3 * Changes in Quagga 0.99.21
5 - [bgpd] BGP multipath support has been merged
6 - [bgpd] SAFI (Multicast topology) support has been extended to propagate
8 - [bgpd] AS path limit functionality has been removed
9 - [babeld] a new routing daemon implementing the BABEL ad-hoc mesh routing
10 protocol has been merged.
11 - [isisd] a major overhaul has been picked up. Please note that isisd is
12 STILL NOT SUITABLE FOR PRODUCTION USE.
13 - [*] a lot of bugs have been fixed, please refer to the git log
15 * Changes in Quagga 0.99.10
17 - [bgpd] 4-byte AS support added
18 - [bgpd] MRT format changes to version 2. Those relying on
19 bgpd MRT table dumps may need to update their tools.
20 - [bgpd] Added new route-map set statement: "as-path exclude"
21 - Zebra RIB updates queue has evolved into a multi-level
22 structure to address RIB consistency issues.
24 * Changes in Quagga 0.99.2
26 - [bgpd] Work queues added to bgpd to split up update processing,
27 particularly beneficial when a peer session goes down. AS_PATH
28 parsing rewritten to be clearer, more robust and ready for 4-byte.
30 - [ripd] Simple authentication is no longer the default authentication
31 mode for ripd. The default is now no-authentication. Any setups which
32 used simple authentication will probably need to update their
33 configuration manually.
35 - [ospfd] 1s dead-interval with sub-second Hellos feature added.
36 SPF timers now specified in milliseconds, and with adaptive
37 hold-time support. RFC3137 Stub-router support added. Default ABR
40 - Solaris least privileges support added.
42 * Changes in Quagga 0.99.1
44 - Zserv is now buffered via threads and non-blocking in most cases for both
45 clients and zebra, which should improve responsiveness of daemons when
46 they must send many messages to zebra.
48 - 'show thread cpu' now displays both cpu+system and wall-clock time,
49 where getrusage() is available.
51 - Background threads added and workqueue API added, with a
52 'show work-queues' command. Thread scheduling improved slightly.
54 - Zebra now has a work-queue for RIB processing. See 'show work-queues' in
57 - Support for interface renaming on Linux netlink systems.
59 - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip
60 route-source" command.
62 - Automatic logging of backtraces should daemons crash to assist in
63 diagnosis. See the documentation for more information on configuring
64 logging correctly, and set --enable-gcc-rdynamic if compiling with gcc.
66 * Changes in Quagga 0.98.0
68 - Logging facilities upgraded. One can now specify a severity level
69 for each logging destination. And a new "show logging" command gives
70 thorough information on the current logging system configuration.
72 - Watchquagga daemon added. This is not well tested yet. Please try
73 monitor mode first before enabling restart features. It is important
74 to make sure that the various timers are configured with appropriate
77 - BGP route-server support added. See the texinfo documentation.
79 - OSPF API initialisation is disabled by default even if compiled in. You
80 can enable it with -a/--apiserver command line switch.
82 - "write-config integrated" vtysh command replaced with "service
83 integrated-vtysh-config" command.
85 - Router id is now handled by zebra daemon and all daemons receive changes
86 from it. Router id can be overriden in daemons' configurations of course.
87 To fix common router id in zebra daemon you can either install non-127
88 address on loopback or use "router-id x.x.x.x" command.
90 - "secondary" keyword is removed from ip address configuration. All
91 supported OS'es have their own vision what's secondary address and
94 - Zebra no longer enables forwarding by default. If you rely on zebra to
95 enable forwarding make sure to add '<ip|ip6> forwarding' statements
96 to your zebra configuration file.
98 - All libraries are built and used shared, on platforms where libtool
99 supports shared libraries.
101 - Router advertisement syntax is changed. In usual cases (if you didn't do
102 any fancy stuff) it's enough to change lines in configuration from:
103 "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link"
105 "ipv6 nd prefix X:X:X:X::/X"
107 All router advertisement options are documented in texi documentation.
109 - --enable-nssa configure switch is removed. NSSA support is stable enough.
111 - Daemons don't look at current directory for config file any more.
113 * Changes in Quagga 0.96.5
115 - include files are installed in $(prefix)/include/quagga. Programs
116 building against these includes should -I$(prefix)/include and e.g.
117 #include <quagga/routemap.h>
119 - New option --enable-exampledir puts example files in a separate
120 directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules
123 - New configure options --enable-configfile-mask and
124 --enable-logfile-mask to set umask values for config and log
125 values. Masks default to 0600, matching previous behavior.
127 - Import current CVS isisd from SourceForge, then merge it with
128 the Quagga's Framework.
130 * Changes in Quagga 0.96.4
132 - Further fixes to ospfd, some relating to the PtP revert. Interface
133 lookups should be a lot more robust now.
135 - Fix for a remote triggerable crash in vty layer.
137 - Improvements to ripd, and addition of split horizon support.
139 - Improved bgpd table support, now dumps at time of day intervals rather
140 than time from startup intervals. Much improved support for IPv6 table
141 dumps. show commands for views improved.
143 * Changes in Quagga 0.96.3
145 - revert the 'generic PtP' patch. Means Quagga will no longer work with
146 FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs
147 which the PtP patch introduced.
149 * Changes in Quagga 0.96.2
153 * Changes in Quagga 0.96.1
155 - Iron out problem with the privileges definitions
157 * Changes in Quagga 0.96
159 - Privilege support, daemons now run with the minimal privileges needed, see
160 the documentation for details.
162 - NSSA ABR support in ospfd.
164 - OSPF-API support merged in.
166 - 6WIND patch merged in.
168 * Changes in zebra-0.93

202 * Changes in zebra-0.92
204 ** Overall security is improved. Default umask is 0077.
208 ** If output interface is in simple password authentication mode,
209 substruct one from rtemax.
213 ** IPv4 multicast and IPv6 unicast configuration is changed to so
214 called new config. All of AFI and SAFI specific configuration is
215 moved to "address-family" node. When you have many IPv6 only
216 configuration, you will see many "no neighbor X:X::X:X activate" line
217 in your configuration to disable IPv4 unicast NLRI exchange. In that
218 case please use "no bgp default ipv4-unicast" command to suppress the
219 output. Until zebra-0.93, old config is still left for compatibility.

301 ** IPv6 IBGP nexthop change is monitored.
303 ** Unknown transitive attribute is passed with partial flag bit on.
307 ** Fix bug of LSA MaxAge flood.
309 ** Fix bug of NSSA codes.
311 * Changes in zebra-0.90
313 ** From this beta release, --enable-unixdomain and --enable-newrib
314 becomes default. So both options are removed from configure.in. To
315 revert old behavior please specify below option.
317 --enable-tcp-zebra # TCP/IP socket is used for protocol daemon and zebra.
318 --enable-oldrib # Turn on old RIB implementation.
320 Old RIB implementation will be removed in zebra-0.91.
322 ** From this beta release --enable-multipath is supported. This
323 option is only effective on GNU/Linux kernel with
324 CONFIG_IP_ADVANCED_ROUTER and CONFIG_IP_ROUTE_MULTIPATH is set.
326 --enable-multipath=ARG # ARG must be digit. When ARG is 0 unlimit multipath number.
328 ** From this release we do not include guile files.
332 ** newlist.[ch] is merged with linklist.[ch].
334 ** Now Zebra works on MacOS X public beta.
336 ** Access-list can have remark. "access-list WORD remark LINE" define
337 remark for specified access-list.
339 ** Key of key-chain is sorted by it's idetifier value.
341 ** prefix-list rule is slightly changed. The rule of "len <= ge-value
342 <= le-value" is changed to "len < ge-value <= le-value".
344 ** According to above prefix-list rule change, add automatic
345 conversion function of an old rule. ex.) 10.0.0.0/8 ge 8 -> 10.0.0.0/8
348 ** SMUX can handle SNMP trap.
350 ** In our event library, event thread is executed before any other
351 thread like timer, read and write event.
353 ** Robust method for writing configuration file and recover from
354 backing up config file.
356 ** Display "end" at the end of configuration.

360 ** Fix memroy leak about access-list and prefix-list name.
364 ** UNIX domain socket server of zebra protocol is added.
366 ** Fix PointoPoint interface network bug. The destination network
367 should be installed into routing table instead of local network.
369 ** Metric value is reflected to kernel routing table.
371 ** "show ip route" display uptime of RIP,OSPF,BGP routes.
373 ** New RIB implementation is added.
375 Now we have enhanced RIB (routing information base) implementation in
376 zebra. New RIB has many new features and fixed some bugs which exist
379 *** Static route with distance value
381 Static route can be specified with administrative distance. The
382 distance value 255 means it is not installed into the kernel.
383 Default value of distance for static route is 1.
385 ip route A.B.C.D/M A.B.C.D <1-255>
386 ip route A.B.C.D/M IFNAME <1-255>
388 If the least distance value's route's nexthop are unreachable,
389 select the least distance value route which has reachable nexthop is
392 ip route 0.0.0.0/0 10.0.0.1
393 ip route 0.0.0.0/0 11.0.0.1 2
395 In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
396 reachable. The route with nexthop 11.0.0.1 will be installed into
400 S>* 0.0.0.0/0 [2/0] via 11.0.0.1
401 S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
403 If the nexthop is unreachable "inactive" is displayed. You can
404 specify any string to IFNAME. There is no need of the interface is
405 there when you configure the route.
407 ip route 1.1.1.1/32 ppp0
409 When ppp0 comes up, the route is installed properly.
411 *** Multiple nexthop routes for one prefix
413 Multiple nexthop routes can be specified for one prefix. Even the
414 kernel support only one nexthop for one prefix user can configure
417 When you configure routes like below, prefix 10.0.0.1 has three
420 ip route 10.0.0.1/32 10.0.0.2
421 ip route 10.0.0.1/32 10.0.0.3
422 ip route 10.0.0.1/32 eth0
424 If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
425 is reachable, then the last route is installed into the kernel.
428 S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
429 via 10.0.0.3 inactive
430 * is directly connected, eth0
432 '*' means this nexthop is installed into the kernel.
434 *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
436 When the kernel support multipath, zebra can install multipath
437 routes into the kernel. Before doing that please make it sure that
438 setting --enable-multipath=ARG to configure script. ARG must be digit
439 value. When specify 0 to ARG, there is no limitation of the number
440 of the multipath. Currently only GNU/Linux with netlink interface is
443 ip route 10.0.0.1/32 10.0.0.2
444 ip route 10.0.0.1/32 10.0.0.3
445 ip route 10.0.0.1/32 eth0
448 S>* 10.0.0.1/32 [1/0] via 10.0.0.2
450 is directly connected, eth0
452 *** Kernel message delete installed route.
454 After zebra install static or dynamic route into the kernel.
456 R>* 0.0.0.0/0 [120/3] via 10.0.0.1
458 If you delete this route outside zebra, old zebra does not reinstall
459 route again. Now the route is re-processed and properly reinstall the
460 static or dynamic route into the kernel.
462 ** GNU/Linux netlink socket handling is improved to fix race condition
463 between kernel message and user command responce.
467 ** Add show neighbor's routes command.
469 "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes"
470 "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes"
471 "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes"
472 "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes"
474 ** BGP passive peer support problem is fixed.
476 ** Redistributed IGP nexthop is passed to BGP nexthop.
478 ** On multiaccess media, if the nexthop is reachable nexthop is passed
481 ** Remove zebra-0.88 compatibility commands.
483 "match ip prefix-list WORD"
484 "match ipv6 prefix-list WORD"
486 Instead of above please use below commands.
488 "match ip address prefix-list WORD"
489 "match ipv6 address prefix-list WORD"
491 ** Fix bug of holdtimer is not reset when bgp cleared.
493 ** "show ip bgp summary" display peer establish/drop count.
495 ** Change "match ip next-hop" argument from IP address to access-list
498 ** When "bgp enforce-first-as" is enabled, check EBGP peer's update
499 has it's AS number in the first AS number in AS sequence.
501 ** New route-map command "set community-delete COMMUNITY-LIST" is
502 added. Community matched the CoMMUNITY-LIST is removed from the
505 ** BGP-MIB implementation is finished.
507 ** When BGP connection comes from unconfigured IP address, close
510 ** Do not compare router ID when the routes comes from EBGP peer.
511 When originator ID is same, take shorter cluster-list route. If
512 cluster-list is same take smaller IP address neighbor's route.
514 ** Add "bgp bestpath as-path ignore" command. When this option is
515 set, do not concider AS path length when route selection.
517 ** Add "bgp bestpath compare-routerid". When this option is set,
518 compare router ID when the routes comes from EBGP peer.
520 ** Add "bgp deterministic-med" process.
522 ** BGP flap dampening feature is added.
524 ** When IBGP nexthop is changed, it is reflected to RIB.
526 ** Change "neighbor route-refresh" command to "neighbor capability
531 ** Change "match ip next-hop" argument from IP address to access-list
534 ** "no ip rip (send|receive)" command accept version number argument.
536 ** Memory leak related classfull network generation is fixed.
538 ** When a route is in garbage collection process (invalid with metric
539 16) and a router receives the same route with valid metric then route
540 was not installed into zebra rib, but only into ripd rib. Moreover ,
541 it will never get into zebra rib, because ripd wrongly assumes it's
546 ** Fix bug of refreshing default route.
548 ** --enable-nssa turn on undergoing NSSA feature.
550 ** Fix bug of Hello packet's option is not properly set when interface
553 ** Reduce unconditional logging.
555 ** Add nexthop to OSPF path only when it is not there.
557 ** When there is no DR on network (suppose you have only one router
558 with interface priority 0). It's router LSA does not contain the link
559 information about this network.
561 ** When you change a priority of interface from/to 0
562 ISM_NeighborChange event should be scheduled in order to elect new
563 DR/BDR on the network.
565 ** When we add some LSA into retransmit list we need to check whether
566 the present old LSA in retransmit list is not more recent than the new
569 ** In states Loading and Full the slave must resend its last Database
570 Description packet in response to duplicate Database Description
571 packets received from the master. For this reason the slave must wait
572 RouterDeadInterval seconds before freeing the last Database
573 Description packet. Reception of a Database Description packet from
574 the master after this interval will generate a SeqNumberMismatch
575 neighbor event. RFC2328 Section 10.8
577 ** Virtual link can not configured in stub area.
579 ** Clear a ls_upd_queue queue of the interface when interface goes
582 ** "no router ospf" unregister redistribution requests from zebra.
584 ** New command for virtual-link configuration is added.
586 "area A.B.C.D virtual-link A.B.C.D"
587 "area A.B.C.D virtual-link A.B.C.D hello-interval <1-65535> retransmit-interval <3-65535> transmit-delay <1-65535> dead-interval <1-65535>"
588 "area A.B.C.D virtual-link A.B.C.D hello-interval <1-65535> retransmit-interval <3-65535> transmit-delay <1-65535> dead-interval <1-65535> authentication-key AUTH_KEY"

590 "area A.B.C.D virtual-link A.B.C.D hello-interval <1-65535> retransmit-interval <3-65535> transmit-delay <1-65535> dead-interval <1-65535> message-digest-key <1-255> md5 KEY"
591 "area A.B.C.D virtual-link A.B.C.D message-digest-key <1-255> md5 KEY"
593 ** Clear cryptographic sequence number when neighbor status is changed
596 ** Make Summary LSA's origination and refreshment as same as other
599 ** New OSPF pakcet read method. Now maximum packet length may be 65535
600 bytes (maximum IP packet length).
602 ** Checking the age of the found LSA and if the LSA is MAXAGE we
603 should call refresh instead of originate.
605 ** Install multipath information to zebra.
607 ** Fix socket descriptor leak when system call failed.
611 ** Whole functionality has been rewritten as new code. new command
612 "show ipv6 ospf6 spf node", "show ipv6 ospf6 spf tree", "show ipv6

615 ** Change to do not send garbage route whose nexthop is not linklocal
618 ** "redistribute ospf6" was generated in "router ospf6" in config
621 ** LSDB sync bug is fixed.
623 ** Fix bug of using unavailable route.
627 ** route-map and access-list configuration is merged into one
630 ** /usr/local/etc/Zebra.conf is integrated configuration file. "write
631 memory" in vtysh will write whole configuration to this file.
633 ** When -b option is specified to vtysh, vtysh read
634 /usr/local/etc/Zebra.conf file then pass the confuguration to proper
635 protocol daemon. So make all protocol daemon's configuration file
636 empty then invoke all daemon. After that vtysh -b will setup saved

1088 * Changes in zebra-0.84
1092 ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada
1093 <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address,
1094 "X:X::X:X/M" for IPv6 prefix. You can use it like this.
1096 DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>")
1098 ** VTY configuration is locked during configuration. This is for
1099 avoiding unconditional crush from two terminals modify the
1100 configuration at the same time. "who" command shows which termnal
1101 lock the configuration. VTY which has '*' character at the head of
1102 line is locking the configuration.
1104 ** Old logging functions are removed. Functions like
1105 log_open,log_close,openlog are deleted. Instead of that please use
1106 zlog_* functions. zvlog_* used in ospf6d are deleted also.
1108 ** "terminal monitor" command is added. "no terminal monitor" is for
1109 disabling. This command simply display logging information to the
1112 ** dropline.[ch] files are deleted.
1116 ** BGP neighbor configuration are sorted by it's IP address.
1118 ** BGP peer configuration and actual peer is separated. This is
1119 preparation for Route Server support.
1121 ** "no neighbor PEER" command is added. You can delete neighbor
1122 without specifying AS number.
1124 ** "no neighbor ebgp-multihop" command is added.
1126 ** "no neighbor port PORT" command is added.
1128 ** To conform RFC1771, "neighbor PEER send-community" is default
1129 behavior. If you want to disable sending community attribute,
1130 please specify "no neighbor PEER send-community" to the peer.
1132 ** "neighbor maximum-prefix NUMBER" command is added.
1134 ** Multi-protocol extention NLRI is proceeded only when the peer is
1135 configured proper Address Family and Subsequent Address Family. If
1136 not, those NLRI are simply ignored.
1138 ** Aggregate-address support is improved. Currently below commands
1142 "aggregate-address summary-only"
1143 "no aggregate-address"
1144 "no aggregate-address summary-only"
1146 "ipv6 bgp aggregate-address"
1147 "ipv6 bgp aggregate-address summary-only"
1148 "no ipv6 bgp aggregate-address"

1151 ** redistribute route-map bug is fixed.
1153 ** MBGP support becomes default. "configure" option --enable-mbgp is
1156 ** New command "neighbor PEER timers connect <1-65535>" is added.
1158 ** New command "neighbor PEER override-capability" is added.
1160 ** New command "show ip bgp neighbor A.B.C.D advertised-route" is added.
1162 ** New command "show ip bgp neighbor A.B.C.D routes" is added. To use
1163 this command, you have to configure neighbor with
1164 "neighbor A.B.C.D soft-reconfiguration inbound" beforehand.
1167 * Changes in zebra-0.83
1171 ** Serious bug fix about fetching global and link-local address at the
1172 same time. Due to this bug, corrupted IPv6 prefix is generated. If
1173 you uses bgpd for BGP-4+ please update to this version. The bug is
1174 introduced in zebra-0.82.
1176 ** When bgpd send Notify message, don't use thread manager. It is now
1177 send to neighbor immediately.
1179 * Changes in zebra-0.82
1181 ** Solaris 2.6 support is added by Michael Handler
1182 <handler@sub-rosa.com>.
1184 ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>.
1185 Please specify --enable-mbgp to configure script. This option will be
1186 removed in the future and MBGP support will be default.
1190 ** When interface goes down, withdraw connected routes from routing
1191 table. When interface goes up, restore the routes to the routing
1194 ** `show interface' show interface's statistics on Linux and BSD with

1204 ** Add `show ipv6 bgp prefix-list' command.
1206 ** Check self AS appeared in received routes.
1208 ** redistribute route-map support is added.
1210 ** BGP packet dump feature compatible with MRT.
1214 ** Fix bug of `timers basic' command's argument format.
1218 ** Calculate max RTE using interface's MTU value.
1222 ** Some correction to LSU processing.
1224 ** Add check for lsa->refresh_list.
1228 ** Many debug feature is added.
1230 * Changes in zebra-0.81
1232 ** SNMP support is disabled in default.--enable-snmp option is added
1233 to configure script.
1237 ** Fix FSM bug which introduced in zebra-0.80.
1239 * Changes in zebra-0.80
1243 New access-list name space `ipv6 access-list' is added. At the same
1244 time, `access-list' statemant only accepts IPv4 prefix. Please be
1245 careful if you use IPv6 filtering. You will need to change your
1246 configuration. For IPv6 filtering please use `ipv6 access-list'.
1248 As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
1252 access-list DML-net permit 203.181.89.0/24
1253 access-list DML-net permit 3ffe:506::0/32
1254 access-list DML-net deny any
1257 Above configuration is not valid for zebra-08x. Please add `ipv6'
1258 before 'access-list' when you configure IPv6 filtering.
1261 access-list DML-net permit 203.181.89.0/24
1262 access-list DML-net deny any
1264 ipv6 access-list DML-net permit 3ffe:506::0/32
1265 ipv6 access-list DML-net deny any
1270 And also new prefix-list name space `ipv6 prefix-list' is added. It
1271 is the same as the change of `access-list'. `ip prefix-list' now only
1272 accept IPv4 prefix. It was source of confusion that `ip prefix-list'
1273 can be used both IPv4 and IPv6 filtering. Now name space is separated
1274 to clear the meaning of the filter.
1276 If you use `ip prefix-list' for IPv6 filtering, please change the
1280 ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1281 ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1282 ip prefix-list 6bone-filter seq 12 deny 3ffe::/16
1283 ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1284 ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1285 ip prefix-list 6bone-filter seq 30 deny any
1288 Now user can explicitly configure it as IPv6 prefix-list.
1291 ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1292 ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1293 ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16
1294 ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1295 ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1296 ipv6 prefix-list 6bone-filter seq 30 deny any
1301 If you want to filter only default route (0.0.0.0/0) and permit other
1302 routes, it was hard to do that. Now `ip prefix-list' can be used for
1303 RIP route filtering.
1307 `distribute-list prefix PLIST_NAME (in|out) IFNAME'
1309 is added to ripd. So you can configure on eth0 interface accept all
1310 routes other than default routes.
1314 distribute-list prefix filter-default in eth0
1316 ip prefix-list filter-default deny 0.0.0.0/0 le 0
1317 ip prefix-list filter-default permit any
1320 * RIPng configuration
1322 Same change is done for ripngd. You can use `ipv6 prefix-list' for
1327 distribute-list prefix filter-default in eth0
1329 ipv6 prefix-list filter-default deny ::/0 le 0
1330 ipv6 prefix-list filter-default permit any
1335 So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
1336 done with traditional IPv4 peering statement like blow.
1340 neighbor 3ffe:506::1 remote-as 2500
1341 neighbor 3ffe:506::1 prefix-list 6bone-filter out
1344 For separating configuration IPv4 and IPv6, and for retaining Cisco
1345 configuration compatibility, now IPv6 configuration is done by IPv6
1346 specific statement. IPv6 BGP configuration is done by statement which
1347 start from `ipv6 bgp'.
1352 ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
1353 ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
1356 At the same time some IPv6 specific commands are deleted from IPv4
1359 o redistribute ripng
1360 o redistribute ospf6
1361 o neighbor PEER version BGP_VERSION
1362 o neighbor PEER interface IFNAME
1364 Those commands are only accepted as like below.
1366 o ipv6 bgp redistribute ripng
1367 o ipv6 bgp redistribute ospf6
1368 o ipv6 bgp neighbor PEER version BGP_VERSION
1369 o ipv6 bgp neighbor PEER interface IFNAME
1371 And below new commands are added.
1373 o ipv6 bgp network IPV6_PREFIX
1374 o ipv6 bgp redistribute static
1375 o ipv6 bgp redistribute connected
1376 o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
1377 o ipv6 bgp neighbor PEER ebgp-multihop [TTL]
1378 o ipv6 bgp neighbor PEER description DESCRIPTION
1379 o ipv6 bgp neighbor PEER shutdown
1380 o ipv6 bgp neighbor PEER route-reflector-client
1381 o ipv6 bgp neighbor PEER update-source IFNAME
1382 o ipv6 bgp neighbor PEER next-hop-self
1383 o ipv6 bgp neighbor PEER timers holdtime <0-65535>
1384 o ipv6 bgp neighbor PEER timers keepalive <0-65535>
1385 o ipv6 bgp neighbor PEER send-community
1386 o ipv6 bgp neighbor PEER weight <0-65535>
1387 o ipv6 bgp neighbor PEER default-originate
1388 o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out)
1389 o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
1390 o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
1391 o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
1393 And some utility commands are introduced.
1395 o clear ipv6 bgp [PEER]
1396 o show ipv6 bgp neighbors [PEER]
1397 o show ipv6 bgp summary
1399 I hope these changes are easy to understand for current Zebra users...
1401 * To restrict connection to VTY interface.
1403 It used to be both IPv4 and IPv6 filter can be specified with one
1404 access-list. Then the access-list can be appried to VTY interface
1405 with `access-class' stetement in `line vty' node. Below is example in
1409 access-list local-only permit 127.0.0.1/32
1410 access-list local-only permit ::1/128
1411 access-list local-only deny any
1414 access-class local-only
1417 Now IPv4 and IPv6 filter have each name space. It is not possible to
1418 specify IPv4 and IPv6 filter with one access-list. For setting IPv6
1419 access-list in `line vty', `ipv6 access-class' statement is
1420 introduced. Let me show the configuration in zebra-0.8x.
1423 access-list local-only permit 127.0.0.1/32
1424 access-list local-only deny any
1426 ipv6 access-list local-only permit ::1/128
1427 ipv6 access-list local-only dny any
1430 access-class local-only
1431 ipv6 access-class local-only
1436 New IPv6 related route-map match commands are added.
1438 o match ipv6 address
1439 o match ipv6 next-hop
1441 Please change your configuration if you use IP match statement for
1447 access-list all permit any
1449 route-map set-nexthop permit 10
1450 match ip address all
1451 set ipv6 next-hop global 3ffe:506::1
1452 set ipv6 next-hop local fe80::cbb5:591a
1458 ipv6 access-list all permit any
1460 route-map set-nexthop permit 10
1461 match ipv6 address all
1462 set ipv6 next-hop global 3ffe:506::1
1463 set ipv6 next-hop local fe80::cbb5:591a
1468 Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
1469 when the connection fail. Those daemons try to connect zebra every 10
1470 seconds first three trial, then the interval changed to 60 seconds.
1471 After all, if ten connections are fail, protocol daemon give up the
1472 connection to the zebra daemon.
1474 * SNMP support (is not yet finished)
1476 Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
1477 agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
1478 and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
1479 compiled with ucd-snmp-3.6.2.
1481 After applying the patch to ucd-snmp-4.0.1, please configure it with
1484 % configure --with-mib-modules=smux
1486 After compile & install ucd-snmp-4.0.1, you will need to configure
1487 smuxpeer. I'm now using below configuration.
1489 /usr/local/share/snmp/snmpd.conf
1490 ================================
1491 smuxpeer 1.3.6.1.6.3.1 test
1493 Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard
1494 coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP.
1496 * HUP signal treatment
1498 From zebra-0.80, ripd will reload it's configuration file when ripd
1499 receives HUP signal. Other daemon such as bgpd, ospfd will support
1500 HUP signal treatment soon.
1502 * Changes in zebra-0.79
1506 ** Broadcast address setting on Linux box bug is fixed.
1508 ** Protocol daemon can install connected IPv6 route into the kernel.
1510 ** Now zebra can handle blackhole route.
1514 ** Add route-map feature for RIP protocol.
1516 ** In case of RIP version 2 routing table entry has IPv4 address and
1517 netmask pair which host part bit is on, ignore the entry.
1521 ** Change CMSG_DATA cast from (u_char *) to (int *). (u_char *) does
1522 not work for NetBSD-currnet on SparcStation 10.
1526 ** MaxAge LSA treatment is added.
1528 ** ABR/ASBR functionality is added.
1530 ** Virtual Link funtionality is added.
1532 ** ABR behaviors IBM/Cisco/Shortcut is added.
1536 ** Enclosed KAME specific part with #ifdef #endif
1538 * Changes in zebra-0.78
1542 ** SNMP support is started.
1544 ** Now Zebra can work on BSD/OS 4.X.
1546 ** Now Zebra can compiled on vanilla OpenBSD 2.5 but not yet working correcltly.
1550 ** Interface index detection using ioctl() bug is fixed.
1552 ** Interface information protocol is changed. Now interface
1553 addition/deletion and interface's address addition/deletion is
