1 * Changes in Quagga 0.99.2
3 - Work queues added to bgpd to split up update processing, particularly
4 beneficial when a peer session goes down.
6 - Simple authentication is no longer the default authentication mode for
7 ripd. The default is now no-authentication. Any setups which used
8 simple authentication will probably need to update their configuration
11 * Changes in Quagga 0.99.1
13 - Zserv is now buffered via threads and non-blocking in most cases for both
14 clients and zebra, which should improve responsiveness of daemons when
15 they must send many messages to zebra.
17 - 'show thread cpu' now displays both cpu+system and wall-clock time,
18 where getrusage() is available.
20 - Background threads added and workqueue API added, with a
21 'show work-queues' command. Thread scheduling improved slightly.
23 - Zebra now has a work-queue for RIB processing. See 'show work-queues' in
26 - Support for interface renaming on Linux netlink systems.
28 - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip
29 route-source" command.
31 - Automatic logging of backtraces should daemons crash to assist in
32 diagnosis. See the documentation for more information on configuring
33 logging correctly, and set --enable-gcc-rdynamic if compiling with gcc.
35 * Changes in Quagga 0.98.0
37 - Logging facilities upgraded. One can now specify a severity level
38 for each logging destination. And a new "show logging" command gives
39 thorough information on the current logging system configuration.
41 - Watchquagga daemon added. This is not well tested yet. Please try
42 monitor mode first before enabling restart features. It is important
43 to make sure that the various timers are configured with appropriate
46 - BGP route-server support added. See the texinfo documentation.
48 - OSPF API initialisation is disabled by default even if compiled in. You
49 can enable it with -a/--apiserver command line switch.
51 - "write-config integrated" vtysh command replaced with "service
52 integrated-vtysh-config" command.
54 - Router id is now handled by zebra daemon and all daemons receive changes
55 from it. Router id can be overriden in daemons' configurations of course.
56 To fix common router id in zebra daemon you can either install non-127
57 address on loopback or use "router-id x.x.x.x" command.
59 - "secondary" keyword is removed from ip address configuration. All
60 supported OS'es have their own vision what's secondary address and
63 - Zebra no longer enables forwarding by default. If you rely on zebra to
64 enable forwarding make sure to add '<ip|ip6> forwarding' statements
65 to your zebra configuration file.
67 - All libraries are built and used shared, on platforms where libtool
68 supports shared libraries.
70 - Router advertisement syntax is changed. In usual cases (if you didn't do
71 any fancy stuff) it's enough to change lines in configuration from:
72 "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link"
74 "ipv6 nd prefix X:X:X:X::/X"
76 All router advertisement options are documented in texi documentation.
78 - --enable-nssa configure switch is removed. NSSA support is stable enough.
80 - Daemons don't look at current directory for config file any more.
82 * Changes in Quagga 0.96.5
84 - include files are installed in $(prefix)/include/quagga. Programs
85 building against these includes should -I$(prefix)/include and e.g.
86 #include <quagga/routemap.h>
88 - New option --enable-exampledir puts example files in a separate
89 directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules
92 - New configure options --enable-configfile-mask and
93 --enable-logfile-mask to set umask values for config and log
94 values. Masks default to 0600, matching previous behavior.
96 - Import current CVS isisd from SourceForge, then merge it with
97 the Quagga's Framework.
99 * Changes in Quagga 0.96.4
101 - Further fixes to ospfd, some relating to the PtP revert. Interface
102 lookups should be a lot more robust now.
104 - Fix for a remote triggerable crash in vty layer.
106 - Improvements to ripd, and addition of split horizon support.
108 - Improved bgpd table support, now dumps at time of day intervals rather
109 than time from startup intervals. Much improved support for IPv6 table
110 dumps. show commands for views improved.
112 * Changes in Quagga 0.96.3
114 - revert the 'generic PtP' patch. Means Quagga will no longer work with
115 FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs
116 which the PtP patch introduced.
118 * Changes in Quagga 0.96.2
122 * Changes in Quagga 0.96.1
124 - Iron out problem with the privileges definitions
126 * Changes in Quagga 0.96
128 - Privilege support, daemons now run with the minimal privileges needed, see
129 the documentation for details.
131 - NSSA ABR support in ospfd.
133 - OSPF-API support merged in.
135 - 6WIND patch merged in.
137 * Changes in zebra-0.93
141 ** Configuration is changed to new format.
145 ** Crush bugs which reported on Zebra ML is fixed.

171 * Changes in zebra-0.92
173 ** Overall security is improved. Default umask is 0077.
177 ** If output interface is in simple password authentication mode,
178 substruct one from rtemax.
182 ** IPv4 multicast and IPv6 unicast configuration is changed to so
183 called new config. All of AFI and SAFI specific configuration is
184 moved to "address-family" node. When you have many IPv6 only
185 configuration, you will see many "no neighbor X:X::X:X activate" line
186 in your configuration to disable IPv4 unicast NLRI exchange. In that
187 case please use "no bgp default ipv4-unicast" command to suppress the
188 output. Until zebra-0.93, old config is still left for compatibility.

267 "show ipv6 bgp X:X::X:X/M longer-prefixes"
268 "show ipv6 mbgp X:X::X:X/M longer-prefixes"
270 ** IPv6 IBGP nexthop change is monitored.
272 ** Unknown transitive attribute is passed with partial flag bit on.
276 ** Fix bug of LSA MaxAge flood.
278 ** Fix bug of NSSA codes.
280 * Changes in zebra-0.90
282 ** From this beta release, --enable-unixdomain and --enable-newrib
283 becomes default. So both options are removed from configure.in. To
284 revert old behavior please specify below option.
286 --enable-tcp-zebra # TCP/IP socket is used for protocol daemon and zebra.
287 --enable-oldrib # Turn on old RIB implementation.
289 Old RIB implementation will be removed in zebra-0.91.
291 ** From this beta release --enable-multipath is supported. This
292 option is only effective on GNU/Linux kernel with
293 CONFIG_IP_ADVANCED_ROUTER and CONFIG_IP_ROUTE_MULTIPATH is set.
295 --enable-multipath=ARG # ARG must be digit. When ARG is 0 unlimit multipath number.
297 ** From this release we do not include guile files.
301 ** newlist.[ch] is merged with linklist.[ch].
303 ** Now Zebra works on MacOS X public beta.
305 ** Access-list can have remark. "access-list WORD remark LINE" define
306 remark for specified access-list.
308 ** Key of key-chain is sorted by it's idetifier value.
310 ** prefix-list rule is slightly changed. The rule of "len <= ge-value
311 <= le-value" is changed to "len < ge-value <= le-value".
313 ** According to above prefix-list rule change, add automatic
314 conversion function of an old rule. ex.) 10.0.0.0/8 ge 8 -> 10.0.0.0/8
317 ** SMUX can handle SNMP trap.
319 ** In our event library, event thread is executed before any other
320 thread like timer, read and write event.
322 ** Robust method for writing configuration file and recover from
323 backing up config file.
325 ** Display "end" at the end of configuration.
327 ** Fix memory leak in vtysh_read().
329 ** Fix memroy leak about access-list and prefix-list name.
333 ** UNIX domain socket server of zebra protocol is added.
335 ** Fix PointoPoint interface network bug. The destination network
336 should be installed into routing table instead of local network.
338 ** Metric value is reflected to kernel routing table.
340 ** "show ip route" display uptime of RIP,OSPF,BGP routes.
342 ** New RIB implementation is added.
344 Now we have enhanced RIB (routing information base) implementation in
345 zebra. New RIB has many new features and fixed some bugs which exist
348 *** Static route with distance value
350 Static route can be specified with administrative distance. The
351 distance value 255 means it is not installed into the kernel.
352 Default value of distance for static route is 1.
354 ip route A.B.C.D/M A.B.C.D <1-255>
355 ip route A.B.C.D/M IFNAME <1-255>
357 If the least distance value's route's nexthop are unreachable,
358 select the least distance value route which has reachable nexthop is
361 ip route 0.0.0.0/0 10.0.0.1
362 ip route 0.0.0.0/0 11.0.0.1 2
364 In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
365 reachable. The route with nexthop 11.0.0.1 will be installed into
369 S>* 0.0.0.0/0 [2/0] via 11.0.0.1
370 S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
372 If the nexthop is unreachable "inactive" is displayed. You can
373 specify any string to IFNAME. There is no need of the interface is
374 there when you configure the route.
376 ip route 1.1.1.1/32 ppp0
378 When ppp0 comes up, the route is installed properly.
380 *** Multiple nexthop routes for one prefix
382 Multiple nexthop routes can be specified for one prefix. Even the
383 kernel support only one nexthop for one prefix user can configure
386 When you configure routes like below, prefix 10.0.0.1 has three
389 ip route 10.0.0.1/32 10.0.0.2
390 ip route 10.0.0.1/32 10.0.0.3
391 ip route 10.0.0.1/32 eth0
393 If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
394 is reachable, then the last route is installed into the kernel.
397 S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
398 via 10.0.0.3 inactive
399 * is directly connected, eth0
401 '*' means this nexthop is installed into the kernel.
403 *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
405 When the kernel support multipath, zebra can install multipath
406 routes into the kernel. Before doing that please make it sure that
407 setting --enable-multipath=ARG to configure script. ARG must be digit
408 value. When specify 0 to ARG, there is no limitation of the number
409 of the multipath. Currently only GNU/Linux with netlink interface is
412 ip route 10.0.0.1/32 10.0.0.2
413 ip route 10.0.0.1/32 10.0.0.3
414 ip route 10.0.0.1/32 eth0
417 S>* 10.0.0.1/32 [1/0] via 10.0.0.2
419 is directly connected, eth0
421 *** Kernel message delete installed route.
423 After zebra install static or dynamic route into the kernel.
425 R>* 0.0.0.0/0 [120/3] via 10.0.0.1
427 If you delete this route outside zebra, old zebra does not reinstall
428 route again. Now the route is re-processed and properly reinstall the
429 static or dynamic route into the kernel.
431 ** GNU/Linux netlink socket handling is improved to fix race condition
432 between kernel message and user command responce.
436 ** Add show neighbor's routes command.
438 "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes"
439 "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes"
440 "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes"
441 "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes"
443 ** BGP passive peer support problem is fixed.
445 ** Redistributed IGP nexthop is passed to BGP nexthop.
447 ** On multiaccess media, if the nexthop is reachable nexthop is passed
450 ** Remove zebra-0.88 compatibility commands.
452 "match ip prefix-list WORD"
453 "match ipv6 prefix-list WORD"
455 Instead of above please use below commands.
457 "match ip address prefix-list WORD"
458 "match ipv6 address prefix-list WORD"
460 ** Fix bug of holdtimer is not reset when bgp cleared.
462 ** "show ip bgp summary" display peer establish/drop count.
464 ** Change "match ip next-hop" argument from IP address to access-list
467 ** When "bgp enforce-first-as" is enabled, check EBGP peer's update
468 has it's AS number in the first AS number in AS sequence.
470 ** New route-map command "set community-delete COMMUNITY-LIST" is
471 added. Community matched the CoMMUNITY-LIST is removed from the
474 ** BGP-MIB implementation is finished.
476 ** When BGP connection comes from unconfigured IP address, close
479 ** Do not compare router ID when the routes comes from EBGP peer.
480 When originator ID is same, take shorter cluster-list route. If
481 cluster-list is same take smaller IP address neighbor's route.
483 ** Add "bgp bestpath as-path ignore" command. When this option is
484 set, do not concider AS path length when route selection.
486 ** Add "bgp bestpath compare-routerid". When this option is set,
487 compare router ID when the routes comes from EBGP peer.
489 ** Add "bgp deterministic-med" process.
491 ** BGP flap dampening feature is added.
493 ** When IBGP nexthop is changed, it is reflected to RIB.
495 ** Change "neighbor route-refresh" command to "neighbor capability
500 ** Change "match ip next-hop" argument from IP address to access-list
503 ** "no ip rip (send|receive)" command accept version number argument.
505 ** Memory leak related classfull network generation is fixed.
507 ** When a route is in garbage collection process (invalid with metric
508 16) and a router receives the same route with valid metric then route
509 was not installed into zebra rib, but only into ripd rib. Moreover ,
510 it will never get into zebra rib, because ripd wrongly assumes it's
515 ** Fix bug of refreshing default route.
517 ** --enable-nssa turn on undergoing NSSA feature.
519 ** Fix bug of Hello packet's option is not properly set when interface
522 ** Reduce unconditional logging.
524 ** Add nexthop to OSPF path only when it is not there.
526 ** When there is no DR on network (suppose you have only one router
527 with interface priority 0). It's router LSA does not contain the link
528 information about this network.
530 ** When you change a priority of interface from/to 0
531 ISM_NeighborChange event should be scheduled in order to elect new
532 DR/BDR on the network.
534 ** When we add some LSA into retransmit list we need to check whether
535 the present old LSA in retransmit list is not more recent than the new
538 ** In states Loading and Full the slave must resend its last Database
539 Description packet in response to duplicate Database Description
540 packets received from the master. For this reason the slave must wait
541 RouterDeadInterval seconds before freeing the last Database
542 Description packet. Reception of a Database Description packet from
543 the master after this interval will generate a SeqNumberMismatch
544 neighbor event. RFC2328 Section 10.8
546 ** Virtual link can not configured in stub area.
548 ** Clear a ls_upd_queue queue of the interface when interface goes
551 ** "no router ospf" unregister redistribution requests from zebra.
553 ** New command for virtual-link configuration is added.
555 "area A.B.C.D virtual-link A.B.C.D"
556 "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>"

572 should call refresh instead of originate.
574 ** Install multipath information to zebra.
576 ** Fix socket descriptor leak when system call failed.
580 ** Whole functionality has been rewritten as new code. new command

599 ** /usr/local/etc/Zebra.conf is integrated configuration file. "write
600 memory" in vtysh will write whole configuration to this file.
602 ** When -b option is specified to vtysh, vtysh read
603 /usr/local/etc/Zebra.conf file then pass the confuguration to proper
604 protocol daemon. So make all protocol daemon's configuration file
605 empty then invoke all daemon. After that vtysh -b will setup saved

1057 * Changes in zebra-0.84
1061 ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada
1062 <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address,
1063 "X:X::X:X/M" for IPv6 prefix. You can use it like this.
1065 DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>")
1067 ** VTY configuration is locked during configuration. This is for
1068 avoiding unconditional crush from two terminals modify the
1069 configuration at the same time. "who" command shows which termnal
1070 lock the configuration. VTY which has '*' character at the head of
1071 line is locking the configuration.
1073 ** Old logging functions are removed. Functions like
1074 log_open,log_close,openlog are deleted. Instead of that please use
1075 zlog_* functions. zvlog_* used in ospf6d are deleted also.
1077 ** "terminal monitor" command is added. "no terminal monitor" is for
1078 disabling. This command simply display logging information to the
1081 ** dropline.[ch] files are deleted.
1085 ** BGP neighbor configuration are sorted by it's IP address.
1087 ** BGP peer configuration and actual peer is separated. This is
1088 preparation for Route Server support.
1090 ** "no neighbor PEER" command is added. You can delete neighbor
1091 without specifying AS number.
1093 ** "no neighbor ebgp-multihop" command is added.
1095 ** "no neighbor port PORT" command is added.
1097 ** To conform RFC1771, "neighbor PEER send-community" is default

1099 please specify "no neighbor PEER send-community" to the peer.
1101 ** "neighbor maximum-prefix NUMBER" command is added.
1103 ** Multi-protocol extention NLRI is proceeded only when the peer is
1104 configured proper Address Family and Subsequent Address Family. If
1105 not, those NLRI are simply ignored.
1107 ** Aggregate-address support is improved. Currently below commands
1111 "aggregate-address summary-only"
1112 "no aggregate-address"
1113 "no aggregate-address summary-only"
1115 "ipv6 bgp aggregate-address"
1116 "ipv6 bgp aggregate-address summary-only"
1117 "no ipv6 bgp aggregate-address"
1118 "no ipv6 bgp aggregate-address summary-only"
1120 ** redistribute route-map bug is fixed.
1122 ** MBGP support becomes default. "configure" option --enable-mbgp is
1125 ** New command "neighbor PEER timers connect <1-65535>" is added.
1127 ** New command "neighbor PEER override-capability" is added.
1129 ** New command "show ip bgp neighbor A.B.C.D advertised-route" is added.
1131 ** New command "show ip bgp neighbor A.B.C.D routes" is added. To use
1132 this command, you have to configure neighbor with
1133 "neighbor A.B.C.D soft-reconfiguration inbound" beforehand.
1136 * Changes in zebra-0.83
1140 ** Serious bug fix about fetching global and link-local address at the
1141 same time. Due to this bug, corrupted IPv6 prefix is generated. If
1142 you uses bgpd for BGP-4+ please update to this version. The bug is
1143 introduced in zebra-0.82.
1145 ** When bgpd send Notify message, don't use thread manager. It is now
1146 send to neighbor immediately.
1148 * Changes in zebra-0.82
1150 ** Solaris 2.6 support is added by Michael Handler
1151 <handler@sub-rosa.com>.
1153 ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>.
1154 Please specify --enable-mbgp to configure script. This option will be
1155 removed in the future and MBGP support will be default.
1159 ** When interface goes down, withdraw connected routes from routing
1160 table. When interface goes up, restore the routes to the routing
1163 ** `show interface' show interface's statistics on Linux and BSD with
1166 ** Now zebra can get MTU value on BSDI/OS.
1170 ** Add capability option support based upon
1171 draft-ietf-idr-bgp4-cap-neg-04.txt.
1173 ** Add `show ipv6 bgp prefix-list' command.
1175 ** Check self AS appeared in received routes.
1177 ** redistribute route-map support is added.
1179 ** BGP packet dump feature compatible with MRT.
1183 ** Fix bug of `timers basic' command's argument format.
1187 ** Calculate max RTE using interface's MTU value.
1191 ** Some correction to LSU processing.
1193 ** Add check for lsa->refresh_list.
1197 ** Many debug feature is added.
1199 * Changes in zebra-0.81
1201 ** SNMP support is disabled in default.--enable-snmp option is added
1202 to configure script.
1206 ** Fix FSM bug which introduced in zebra-0.80.
1208 * Changes in zebra-0.80
1212 New access-list name space `ipv6 access-list' is added. At the same
1213 time, `access-list' statemant only accepts IPv4 prefix. Please be
1214 careful if you use IPv6 filtering. You will need to change your
1215 configuration. For IPv6 filtering please use `ipv6 access-list'.
1217 As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
1221 access-list DML-net permit 203.181.89.0/24
1222 access-list DML-net permit 3ffe:506::0/32
1223 access-list DML-net deny any
1226 Above configuration is not valid for zebra-08x. Please add `ipv6'
1227 before 'access-list' when you configure IPv6 filtering.
1230 access-list DML-net permit 203.181.89.0/24
1231 access-list DML-net deny any
1233 ipv6 access-list DML-net permit 3ffe:506::0/32
1234 ipv6 access-list DML-net deny any
1239 And also new prefix-list name space `ipv6 prefix-list' is added. It
1240 is the same as the change of `access-list'. `ip prefix-list' now only
1241 accept IPv4 prefix. It was source of confusion that `ip prefix-list'
1242 can be used both IPv4 and IPv6 filtering. Now name space is separated
1243 to clear the meaning of the filter.
1245 If you use `ip prefix-list' for IPv6 filtering, please change the
1249 ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1250 ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1251 ip prefix-list 6bone-filter seq 12 deny 3ffe::/16
1252 ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1253 ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1254 ip prefix-list 6bone-filter seq 30 deny any
1257 Now user can explicitly configure it as IPv6 prefix-list.
1260 ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1261 ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1262 ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16
1263 ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1264 ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1265 ipv6 prefix-list 6bone-filter seq 30 deny any
1270 If you want to filter only default route (0.0.0.0/0) and permit other
1271 routes, it was hard to do that. Now `ip prefix-list' can be used for
1272 RIP route filtering.
1276 `distribute-list prefix PLIST_NAME (in|out) IFNAME'
1278 is added to ripd. So you can configure on eth0 interface accept all
1279 routes other than default routes.
1283 distribute-list prefix filter-default in eth0
1285 ip prefix-list filter-default deny 0.0.0.0/0 le 0
1286 ip prefix-list filter-default permit any
1289 * RIPng configuration
1291 Same change is done for ripngd. You can use `ipv6 prefix-list' for
1296 distribute-list prefix filter-default in eth0
1298 ipv6 prefix-list filter-default deny ::/0 le 0
1299 ipv6 prefix-list filter-default permit any
1304 So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
1305 done with traditional IPv4 peering statement like blow.
1309 neighbor 3ffe:506::1 remote-as 2500
1310 neighbor 3ffe:506::1 prefix-list 6bone-filter out
1313 For separating configuration IPv4 and IPv6, and for retaining Cisco
1314 configuration compatibility, now IPv6 configuration is done by IPv6
1315 specific statement. IPv6 BGP configuration is done by statement which
1316 start from `ipv6 bgp'.
1321 ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
1322 ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
1325 At the same time some IPv6 specific commands are deleted from IPv4
1328 o redistribute ripng
1329 o redistribute ospf6
1330 o neighbor PEER version BGP_VERSION
1331 o neighbor PEER interface IFNAME
1333 Those commands are only accepted as like below.
1335 o ipv6 bgp redistribute ripng
1336 o ipv6 bgp redistribute ospf6
1337 o ipv6 bgp neighbor PEER version BGP_VERSION
1338 o ipv6 bgp neighbor PEER interface IFNAME
1340 And below new commands are added.
1342 o ipv6 bgp network IPV6_PREFIX
1343 o ipv6 bgp redistribute static
1344 o ipv6 bgp redistribute connected
1345 o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
1346 o ipv6 bgp neighbor PEER ebgp-multihop [TTL]
1347 o ipv6 bgp neighbor PEER description DESCRIPTION
1348 o ipv6 bgp neighbor PEER shutdown
1349 o ipv6 bgp neighbor PEER route-reflector-client
1350 o ipv6 bgp neighbor PEER update-source IFNAME
1351 o ipv6 bgp neighbor PEER next-hop-self
1352 o ipv6 bgp neighbor PEER timers holdtime <0-65535>
1353 o ipv6 bgp neighbor PEER timers keepalive <0-65535>
1354 o ipv6 bgp neighbor PEER send-community
1355 o ipv6 bgp neighbor PEER weight <0-65535>
1356 o ipv6 bgp neighbor PEER default-originate
1357 o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out)
1358 o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
1359 o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
1360 o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
1362 And some utility commands are introduced.
1364 o clear ipv6 bgp [PEER]
1365 o show ipv6 bgp neighbors [PEER]
1366 o show ipv6 bgp summary
1368 I hope these changes are easy to understand for current Zebra users...
1370 * To restrict connection to VTY interface.
1372 It used to be both IPv4 and IPv6 filter can be specified with one
1373 access-list. Then the access-list can be appried to VTY interface
1374 with `access-class' stetement in `line vty' node. Below is example in
1378 access-list local-only permit 127.0.0.1/32
1379 access-list local-only permit ::1/128
1380 access-list local-only deny any
1383 access-class local-only
1386 Now IPv4 and IPv6 filter have each name space. It is not possible to
1387 specify IPv4 and IPv6 filter with one access-list. For setting IPv6
1388 access-list in `line vty', `ipv6 access-class' statement is
1389 introduced. Let me show the configuration in zebra-0.8x.
1392 access-list local-only permit 127.0.0.1/32
1393 access-list local-only deny any
1395 ipv6 access-list local-only permit ::1/128
1396 ipv6 access-list local-only dny any
1399 access-class local-only
1400 ipv6 access-class local-only
1405 New IPv6 related route-map match commands are added.
1407 o match ipv6 address
1408 o match ipv6 next-hop
1410 Please change your configuration if you use IP match statement for
1416 access-list all permit any
1418 route-map set-nexthop permit 10
1419 match ip address all
1420 set ipv6 next-hop global 3ffe:506::1
1421 set ipv6 next-hop local fe80::cbb5:591a
1427 ipv6 access-list all permit any
1429 route-map set-nexthop permit 10
1430 match ipv6 address all
1431 set ipv6 next-hop global 3ffe:506::1
1432 set ipv6 next-hop local fe80::cbb5:591a
1437 Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
1438 when the connection fail. Those daemons try to connect zebra every 10
1439 seconds first three trial, then the interval changed to 60 seconds.
1440 After all, if ten connections are fail, protocol daemon give up the
1441 connection to the zebra daemon.
1443 * SNMP support (is not yet finished)
1445 Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
1446 agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
1447 and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
1448 compiled with ucd-snmp-3.6.2.
1450 After applying the patch to ucd-snmp-4.0.1, please configure it with
1453 % configure --with-mib-modules=smux
1455 After compile & install ucd-snmp-4.0.1, you will need to configure
1456 smuxpeer. I'm now using below configuration.
1458 /usr/local/share/snmp/snmpd.conf
1459 ================================
1460 smuxpeer 1.3.6.1.6.3.1 test
1462 Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard
1463 coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP.
1465 * HUP signal treatment
1467 From zebra-0.80, ripd will reload it's configuration file when ripd
1468 receives HUP signal. Other daemon such as bgpd, ospfd will support
1469 HUP signal treatment soon.
1471 * Changes in zebra-0.79
1475 ** Broadcast address setting on Linux box bug is fixed.
1477 ** Protocol daemon can install connected IPv6 route into the kernel.

1521 ** Interface information protocol is changed. Now interface
1522 addition/deletion and interface's address addition/deletion is
1527 ** BGP hold timer bug is fixed.
1529 ** BGP keepavlie timer becomes configurable.
1533 ** When making reply to rip's REQUEST message, fill in
1534 RIP_METRIC_INFINITY with network byte order using htonl ().
1536 ** Pass host byte order address to IN_CLASSC and IN_CLASSB macro.
1540 ** LSA flooding works.
1542 ** Fix bug of DD processing.
1544 ** Fix bug of originating router-LSA bug is fixed.
1546 ** LSA structure is changed to support LSA aging.

1565 ** Basic IPv6 router advertisement codes added. It is not yet usable.
1567 ** Fix IPv6 route addition/deletion bug is fixed.
1569 ** `show ip route A.B.C.D' works
1573 ** When invalid unfeasible routes length comes, bgpd send notify then
1574 continue to process the packet. Now bgpd stop parsing invalid packet
1575 then return to main loop.
1577 ** BGP-4+ withdrawn routes parse bug is fixed.
1579 ** When BGP-4+ information passed to non shared network's peer, trim
1580 link-local next-hop information.
1582 ** `no redistribute ROUTE_TYPE' withdraw installed routes from BGP
