1 * Changes in Quagga 0.98.0
3 - Watchquagga daemon added. This is not well tested yet. Please try
4 monitor mode first before enabling restart features. It is important
5 to make sure that the various timers are configured with appropriate
8 - BGP route-server support added. See the texinfo documentation.
10 - OSPF API initialisation is disabled by default even if compiled in. You
11 can enable it with -a/--apiserver command line switch.
13 - "write-config integrated" vtysh command replaced with "service
14 integrated-vtysh-config" command.
16 - Router id is now handled by zebra daemon and all daemons receive changes
17 from it. Router id can be overriden in daemons' configurations of course.
18 To fix common router id in zebra daemon you can either install non-127
19 address on loopback or use "router-id x.x.x.x" command.
21 - "secondary" keyword is removed from ip address configuration. All
22 supported OS'es have their own vision what's secondary address and
25 - Zebra no longer enables forwarding by default. If you rely on zebra to
26 enable forwarding make sure to add '<ip|ip6> forwarding' statements
27 to your zebra configuration file.
29 - All libraries are built and used shared, on platforms where libtool
30 supports shared libraries.
32 - Router advertisement syntax is changed. In usual cases (if you didn't do
33 any fancy stuff) it's enough to change lines in configuration from:
34 "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link"
36 "ipv6 nd prefix X:X:X:X::/X"
38 All router advertisement options are documented in texi documentation.
40 - --enable-nssa configure switch is removed. NSSA support is stable enough.
42 - Daemons don't look at current directory for config file any more.
44 * Changes in Quagga 0.96.5
46 - include files are installed in $(prefix)/include/quagga. Programs
47 building against these includes should -I$(prefix)/include and e.g.
48 #include <quagga/routemap.h>
50 - New option --enable-exampledir puts example files in a separate
51 directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules
54 - New configure options --enable-configfile-mask and
55 --enable-logfile-mask to set umask values for config and log
56 values. Masks default to 0600, matching previous behavior.
58 - Import current CVS isisd from SourceForge, then merge it with
59 the Quagga's Framework.
61 * Changes in Quagga 0.96.4
63 - Further fixes to ospfd, some relating to the PtP revert. Interface
64 lookups should be a lot more robust now.
66 - Fix for a remote triggerable crash in vty layer.
68 - Improvements to ripd, and addition of split horizon support.
70 - Improved bgpd table support, now dumps at time of day intervals rather
71 than time from startup intervals. Much improved support for IPv6 table
72 dumps. show commands for views improved.
74 * Changes in Quagga 0.96.3
76 - revert the 'generic PtP' patch. Means Quagga will no longer work with
77 FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs
78 which the PtP patch introduced.
80 * Changes in Quagga 0.96.2
84 * Changes in Quagga 0.96.1
86 - Iron out problem with the privileges definitions
88 * Changes in Quagga 0.96
90 - Privilege support, daemons now run with the minimal privileges needed, see
91 the documentation for details.
93 - NSSA ABR support in ospfd.
95 - OSPF-API support merged in.
97 - 6WIND patch merged in.
99 * Changes in zebra-0.93
103 ** Configuration is changed to new format.
107 ** Crush bugs which reported on Zebra ML is fixed.
109 ** Opaque LSA and TE LSA support is added by KDD R&D Laboratories,
114 ** Many bugs are fixed.

125 route-reflector-client
127 soft-reconfiguration inbound
131 ** Treat kernel type routes as EGP routes.
133 * Changes in zebra-0.92
135 ** Overall security is improved. Default umask is 0077.
139 ** If output interface is in simple password authentication mode,
140 substruct one from rtemax.
144 ** IPv4 multicast and IPv6 unicast configuration is changed to so
145 called new config. All of AFI and SAFI specific configuration is
146 moved to "address-family" node. When you have many IPv6 only
147 configuration, you will see many "no neighbor X:X::X:X activate" line
148 in your configuration to disable IPv4 unicast NLRI exchange. In that
149 case please use "no bgp default ipv4-unicast" command to suppress the
150 output. Until zebra-0.93, old config is still left for compatibility.

232 ** IPv6 IBGP nexthop change is monitored.
234 ** Unknown transitive attribute is passed with partial flag bit on.
238 ** Fix bug of LSA MaxAge flood.
240 ** Fix bug of NSSA codes.
242 * Changes in zebra-0.90
244 ** From this beta release, --enable-unixdomain and --enable-newrib
245 becomes default. So both options are removed from configure.in. To
246 revert old behavior please specify below option.
248 --enable-tcp-zebra # TCP/IP socket is used for protocol daemon and zebra.
249 --enable-oldrib # Turn on old RIB implementation.
251 Old RIB implementation will be removed in zebra-0.91.
253 ** From this beta release --enable-multipath is supported. This
254 option is only effective on GNU/Linux kernel with
255 CONFIG_IP_ADVANCED_ROUTER and CONFIG_IP_ROUTE_MULTIPATH is set.
257 --enable-multipath=ARG # ARG must be digit. When ARG is 0 unlimit multipath number.
259 ** From this release we do not include guile files.
263 ** newlist.[ch] is merged with linklist.[ch].
265 ** Now Zebra works on MacOS X public beta.
267 ** Access-list can have remark. "access-list WORD remark LINE" define
268 remark for specified access-list.
270 ** Key of key-chain is sorted by it's idetifier value.
272 ** prefix-list rule is slightly changed. The rule of "len <= ge-value
273 <= le-value" is changed to "len < ge-value <= le-value".
275 ** According to above prefix-list rule change, add automatic
276 conversion function of an old rule. ex.) 10.0.0.0/8 ge 8 -> 10.0.0.0/8
279 ** SMUX can handle SNMP trap.
281 ** In our event library, event thread is executed before any other

298 should be installed into routing table instead of local network.
300 ** Metric value is reflected to kernel routing table.
302 ** "show ip route" display uptime of RIP,OSPF,BGP routes.
304 ** New RIB implementation is added.
306 Now we have enhanced RIB (routing information base) implementation in
307 zebra. New RIB has many new features and fixed some bugs which exist
310 *** Static route with distance value
312 Static route can be specified with administrative distance. The
313 distance value 255 means it is not installed into the kernel.
314 Default value of distance for static route is 1.
316 ip route A.B.C.D/M A.B.C.D <1-255>
317 ip route A.B.C.D/M IFNAME <1-255>
319 If the least distance value's route's nexthop are unreachable,
320 select the least distance value route which has reachable nexthop is
323 ip route 0.0.0.0/0 10.0.0.1
324 ip route 0.0.0.0/0 11.0.0.1 2
326 In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
327 reachable. The route with nexthop 11.0.0.1 will be installed into
331 S>* 0.0.0.0/0 [2/0] via 11.0.0.1
332 S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
334 If the nexthop is unreachable "inactive" is displayed. You can
335 specify any string to IFNAME. There is no need of the interface is
336 there when you configure the route.
338 ip route 1.1.1.1/32 ppp0
340 When ppp0 comes up, the route is installed properly.
342 *** Multiple nexthop routes for one prefix
344 Multiple nexthop routes can be specified for one prefix. Even the
345 kernel support only one nexthop for one prefix user can configure
348 When you configure routes like below, prefix 10.0.0.1 has three
351 ip route 10.0.0.1/32 10.0.0.2
352 ip route 10.0.0.1/32 10.0.0.3
353 ip route 10.0.0.1/32 eth0
355 If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
356 is reachable, then the last route is installed into the kernel.
359 S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
360 via 10.0.0.3 inactive
361 * is directly connected, eth0
363 '*' means this nexthop is installed into the kernel.
365 *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
367 When the kernel support multipath, zebra can install multipath
368 routes into the kernel. Before doing that please make it sure that
369 setting --enable-multipath=ARG to configure script. ARG must be digit
370 value. When specify 0 to ARG, there is no limitation of the number
371 of the multipath. Currently only GNU/Linux with netlink interface is
374 ip route 10.0.0.1/32 10.0.0.2
375 ip route 10.0.0.1/32 10.0.0.3
376 ip route 10.0.0.1/32 eth0
379 S>* 10.0.0.1/32 [1/0] via 10.0.0.2
381 is directly connected, eth0
383 *** Kernel message delete installed route.
385 After zebra install static or dynamic route into the kernel.
387 R>* 0.0.0.0/0 [120/3] via 10.0.0.1
389 If you delete this route outside zebra, old zebra does not reinstall
390 route again. Now the route is re-processed and properly reinstall the
391 static or dynamic route into the kernel.
393 ** GNU/Linux netlink socket handling is improved to fix race condition
394 between kernel message and user command responce.
398 ** Add show neighbor's routes command.
400 "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes"
401 "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes"
402 "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes"
403 "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes"
405 ** BGP passive peer support problem is fixed.
407 ** Redistributed IGP nexthop is passed to BGP nexthop.
409 ** On multiaccess media, if the nexthop is reachable nexthop is passed
412 ** Remove zebra-0.88 compatibility commands.
414 "match ip prefix-list WORD"
415 "match ipv6 prefix-list WORD"
417 Instead of above please use below commands.
419 "match ip address prefix-list WORD"
420 "match ipv6 address prefix-list WORD"
422 ** Fix bug of holdtimer is not reset when bgp cleared.
424 ** "show ip bgp summary" display peer establish/drop count.
426 ** Change "match ip next-hop" argument from IP address to access-list
429 ** When "bgp enforce-first-as" is enabled, check EBGP peer's update
430 has it's AS number in the first AS number in AS sequence.
432 ** New route-map command "set community-delete COMMUNITY-LIST" is
433 added. Community matched the CoMMUNITY-LIST is removed from the
436 ** BGP-MIB implementation is finished.
438 ** When BGP connection comes from unconfigured IP address, close
441 ** Do not compare router ID when the routes comes from EBGP peer.
442 When originator ID is same, take shorter cluster-list route. If
443 cluster-list is same take smaller IP address neighbor's route.
445 ** Add "bgp bestpath as-path ignore" command. When this option is
446 set, do not concider AS path length when route selection.
448 ** Add "bgp bestpath compare-routerid". When this option is set,
449 compare router ID when the routes comes from EBGP peer.
451 ** Add "bgp deterministic-med" process.
453 ** BGP flap dampening feature is added.
455 ** When IBGP nexthop is changed, it is reflected to RIB.
457 ** Change "neighbor route-refresh" command to "neighbor capability
462 ** Change "match ip next-hop" argument from IP address to access-list
465 ** "no ip rip (send|receive)" command accept version number argument.
467 ** Memory leak related classfull network generation is fixed.
469 ** When a route is in garbage collection process (invalid with metric
470 16) and a router receives the same route with valid metric then route
471 was not installed into zebra rib, but only into ripd rib. Moreover ,
472 it will never get into zebra rib, because ripd wrongly assumes it's
477 ** Fix bug of refreshing default route.
479 ** --enable-nssa turn on undergoing NSSA feature.
481 ** Fix bug of Hello packet's option is not properly set when interface
484 ** Reduce unconditional logging.
486 ** Add nexthop to OSPF path only when it is not there.
488 ** When there is no DR on network (suppose you have only one router
489 with interface priority 0). It's router LSA does not contain the link
490 information about this network.
492 ** When you change a priority of interface from/to 0
493 ISM_NeighborChange event should be scheduled in order to elect new
494 DR/BDR on the network.
496 ** When we add some LSA into retransmit list we need to check whether
497 the present old LSA in retransmit list is not more recent than the new
500 ** In states Loading and Full the slave must resend its last Database
501 Description packet in response to duplicate Database Description
502 packets received from the master. For this reason the slave must wait
503 RouterDeadInterval seconds before freeing the last Database
504 Description packet. Reception of a Database Description packet from
505 the master after this interval will generate a SeqNumberMismatch
506 neighbor event. RFC2328 Section 10.8
508 ** Virtual link can not configured in stub area.
510 ** Clear a ls_upd_queue queue of the interface when interface goes
513 ** "no router ospf" unregister redistribution requests from zebra.
515 ** New command for virtual-link configuration is added.
517 "area A.B.C.D virtual-link A.B.C.D"
518 "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>"
519 "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"

564 ** When -b option is specified to vtysh, vtysh read
565 /usr/local/etc/Zebra.conf file then pass the confuguration to proper
566 protocol daemon. So make all protocol daemon's configuration file
567 empty then invoke all daemon. After that vtysh -b will setup saved

1019 * Changes in zebra-0.84
1023 ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada
1024 <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address,
1025 "X:X::X:X/M" for IPv6 prefix. You can use it like this.
1027 DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>")
1029 ** VTY configuration is locked during configuration. This is for
1030 avoiding unconditional crush from two terminals modify the
1031 configuration at the same time. "who" command shows which termnal
1032 lock the configuration. VTY which has '*' character at the head of
1033 line is locking the configuration.
1035 ** Old logging functions are removed. Functions like
1036 log_open,log_close,openlog are deleted. Instead of that please use
1037 zlog_* functions. zvlog_* used in ospf6d are deleted also.
1039 ** "terminal monitor" command is added. "no terminal monitor" is for
1040 disabling. This command simply display logging information to the
1043 ** dropline.[ch] files are deleted.
1047 ** BGP neighbor configuration are sorted by it's IP address.
1049 ** BGP peer configuration and actual peer is separated. This is
1050 preparation for Route Server support.
1052 ** "no neighbor PEER" command is added. You can delete neighbor
1053 without specifying AS number.
1055 ** "no neighbor ebgp-multihop" command is added.
1057 ** "no neighbor port PORT" command is added.
1059 ** To conform RFC1771, "neighbor PEER send-community" is default

1061 please specify "no neighbor PEER send-community" to the peer.
1063 ** "neighbor maximum-prefix NUMBER" command is added.
1065 ** Multi-protocol extention NLRI is proceeded only when the peer is
1066 configured proper Address Family and Subsequent Address Family. If
1067 not, those NLRI are simply ignored.
1069 ** Aggregate-address support is improved. Currently below commands
1073 "aggregate-address summary-only"
1074 "no aggregate-address"
1075 "no aggregate-address summary-only"
1077 "ipv6 bgp aggregate-address"
1078 "ipv6 bgp aggregate-address summary-only"
1079 "no ipv6 bgp aggregate-address"
1080 "no ipv6 bgp aggregate-address summary-only"
1082 ** redistribute route-map bug is fixed.
1084 ** MBGP support becomes default. "configure" option --enable-mbgp is
1087 ** New command "neighbor PEER timers connect <1-65535>" is added.
1089 ** New command "neighbor PEER override-capability" is added.
1091 ** New command "show ip bgp neighbor A.B.C.D advertised-route" is added.
1093 ** New command "show ip bgp neighbor A.B.C.D routes" is added. To use
1094 this command, you have to configure neighbor with
1095 "neighbor A.B.C.D soft-reconfiguration inbound" beforehand.
1098 * Changes in zebra-0.83
1102 ** Serious bug fix about fetching global and link-local address at the
1103 same time. Due to this bug, corrupted IPv6 prefix is generated. If
1104 you uses bgpd for BGP-4+ please update to this version. The bug is
1105 introduced in zebra-0.82.
1107 ** When bgpd send Notify message, don't use thread manager. It is now
1108 send to neighbor immediately.
1110 * Changes in zebra-0.82
1112 ** Solaris 2.6 support is added by Michael Handler
1113 <handler@sub-rosa.com>.
1115 ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>.
1116 Please specify --enable-mbgp to configure script. This option will be
1117 removed in the future and MBGP support will be default.
1121 ** When interface goes down, withdraw connected routes from routing
1122 table. When interface goes up, restore the routes to the routing
1125 ** `show interface' show interface's statistics on Linux and BSD with
1128 ** Now zebra can get MTU value on BSDI/OS.
1132 ** Add capability option support based upon
1133 draft-ietf-idr-bgp4-cap-neg-04.txt.
1135 ** Add `show ipv6 bgp prefix-list' command.
1137 ** Check self AS appeared in received routes.
1139 ** redistribute route-map support is added.
1141 ** BGP packet dump feature compatible with MRT.
1145 ** Fix bug of `timers basic' command's argument format.
1149 ** Calculate max RTE using interface's MTU value.
1153 ** Some correction to LSU processing.
1155 ** Add check for lsa->refresh_list.
1159 ** Many debug feature is added.
1161 * Changes in zebra-0.81
1163 ** SNMP support is disabled in default.--enable-snmp option is added
1164 to configure script.
1168 ** Fix FSM bug which introduced in zebra-0.80.
1170 * Changes in zebra-0.80
1174 New access-list name space `ipv6 access-list' is added. At the same
1175 time, `access-list' statemant only accepts IPv4 prefix. Please be
1176 careful if you use IPv6 filtering. You will need to change your
1177 configuration. For IPv6 filtering please use `ipv6 access-list'.
1179 As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
1183 access-list DML-net permit 203.181.89.0/24
1184 access-list DML-net permit 3ffe:506::0/32
1185 access-list DML-net deny any
1188 Above configuration is not valid for zebra-08x. Please add `ipv6'
1189 before 'access-list' when you configure IPv6 filtering.
1192 access-list DML-net permit 203.181.89.0/24
1193 access-list DML-net deny any
1195 ipv6 access-list DML-net permit 3ffe:506::0/32
1196 ipv6 access-list DML-net deny any
1201 And also new prefix-list name space `ipv6 prefix-list' is added. It
1202 is the same as the change of `access-list'. `ip prefix-list' now only
1203 accept IPv4 prefix. It was source of confusion that `ip prefix-list'
1204 can be used both IPv4 and IPv6 filtering. Now name space is separated
1205 to clear the meaning of the filter.
1207 If you use `ip prefix-list' for IPv6 filtering, please change the
1211 ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1212 ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1213 ip prefix-list 6bone-filter seq 12 deny 3ffe::/16
1214 ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1215 ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1216 ip prefix-list 6bone-filter seq 30 deny any
1219 Now user can explicitly configure it as IPv6 prefix-list.
1222 ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1223 ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1224 ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16
1225 ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1226 ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1227 ipv6 prefix-list 6bone-filter seq 30 deny any
1232 If you want to filter only default route (0.0.0.0/0) and permit other
1233 routes, it was hard to do that. Now `ip prefix-list' can be used for
1234 RIP route filtering.
1238 `distribute-list prefix PLIST_NAME (in|out) IFNAME'
1240 is added to ripd. So you can configure on eth0 interface accept all
1241 routes other than default routes.
1245 distribute-list prefix filter-default in eth0
1247 ip prefix-list filter-default deny 0.0.0.0/0 le 0
1248 ip prefix-list filter-default permit any
1251 * RIPng configuration
1253 Same change is done for ripngd. You can use `ipv6 prefix-list' for
1258 distribute-list prefix filter-default in eth0
1260 ipv6 prefix-list filter-default deny ::/0 le 0
1261 ipv6 prefix-list filter-default permit any
1266 So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
1267 done with traditional IPv4 peering statement like blow.
1271 neighbor 3ffe:506::1 remote-as 2500
1272 neighbor 3ffe:506::1 prefix-list 6bone-filter out
1275 For separating configuration IPv4 and IPv6, and for retaining Cisco
1276 configuration compatibility, now IPv6 configuration is done by IPv6
1277 specific statement. IPv6 BGP configuration is done by statement which
1278 start from `ipv6 bgp'.
1283 ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
1284 ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
1287 At the same time some IPv6 specific commands are deleted from IPv4
1290 o redistribute ripng
1291 o redistribute ospf6
1292 o neighbor PEER version BGP_VERSION
1293 o neighbor PEER interface IFNAME
1295 Those commands are only accepted as like below.
1297 o ipv6 bgp redistribute ripng
1298 o ipv6 bgp redistribute ospf6
1299 o ipv6 bgp neighbor PEER version BGP_VERSION
1300 o ipv6 bgp neighbor PEER interface IFNAME
1302 And below new commands are added.
1304 o ipv6 bgp network IPV6_PREFIX
1305 o ipv6 bgp redistribute static
1306 o ipv6 bgp redistribute connected
1307 o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
1308 o ipv6 bgp neighbor PEER ebgp-multihop [TTL]
1309 o ipv6 bgp neighbor PEER description DESCRIPTION
1310 o ipv6 bgp neighbor PEER shutdown
1311 o ipv6 bgp neighbor PEER route-reflector-client
1312 o ipv6 bgp neighbor PEER update-source IFNAME
1313 o ipv6 bgp neighbor PEER next-hop-self
1314 o ipv6 bgp neighbor PEER timers holdtime <0-65535>
1315 o ipv6 bgp neighbor PEER timers keepalive <0-65535>
1316 o ipv6 bgp neighbor PEER send-community
1317 o ipv6 bgp neighbor PEER weight <0-65535>
1318 o ipv6 bgp neighbor PEER default-originate
1319 o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out)
1320 o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
1321 o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
1322 o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
1324 And some utility commands are introduced.
1326 o clear ipv6 bgp [PEER]
1327 o show ipv6 bgp neighbors [PEER]
1328 o show ipv6 bgp summary
1330 I hope these changes are easy to understand for current Zebra users...
1332 * To restrict connection to VTY interface.
1334 It used to be both IPv4 and IPv6 filter can be specified with one
1335 access-list. Then the access-list can be appried to VTY interface
1336 with `access-class' stetement in `line vty' node. Below is example in
1340 access-list local-only permit 127.0.0.1/32
1341 access-list local-only permit ::1/128
1342 access-list local-only deny any
1345 access-class local-only
1348 Now IPv4 and IPv6 filter have each name space. It is not possible to
1349 specify IPv4 and IPv6 filter with one access-list. For setting IPv6
1350 access-list in `line vty', `ipv6 access-class' statement is
1351 introduced. Let me show the configuration in zebra-0.8x.
1354 access-list local-only permit 127.0.0.1/32
1355 access-list local-only deny any
1357 ipv6 access-list local-only permit ::1/128
1358 ipv6 access-list local-only dny any
1361 access-class local-only
1362 ipv6 access-class local-only
1367 New IPv6 related route-map match commands are added.
1369 o match ipv6 address
1370 o match ipv6 next-hop
1372 Please change your configuration if you use IP match statement for
1378 access-list all permit any
1380 route-map set-nexthop permit 10
1381 match ip address all
1382 set ipv6 next-hop global 3ffe:506::1
1383 set ipv6 next-hop local fe80::cbb5:591a
1389 ipv6 access-list all permit any
1391 route-map set-nexthop permit 10
1392 match ipv6 address all
1393 set ipv6 next-hop global 3ffe:506::1
1394 set ipv6 next-hop local fe80::cbb5:591a
1399 Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
1400 when the connection fail. Those daemons try to connect zebra every 10
1401 seconds first three trial, then the interval changed to 60 seconds.
1402 After all, if ten connections are fail, protocol daemon give up the
1403 connection to the zebra daemon.
1405 * SNMP support (is not yet finished)
1407 Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
1408 agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
1409 and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
1410 compiled with ucd-snmp-3.6.2.
1412 After applying the patch to ucd-snmp-4.0.1, please configure it with
1415 % configure --with-mib-modules=smux
1417 After compile & install ucd-snmp-4.0.1, you will need to configure
1418 smuxpeer. I'm now using below configuration.
1420 /usr/local/share/snmp/snmpd.conf
1421 ================================
1422 smuxpeer 1.3.6.1.6.3.1 test
1424 Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard
1425 coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP.
1427 * HUP signal treatment
1429 From zebra-0.80, ripd will reload it's configuration file when ripd
1430 receives HUP signal. Other daemon such as bgpd, ospfd will support
1431 HUP signal treatment soon.
1433 * Changes in zebra-0.79
