3 * Changes in Quagga 0.99.23
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.
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
27 * Changes in Quagga 0.99.22
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.
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
44 * Changes in Quagga 0.99.21
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
56 * Changes in Quagga 0.99.10
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.
61 - [bgpd] Added new route-map set statement: "as-path exclude"
62 - Zebra RIB updates queue has evolved into a multi-level
63 structure to address RIB consistency issues.
65 * Changes in Quagga 0.99.2
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.
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.
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
81 - Solaris least privileges support added.
83 * Changes in Quagga 0.99.1
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.
89 - 'show thread cpu' now displays both cpu+system and wall-clock time,
90 where getrusage() is available.
92 - Background threads added and workqueue API added, with a
93 'show work-queues' command. Thread scheduling improved slightly.
95 - Zebra now has a work-queue for RIB processing. See 'show work-queues' in
98 - Support for interface renaming on Linux netlink systems.
100 - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip
101 route-source" command.
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.
107 * Changes in Quagga 0.98.0
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.
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.
118 - BGP route-server support added. See the texinfo documentation.
120 - OSPF API initialisation is disabled by default even if compiled in. You
121 can enable it with -a/--apiserver command line switch.
123 - "write-config integrated" vtysh command replaced with "service
124 integrated-vtysh-config" command.
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.
131 - "secondary" keyword is removed from ip address configuration. All
132 supported OS'es have their own vision what's secondary address and
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.
139 - All libraries are built and used shared, on platforms where libtool
140 supports shared libraries.
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"
146 "ipv6 nd prefix X:X:X:X::/X"
148 All router advertisement options are documented in texi documentation.
150 - --enable-nssa configure switch is removed. NSSA support is stable enough.
152 - Daemons don't look at current directory for config file any more.
154 * Changes in Quagga 0.96.5
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>
160 - New option --enable-exampledir puts example files in a separate
161 directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules
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.
168 - Import current CVS isisd from SourceForge, then merge it with
169 the Quagga's Framework.
171 * Changes in Quagga 0.96.4
173 - Further fixes to ospfd, some relating to the PtP revert. Interface
174 lookups should be a lot more robust now.
176 - Fix for a remote triggerable crash in vty layer.
178 - Improvements to ripd, and addition of split horizon support.
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.
184 * Changes in Quagga 0.96.3
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.
190 * Changes in Quagga 0.96.2
194 * Changes in Quagga 0.96.1
196 - Iron out problem with the privileges definitions
198 * Changes in Quagga 0.96
200 - Privilege support, daemons now run with the minimal privileges needed, see
201 the documentation for details.
203 - NSSA ABR support in ospfd.
205 - OSPF-API support merged in.
207 - 6WIND patch merged in.
209 * Changes in zebra-0.93
213 ** Configuration is changed to new format.
217 ** Crush bugs which reported on Zebra ML is fixed.

243 * Changes in zebra-0.92
245 ** Overall security is improved. Default umask is 0077.
249 ** If output interface is in simple password authentication mode,
250 substruct one from rtemax.
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.
265 bgp router-id 10.0.0.1

342 ** IPv6 IBGP nexthop change is monitored.
344 ** Unknown transitive attribute is passed with partial flag bit on.
348 ** Fix bug of LSA MaxAge flood.
350 ** Fix bug of NSSA codes.
352 * Changes in zebra-0.90
354 ** From this beta release, --enable-unixdomain and --enable-newrib
355 becomes default. So both options are removed from configure.in. To
356 revert old behavior please specify below option.
358 --enable-tcp-zebra # TCP/IP socket is used for protocol daemon and zebra.
359 --enable-oldrib # Turn on old RIB implementation.
361 Old RIB implementation will be removed in zebra-0.91.
363 ** From this beta release --enable-multipath is supported. This
364 option is only effective on GNU/Linux kernel with
365 CONFIG_IP_ADVANCED_ROUTER and CONFIG_IP_ROUTE_MULTIPATH is set.
367 --enable-multipath=ARG # ARG must be digit. When ARG is 0 unlimit multipath number.
369 ** From this release we do not include guile files.
373 ** newlist.[ch] is merged with linklist.[ch].
375 ** Now Zebra works on MacOS X public beta.
377 ** Access-list can have remark. "access-list WORD remark LINE" define
378 remark for specified access-list.
380 ** Key of key-chain is sorted by it's idetifier value.
382 ** prefix-list rule is slightly changed. The rule of "len <= ge-value
383 <= le-value" is changed to "len < ge-value <= le-value".
385 ** According to above prefix-list rule change, add automatic
386 conversion function of an old rule. ex.) 10.0.0.0/8 ge 8 -> 10.0.0.0/8
389 ** SMUX can handle SNMP trap.
391 ** In our event library, event thread is executed before any other

394 ** Robust method for writing configuration file and recover from
395 backing up config file.
397 ** Display "end" at the end of configuration.
399 ** Fix memory leak in vtysh_read().
401 ** Fix memroy leak about access-list and prefix-list name.
405 ** UNIX domain socket server of zebra protocol is added.
407 ** Fix PointoPoint interface network bug. The destination network
408 should be installed into routing table instead of local network.
410 ** Metric value is reflected to kernel routing table.
412 ** "show ip route" display uptime of RIP,OSPF,BGP routes.
414 ** New RIB implementation is added.
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
420 *** Static route with distance value
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.
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>
429 If the least distance value's route's nexthop are unreachable,
430 select the least distance value route which has reachable nexthop is
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
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
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
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.
448 ip route 1.1.1.1/32 ppp0
450 When ppp0 comes up, the route is installed properly.
452 *** Multiple nexthop routes for one prefix
454 Multiple nexthop routes can be specified for one prefix. Even the
455 kernel support only one nexthop for one prefix user can configure
458 When you configure routes like below, prefix 10.0.0.1 has three
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
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.
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
473 '*' means this nexthop is installed into the kernel.
475 *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
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
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
489 S>* 10.0.0.1/32 [1/0] via 10.0.0.2
491 is directly connected, eth0
493 *** Kernel message delete installed route.
495 After zebra install static or dynamic route into the kernel.
497 R>* 0.0.0.0/0 [120/3] via 10.0.0.1
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.
503 ** GNU/Linux netlink socket handling is improved to fix race condition
504 between kernel message and user command responce.
508 ** Add show neighbor's routes command.
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"
515 ** BGP passive peer support problem is fixed.
517 ** Redistributed IGP nexthop is passed to BGP nexthop.
519 ** On multiaccess media, if the nexthop is reachable nexthop is passed
522 ** Remove zebra-0.88 compatibility commands.
524 "match ip prefix-list WORD"
525 "match ipv6 prefix-list WORD"
527 Instead of above please use below commands.
529 "match ip address prefix-list WORD"
530 "match ipv6 address prefix-list WORD"
532 ** Fix bug of holdtimer is not reset when bgp cleared.
534 ** "show ip bgp summary" display peer establish/drop count.
536 ** Change "match ip next-hop" argument from IP address to access-list
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.
542 ** New route-map command "set community-delete COMMUNITY-LIST" is
543 added. Community matched the CoMMUNITY-LIST is removed from the
546 ** BGP-MIB implementation is finished.
548 ** When BGP connection comes from unconfigured IP address, close
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.
555 ** Add "bgp bestpath as-path ignore" command. When this option is
556 set, do not concider AS path length when route selection.
558 ** Add "bgp bestpath compare-routerid". When this option is set,
559 compare router ID when the routes comes from EBGP peer.
561 ** Add "bgp deterministic-med" process.
563 ** BGP flap dampening feature is added.
565 ** When IBGP nexthop is changed, it is reflected to RIB.
567 ** Change "neighbor route-refresh" command to "neighbor capability
572 ** Change "match ip next-hop" argument from IP address to access-list
575 ** "no ip rip (send|receive)" command accept version number argument.
577 ** Memory leak related classfull network generation is fixed.
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
587 ** Fix bug of refreshing default route.
589 ** --enable-nssa turn on undergoing NSSA feature.
591 ** Fix bug of Hello packet's option is not properly set when interface
594 ** Reduce unconditional logging.
596 ** Add nexthop to OSPF path only when it is not there.
598 ** When there is no DR on network (suppose you have only one router
599 with interface priority 0). It's router LSA does not contain the link
600 information about this network.
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.
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
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
618 ** Virtual link can not configured in stub area.
620 ** Clear a ls_upd_queue queue of the interface when interface goes
623 ** "no router ospf" unregister redistribution requests from zebra.
625 ** New command for virtual-link configuration is added.
627 "area A.B.C.D virtual-link A.B.C.D"
628 "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>"

631 "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"
632 "area A.B.C.D virtual-link A.B.C.D message-digest-key <1-255> md5 KEY"
634 ** Clear cryptographic sequence number when neighbor status is changed
637 ** Make Summary LSA's origination and refreshment as same as other
640 ** New OSPF pakcet read method. Now maximum packet length may be 65535
641 bytes (maximum IP packet length).
643 ** Checking the age of the found LSA and if the LSA is MAXAGE we
644 should call refresh instead of originate.
646 ** Install multipath information to zebra.
648 ** Fix socket descriptor leak when system call failed.
652 ** Whole functionality has been rewritten as new code. new command
653 "show ipv6 ospf6 spf node", "show ipv6 ospf6 spf tree", "show ipv6
654 ospf6 spf table" has been added.
656 ** Change to do not send garbage route whose nexthop is not linklocal
659 ** "redistribute ospf6" was generated in "router ospf6" in config
662 ** LSDB sync bug is fixed.
664 ** Fix bug of using unavailable route.
668 ** route-map and access-list configuration is merged into one
671 ** /usr/local/etc/Zebra.conf is integrated configuration file. "write
672 memory" in vtysh will write whole configuration to this file.
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
677 empty then invoke all daemon. After that vtysh -b will setup saved

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.
1137 DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>")
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.
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.
1149 ** "terminal monitor" command is added. "no terminal monitor" is for
1150 disabling. This command simply display logging information to the
1153 ** dropline.[ch] files are deleted.
1157 ** BGP neighbor configuration are sorted by it's IP address.
1159 ** BGP peer configuration and actual peer is separated. This is
1160 preparation for Route Server support.
1162 ** "no neighbor PEER" command is added. You can delete neighbor

1165 ** "no neighbor ebgp-multihop" command is added.
1167 ** "no neighbor port PORT" command is added.
1169 ** To conform RFC1771, "neighbor PEER send-community" is default

1171 please specify "no neighbor PEER send-community" to the peer.
1173 ** "neighbor maximum-prefix NUMBER" command is added.
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.
1179 ** Aggregate-address support is improved. Currently below commands
1183 "aggregate-address summary-only"
1184 "no aggregate-address"
1185 "no aggregate-address summary-only"
1187 "ipv6 bgp aggregate-address"
1188 "ipv6 bgp aggregate-address summary-only"

1201 ** New command "show ip bgp neighbor A.B.C.D advertised-route" is added.
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.
1208 * Changes in zebra-0.83
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.
1217 ** When bgpd send Notify message, don't use thread manager. It is now
1218 send to neighbor immediately.
1220 * Changes in zebra-0.82
1222 ** Solaris 2.6 support is added by Michael Handler
1223 <handler@sub-rosa.com>.
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.
1231 ** When interface goes down, withdraw connected routes from routing
1232 table. When interface goes up, restore the routes to the routing

1247 ** Check self AS appeared in received routes.
1249 ** redistribute route-map support is added.
1251 ** BGP packet dump feature compatible with MRT.
1255 ** Fix bug of `timers basic' command's argument format.
1259 ** Calculate max RTE using interface's MTU value.
1263 ** Some correction to LSU processing.
1265 ** Add check for lsa->refresh_list.
1269 ** Many debug feature is added.
1271 * Changes in zebra-0.81
1273 ** SNMP support is disabled in default.--enable-snmp option is added
1274 to configure script.
1278 ** Fix FSM bug which introduced in zebra-0.80.
1280 * Changes in zebra-0.80
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'.
1289 As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
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
1298 Above configuration is not valid for zebra-08x. Please add `ipv6'
1299 before 'access-list' when you configure IPv6 filtering.
1302 access-list DML-net permit 203.181.89.0/24
1303 access-list DML-net deny any
1305 ipv6 access-list DML-net permit 3ffe:506::0/32
1306 ipv6 access-list DML-net deny any
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.
1317 If you use `ip prefix-list' for IPv6 filtering, please change the
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
1329 Now user can explicitly configure it as IPv6 prefix-list.
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
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.
1348 `distribute-list prefix PLIST_NAME (in|out) IFNAME'
1350 is added to ripd. So you can configure on eth0 interface accept all
1351 routes other than default routes.
1355 distribute-list prefix filter-default in eth0
1357 ip prefix-list filter-default deny 0.0.0.0/0 le 0
1358 ip prefix-list filter-default permit any
1361 * RIPng configuration
1363 Same change is done for ripngd. You can use `ipv6 prefix-list' for
1368 distribute-list prefix filter-default in eth0
1370 ipv6 prefix-list filter-default deny ::/0 le 0
1371 ipv6 prefix-list filter-default permit any
1376 So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
1377 done with traditional IPv4 peering statement like blow.
1381 neighbor 3ffe:506::1 remote-as 2500
1382 neighbor 3ffe:506::1 prefix-list 6bone-filter out
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'.
1393 ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
1394 ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
1397 At the same time some IPv6 specific commands are deleted from IPv4
1400 o redistribute ripng
1401 o redistribute ospf6
1402 o neighbor PEER version BGP_VERSION
1403 o neighbor PEER interface IFNAME
1405 Those commands are only accepted as like below.
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
1412 And below new commands are added.
1414 o ipv6 bgp network IPV6_PREFIX
1415 o ipv6 bgp redistribute static
1416 o ipv6 bgp redistribute connected
1417 o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]

1426 o ipv6 bgp neighbor PEER send-community
1427 o ipv6 bgp neighbor PEER weight <0-65535>
1428 o ipv6 bgp neighbor PEER default-originate
1429 o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out)
1430 o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
1431 o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
1432 o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
1434 And some utility commands are introduced.
1436 o clear ipv6 bgp [PEER]
1437 o show ipv6 bgp neighbors [PEER]
1438 o show ipv6 bgp summary
1440 I hope these changes are easy to understand for current Zebra users...
1442 * To restrict connection to VTY interface.
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
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
1455 access-class local-only
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.
1464 access-list local-only permit 127.0.0.1/32
1465 access-list local-only deny any
1467 ipv6 access-list local-only permit ::1/128
1468 ipv6 access-list local-only dny any
1471 access-class local-only
1472 ipv6 access-class local-only
1477 New IPv6 related route-map match commands are added.
1479 o match ipv6 address
1480 o match ipv6 next-hop
1482 Please change your configuration if you use IP match statement for
1488 access-list all permit any
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
1499 ipv6 access-list all permit any
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
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.
1515 * SNMP support (is not yet finished)
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
