list. | |
1330 | ||
1331 | ! zebra-0.8x | |
1332 | ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24 | |
1333 | ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28 | |
1334 | ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16 | |
1335 | ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16 | |
1336 | ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35 | |
1337 | ipv6 prefix-list 6bone-filter seq 30 deny any | |
1338 | ! | |
1339 | ||
1340 | * RIP configuration | |
1341 | ||
1342 | If you want to filter only default route (0.0.0.0/0) and permit other | |
1343 | routes, it was hard to do that. Now `ip prefix-list' can be used for | |
1344 | RIP route filtering. | |
1345 | ||
1346 | New statement: | |
1347 | ||
1348 | `distribute-list prefix PLIST_NAME (in|out) IFNAME' | |
1349 | ||
1350 | is added to ripd. So you can configure on eth0 interface accept all | |
1351 | routes other than default routes. | |
1352 | ||
1353 | ! | |
1354 | router rip | |
1355 | distribute-list prefix filter-default in eth0 | |
1356 | ! | |
1357 | ip prefix-list filter-default deny 0.0.0.0/0 le 0 | |
1358 | ip prefix-list filter-default permit any | |
1359 | ! | |
1360 | ||
1361 | * RIPng configuration | |
1362 | ||
1363 | Same change is done for ripngd. You can use `ipv6 prefix-list' for | |
1364 | filtering. | |
1365 | ||
1366 | ! | |
1367 | router ripng | |
1368 | distribute-list prefix filter-default in eth0 | |
1369 | ! | |
1370 | ipv6 prefix-list filter-default deny ::/0 le 0 | |
1371 | ipv6 prefix-list filter-default permit any | |
1372 | ! | |
1373 | ||
1374 | * BGP configuration | |
1375 | ||
1376 | So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is | |
1377 | done with traditional IPv4 peering statement like blow. | |
1378 | ||
1379 | ! | |
1380 | router bgp 7675 | |
1381 | neighbor 3ffe:506::1 remote-as 2500 | |
1382 | neighbor 3ffe:506::1 prefix-list 6bone-filter out | |
1383 | ! | |
1384 | ||
1385 | For separating configuration IPv4 and IPv6, and for retaining Cisco | |
1386 | configuration compatibility, now IPv6 configuration is done by IPv6 | |
1387 | specific statement. IPv6 BGP configuration is done by statement which | |
1388 | start from `ipv6 bgp'. | |
1389 | ||
1390 | ! | |
1391 | router bgp 7675 | |
1392 | ! | |
1393 | ipv6 bgp neighbor 3ffe:506::1 remote-as 2500 | |
1394 | ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out | |
1395 | ! | |
1396 | ||
1397 | At the same time some IPv6 specific commands are deleted from IPv4 | |
1398 | configuration. | |
1399 | ||
1400 | o redistribute ripng | |
1401 | o redistribute ospf6 | |
1402 | o neighbor PEER version BGP_VERSION | |
1403 | o neighbor PEER interface IFNAME | |
1404 | ||
1405 | Those commands are only accepted as like below. | |
1406 | ||
1407 | o ipv6 bgp redistribute ripng | |
1408 | o ipv6 bgp redistribute ospf6 | |
1409 | o ipv6 bgp neighbor PEER version BGP_VERSION | |
1410 | o ipv6 bgp neighbor PEER interface IFNAME | |
1411 | ||
1412 | And below new commands are added. | |
1413 | ||
1414 | o ipv6 bgp network IPV6_PREFIX | |
1415 | o ipv6 bgp redistribute static | |

1440 | I hope these changes are easy to understand for current Zebra users... | |
1441 | ||
1442 | * To restrict connection to VTY interface. | |
1443 | ||
1444 | It used to be both IPv4 and IPv6 filter can be specified with one | |
1445 | access-list. Then the access-list can be appried to VTY interface | |
1446 | with `access-class' stetement in `line vty' node. Below is example in | |
1447 | zebra-0.7x. | |
1448 | ||
1449 | ! | |
1450 | access-list local-only permit 127.0.0.1/32 | |
1451 | access-list local-only permit ::1/128 | |
1452 | access-list local-only deny any | |
1453 | ! | |
1454 | line vty | |
1455 | access-class local-only | |
1456 | ! | |
1457 | ||
1458 | Now IPv4 and IPv6 filter have each name space. It is not possible to | |
1459 | specify IPv4 and IPv6 filter with one access-list. For setting IPv6 | |
1460 | access-list in `line vty', `ipv6 access-class' statement is | |
1461 | introduced. Let me show the configuration in zebra-0.8x. | |
1462 | ||
1463 | ! | |
1464 | access-list local-only permit 127.0.0.1/32 | |
1465 | access-list local-only deny any | |
1466 | ! | |
1467 | ipv6 access-list local-only permit ::1/128 | |
1468 | ipv6 access-list local-only dny any | |
1469 | ! | |
1470 | line vty | |
1471 | access-class local-only | |
1472 | ipv6 access-class local-only | |
1473 | ! | |
1474 | ||
1475 | * route-map | |
1476 | ||
1477 | New IPv6 related route-map match commands are added. | |
1478 | ||
1479 | o match ipv6 address | |
1480 | o match ipv6 next-hop | |
1481 | ||
1482 | Please change your configuration if you use IP match statement for | |
1483 | IPv6 route. | |
1484 | ||
1485 | zebra-0.7x config | |
1486 | ================= | |
1487 | ! | |
1488 | access-list all permit any | |
1489 | ! | |
1490 | route-map set-nexthop permit 10 | |
1491 | match ip address all | |
1492 | set ipv6 next-hop global 3ffe:506::1 | |
1493 | set ipv6 next-hop local fe80::cbb5:591a | |
1494 | ! | |
1495 | ||
1496 | zebra-0.8x config | |
1497 | ================= | |
1498 | ! | |
1499 | ipv6 access-list all permit any | |
1500 | ! | |
1501 | route-map set-nexthop permit 10 | |
1502 | match ipv6 address all | |
1503 | set ipv6 next-hop global 3ffe:506::1 | |
1504 | set ipv6 next-hop local fe80::cbb5:591a | |
1505 | ! | |
1506 | ||
1507 | * zebra connection | |
1508 | ||
1509 | Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon | |
1510 | when the connection fail. Those daemons try to connect zebra every 10 | |
1511 | seconds first three trial, then the interval changed to 60 seconds. | |
1512 | After all, if ten connections are fail, protocol daemon give up the | |
1513 | connection to the zebra daemon. | |
1514 | ||
1515 | * SNMP support (is not yet finished) | |
1516 | ||
1517 | Zebra uses SMUX protocol (RFC1227) for making communication with SNMP | |
1518 | agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1 | |
1519 | and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be | |
1520 | compiled with ucd-snmp-3.6.2. | |
1521 | ||
1522 | After applying the patch to ucd-snmp-4.0.1, please configure it with | |
1523 | SMUX module. | |
1524 | ||
1525 | % configure --with-mib-modules=smux | |
1526 | ||
1527 | After compile & install ucd-snmp-4.0.1, you will need to configure | |
1528 | smuxpeer. I'm now using below configuration. | |
1529 | ||
1530 | /usr/local/share/snmp/snmpd.conf | |
1531 | ================================ | |
1532 | smuxpeer 1.3.6.1.6.3.1 test | |
1533 | ||
1534 | Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard | |
1535 | coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP. | |
1536 | ||
1537 | * HUP signal treatment | |
1538 | ||
1539 | From zebra-0.80, ripd will reload it's configuration file when ripd | |
1540 | receives HUP signal. Other daemon such as bgpd, ospfd will support | |
1541 | HUP signal treatment soon. | |
