3 * Changes in zebra-0.93
7 ** Configuration is changed to new format.
11 ** Crush bugs which reported on Zebra ML is fixed.
13 ** Opaque LSA and TE LSA support is added by KDD R&D Laboratories,

37 * Changes in zebra-0.92
39 ** Overall security is improved. Default umask is 0077.
43 ** If output interface is in simple password authentication mode,
44 substruct one from rtemax.
48 ** IPv4 multicast and IPv6 unicast configuration is changed to so
49 called new config. All of AFI and SAFI specific configuration is
50 moved to "address-family" node. When you have many IPv6 only
51 configuration, you will see many "no neighbor X:X::X:X activate" line
52 in your configuration to disable IPv4 unicast NLRI exchange. In that
53 case please use "no bgp default ipv4-unicast" command to suppress the
54 output. Until zebra-0.93, old config is still left for compatibility.

138 ** Unknown transitive attribute is passed with partial flag bit on.
142 ** Fix bug of LSA MaxAge flood.
144 ** Fix bug of NSSA codes.
146 * Changes in zebra-0.90
148 ** From this beta release, --enable-unixdomain and --enable-newrib
149 becomes default. So both options are removed from configure.in. To
150 revert old behavior please specify below option.
152 --enable-tcp-zebra # TCP/IP socket is used for protocol daemon and zebra.
153 --enable-oldrib # Turn on old RIB implementation.
155 Old RIB implementation will be removed in zebra-0.91.
157 ** From this beta release --enable-multipath is supported. This
158 option is only effective on GNU/Linux kernel with
159 CONFIG_IP_ADVANCED_ROUTER and CONFIG_IP_ROUTE_MULTIPATH is set.
161 --enable-multipath=ARG # ARG must be digit. When ARG is 0 unlimit multipath number.
163 ** From this release we do not include guile files.
167 ** newlist.[ch] is merged with linklist.[ch].
169 ** Now Zebra works on MacOS X public beta.
171 ** Access-list can have remark. "access-list WORD remark LINE" define
172 remark for specified access-list.
174 ** Key of key-chain is sorted by it's idetifier value.
176 ** prefix-list rule is slightly changed. The rule of "len <= ge-value
177 <= le-value" is changed to "len < ge-value <= le-value".
179 ** According to above prefix-list rule change, add automatic
180 conversion function of an old rule. ex.) 10.0.0.0/8 ge 8 -> 10.0.0.0/8
183 ** SMUX can handle SNMP trap.
185 ** In our event library, event thread is executed before any other
186 thread like timer, read and write event.
188 ** Robust method for writing configuration file and recover from
189 backing up config file.
191 ** Display "end" at the end of configuration.
193 ** Fix memory leak in vtysh_read().
195 ** Fix memroy leak about access-list and prefix-list name.
199 ** UNIX domain socket server of zebra protocol is added.
201 ** Fix PointoPoint interface network bug. The destination network
202 should be installed into routing table instead of local network.
204 ** Metric value is reflected to kernel routing table.
206 ** "show ip route" display uptime of RIP,OSPF,BGP routes.
208 ** New RIB implementation is added.
210 Now we have enhanced RIB (routing information base) implementation in
211 zebra. New RIB has many new features and fixed some bugs which exist
214 *** Static route with distance value
216 Static route can be specified with administrative distance. The
217 distance value 255 means it is not installed into the kernel.
218 Default value of distance for static route is 1.
220 ip route A.B.C.D/M A.B.C.D <1-255>
221 ip route A.B.C.D/M IFNAME <1-255>
223 If the least distance value's route's nexthop are unreachable,
224 select the least distance value route which has reachable nexthop is
227 ip route 0.0.0.0/0 10.0.0.1
228 ip route 0.0.0.0/0 11.0.0.1 2
230 In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
231 reachable. The route with nexthop 11.0.0.1 will be installed into
235 S>* 0.0.0.0/0 [2/0] via 11.0.0.1
236 S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
238 If the nexthop is unreachable "inactive" is displayed. You can
239 specify any string to IFNAME. There is no need of the interface is
240 there when you configure the route.
242 ip route 1.1.1.1/32 ppp0
244 When ppp0 comes up, the route is installed properly.
246 *** Multiple nexthop routes for one prefix
248 Multiple nexthop routes can be specified for one prefix. Even the
249 kernel support only one nexthop for one prefix user can configure
252 When you configure routes like below, prefix 10.0.0.1 has three
255 ip route 10.0.0.1/32 10.0.0.2
256 ip route 10.0.0.1/32 10.0.0.3
257 ip route 10.0.0.1/32 eth0
259 If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
260 is reachable, then the last route is installed into the kernel.
263 S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
264 via 10.0.0.3 inactive
265 * is directly connected, eth0
267 '*' means this nexthop is installed into the kernel.
269 *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
271 When the kernel support multipath, zebra can install multipath
272 routes into the kernel. Before doing that please make it sure that
273 setting --enable-multipath=ARG to configure script. ARG must be digit
274 value. When specify 0 to ARG, there is no limitation of the number
275 of the multipath. Currently only GNU/Linux with netlink interface is
278 ip route 10.0.0.1/32 10.0.0.2
279 ip route 10.0.0.1/32 10.0.0.3
280 ip route 10.0.0.1/32 eth0
283 S>* 10.0.0.1/32 [1/0] via 10.0.0.2
285 is directly connected, eth0
287 *** Kernel message delete installed route.
289 After zebra install static or dynamic route into the kernel.
291 R>* 0.0.0.0/0 [120/3] via 10.0.0.1
293 If you delete this route outside zebra, old zebra does not reinstall
294 route again. Now the route is re-processed and properly reinstall the
295 static or dynamic route into the kernel.
297 ** GNU/Linux netlink socket handling is improved to fix race condition
298 between kernel message and user command responce.
302 ** Add show neighbor's routes command.
304 "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes"
305 "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes"
306 "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes"
307 "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes"
309 ** BGP passive peer support problem is fixed.
311 ** Redistributed IGP nexthop is passed to BGP nexthop.
313 ** On multiaccess media, if the nexthop is reachable nexthop is passed
316 ** Remove zebra-0.88 compatibility commands.
318 "match ip prefix-list WORD"
319 "match ipv6 prefix-list WORD"
321 Instead of above please use below commands.
323 "match ip address prefix-list WORD"
324 "match ipv6 address prefix-list WORD"
326 ** Fix bug of holdtimer is not reset when bgp cleared.
328 ** "show ip bgp summary" display peer establish/drop count.
330 ** Change "match ip next-hop" argument from IP address to access-list
333 ** When "bgp enforce-first-as" is enabled, check EBGP peer's update
334 has it's AS number in the first AS number in AS sequence.
336 ** New route-map command "set community-delete COMMUNITY-LIST" is
337 added. Community matched the CoMMUNITY-LIST is removed from the
340 ** BGP-MIB implementation is finished.
342 ** When BGP connection comes from unconfigured IP address, close
345 ** Do not compare router ID when the routes comes from EBGP peer.
346 When originator ID is same, take shorter cluster-list route. If
347 cluster-list is same take smaller IP address neighbor's route.
349 ** Add "bgp bestpath as-path ignore" command. When this option is
350 set, do not concider AS path length when route selection.
352 ** Add "bgp bestpath compare-routerid". When this option is set,
353 compare router ID when the routes comes from EBGP peer.
355 ** Add "bgp deterministic-med" process.
357 ** BGP flap dampening feature is added.
359 ** When IBGP nexthop is changed, it is reflected to RIB.

366 ** Change "match ip next-hop" argument from IP address to access-list
369 ** "no ip rip (send|receive)" command accept version number argument.
371 ** Memory leak related classfull network generation is fixed.
373 ** When a route is in garbage collection process (invalid with metric
374 16) and a router receives the same route with valid metric then route
375 was not installed into zebra rib, but only into ripd rib. Moreover ,
376 it will never get into zebra rib, because ripd wrongly assumes it's
381 ** Fix bug of refreshing default route.
383 ** --enable-nssa turn on undergoing NSSA feature.
385 ** Fix bug of Hello packet's option is not properly set when interface
388 ** Reduce unconditional logging.
390 ** Add nexthop to OSPF path only when it is not there.
392 ** When there is no DR on network (suppose you have only one router
393 with interface priority 0). It's router LSA does not contain the link
394 information about this network.
396 ** When you change a priority of interface from/to 0
397 ISM_NeighborChange event should be scheduled in order to elect new
398 DR/BDR on the network.
400 ** When we add some LSA into retransmit list we need to check whether
401 the present old LSA in retransmit list is not more recent than the new
404 ** In states Loading and Full the slave must resend its last Database
405 Description packet in response to duplicate Database Description
406 packets received from the master. For this reason the slave must wait
407 RouterDeadInterval seconds before freeing the last Database
408 Description packet. Reception of a Database Description packet from
409 the master after this interval will generate a SeqNumberMismatch
410 neighbor event. RFC2328 Section 10.8
412 ** Virtual link can not configured in stub area.
414 ** Clear a ls_upd_queue queue of the interface when interface goes
417 ** "no router ospf" unregister redistribution requests from zebra.

469 /usr/local/etc/Zebra.conf file then pass the confuguration to proper
470 protocol daemon. So make all protocol daemon's configuration file
471 empty then invoke all daemon. After that vtysh -b will setup saved

811 ** Compare MED only both routes comes from same neighboring AS.
813 ** "bgp always-compare-med" command is added.
815 ** Now MED value is passed to IBGP peer.
817 ** When neighbor's filter is configured with non-existent access-list,
818 as-path access-list, ip prefix-list, route-map. The behavior is
819 changed from all permit to all deny.

914 ** Add RIP peer handling. RIP peer are shown by "show ip protocols".
916 * Changes in zebra-0.84a
920 ** Fix serious bug of BGP-4+ peering under IPv6 link-local address.
921 Due to the bug BGP-4+ peering may not be established.
923 * Changes in zebra-0.84
927 ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada
928 <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address,
929 "X:X::X:X/M" for IPv6 prefix. You can use it like this.
931 DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>")
933 ** VTY configuration is locked during configuration. This is for
934 avoiding unconditional crush from two terminals modify the
935 configuration at the same time. "who" command shows which termnal
936 lock the configuration. VTY which has '*' character at the head of
937 line is locking the configuration.
939 ** Old logging functions are removed. Functions like
940 log_open,log_close,openlog are deleted. Instead of that please use
941 zlog_* functions. zvlog_* used in ospf6d are deleted also.
943 ** "terminal monitor" command is added. "no terminal monitor" is for
944 disabling. This command simply display logging information to the
947 ** dropline.[ch] files are deleted.
951 ** BGP neighbor configuration are sorted by it's IP address.
953 ** BGP peer configuration and actual peer is separated. This is
954 preparation for Route Server support.
956 ** "no neighbor PEER" command is added. You can delete neighbor
957 without specifying AS number.
959 ** "no neighbor ebgp-multihop" command is added.
961 ** "no neighbor port PORT" command is added.
963 ** To conform RFC1771, "neighbor PEER send-community" is default
964 behavior. If you want to disable sending community attribute,
965 please specify "no neighbor PEER send-community" to the peer.
967 ** "neighbor maximum-prefix NUMBER" command is added.
969 ** Multi-protocol extention NLRI is proceeded only when the peer is
970 configured proper Address Family and Subsequent Address Family. If
971 not, those NLRI are simply ignored.
973 ** Aggregate-address support is improved. Currently below commands
977 "aggregate-address summary-only"
978 "no aggregate-address"
979 "no aggregate-address summary-only"
981 "ipv6 bgp aggregate-address"
982 "ipv6 bgp aggregate-address summary-only"
983 "no ipv6 bgp aggregate-address"
984 "no ipv6 bgp aggregate-address summary-only"
986 ** redistribute route-map bug is fixed.
988 ** MBGP support becomes default. "configure" option --enable-mbgp is
991 ** New command "neighbor PEER timers connect <1-65535>" is added.
993 ** New command "neighbor PEER override-capability" is added.
995 ** New command "show ip bgp neighbor A.B.C.D advertised-route" is added.
997 ** New command "show ip bgp neighbor A.B.C.D routes" is added. To use
998 this command, you have to configure neighbor with
999 "neighbor A.B.C.D soft-reconfiguration inbound" beforehand.
1002 * Changes in zebra-0.83
1006 ** Serious bug fix about fetching global and link-local address at the
1007 same time. Due to this bug, corrupted IPv6 prefix is generated. If
1008 you uses bgpd for BGP-4+ please update to this version. The bug is
1009 introduced in zebra-0.82.
1011 ** When bgpd send Notify message, don't use thread manager. It is now
1012 send to neighbor immediately.
1014 * Changes in zebra-0.82
1016 ** Solaris 2.6 support is added by Michael Handler
1017 <handler@sub-rosa.com>.
1019 ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>.
1020 Please specify --enable-mbgp to configure script. This option will be
1021 removed in the future and MBGP support will be default.
1025 ** When interface goes down, withdraw connected routes from routing
1026 table. When interface goes up, restore the routes to the routing
1029 ** `show interface' show interface's statistics on Linux and BSD with
1032 ** Now zebra can get MTU value on BSDI/OS.
1036 ** Add capability option support based upon
1037 draft-ietf-idr-bgp4-cap-neg-04.txt.
1039 ** Add `show ipv6 bgp prefix-list' command.
1041 ** Check self AS appeared in received routes.
1043 ** redistribute route-map support is added.
1045 ** BGP packet dump feature compatible with MRT.
1049 ** Fix bug of `timers basic' command's argument format.
1053 ** Calculate max RTE using interface's MTU value.
1057 ** Some correction to LSU processing.
1059 ** Add check for lsa->refresh_list.
1063 ** Many debug feature is added.
1065 * Changes in zebra-0.81
1067 ** SNMP support is disabled in default.--enable-snmp option is added
1068 to configure script.
1072 ** Fix FSM bug which introduced in zebra-0.80.
1074 * Changes in zebra-0.80
1078 New access-list name space `ipv6 access-list' is added. At the same
1079 time, `access-list' statemant only accepts IPv4 prefix. Please be
1080 careful if you use IPv6 filtering. You will need to change your
1081 configuration. For IPv6 filtering please use `ipv6 access-list'.
1083 As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
1087 access-list DML-net permit 203.181.89.0/24
1088 access-list DML-net permit 3ffe:506::0/32
1089 access-list DML-net deny any
1092 Above configuration is not valid for zebra-08x. Please add `ipv6'
1093 before 'access-list' when you configure IPv6 filtering.
1096 access-list DML-net permit 203.181.89.0/24
1097 access-list DML-net deny any
1099 ipv6 access-list DML-net permit 3ffe:506::0/32
1100 ipv6 access-list DML-net deny any
1105 And also new prefix-list name space `ipv6 prefix-list' is added. It
1106 is the same as the change of `access-list'. `ip prefix-list' now only
1107 accept IPv4 prefix. It was source of confusion that `ip prefix-list'
1108 can be used both IPv4 and IPv6 filtering. Now name space is separated
1109 to clear the meaning of the filter.
1111 If you use `ip prefix-list' for IPv6 filtering, please change the
1115 ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1116 ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1117 ip prefix-list 6bone-filter seq 12 deny 3ffe::/16
1118 ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1119 ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1120 ip prefix-list 6bone-filter seq 30 deny any
1123 Now user can explicitly configure it as IPv6 prefix-list.
1126 ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1127 ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1128 ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16
1129 ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1130 ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1131 ipv6 prefix-list 6bone-filter seq 30 deny any
1136 If you want to filter only default route (0.0.0.0/0) and permit other
1137 routes, it was hard to do that. Now `ip prefix-list' can be used for
1138 RIP route filtering.
1142 `distribute-list prefix PLIST_NAME (in|out) IFNAME'
1144 is added to ripd. So you can configure on eth0 interface accept all
1145 routes other than default routes.
1149 distribute-list prefix filter-default in eth0
1151 ip prefix-list filter-default deny 0.0.0.0/0 le 0
1152 ip prefix-list filter-default permit any
1155 * RIPng configuration
1157 Same change is done for ripngd. You can use `ipv6 prefix-list' for
1162 distribute-list prefix filter-default in eth0
1164 ipv6 prefix-list filter-default deny ::/0 le 0
1165 ipv6 prefix-list filter-default permit any
1170 So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
1171 done with traditional IPv4 peering statement like blow.
1175 neighbor 3ffe:506::1 remote-as 2500
1176 neighbor 3ffe:506::1 prefix-list 6bone-filter out
1179 For separating configuration IPv4 and IPv6, and for retaining Cisco
1180 configuration compatibility, now IPv6 configuration is done by IPv6
1181 specific statement. IPv6 BGP configuration is done by statement which
1182 start from `ipv6 bgp'.
1187 ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
1188 ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
1191 At the same time some IPv6 specific commands are deleted from IPv4
1194 o redistribute ripng
1195 o redistribute ospf6
1196 o neighbor PEER version BGP_VERSION
1197 o neighbor PEER interface IFNAME
1199 Those commands are only accepted as like below.
1201 o ipv6 bgp redistribute ripng
1202 o ipv6 bgp redistribute ospf6
1203 o ipv6 bgp neighbor PEER version BGP_VERSION
1204 o ipv6 bgp neighbor PEER interface IFNAME
1206 And below new commands are added.
1208 o ipv6 bgp network IPV6_PREFIX
1209 o ipv6 bgp redistribute static
1210 o ipv6 bgp redistribute connected
1211 o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
1212 o ipv6 bgp neighbor PEER ebgp-multihop [TTL]
1213 o ipv6 bgp neighbor PEER description DESCRIPTION
1214 o ipv6 bgp neighbor PEER shutdown
1215 o ipv6 bgp neighbor PEER route-reflector-client
1216 o ipv6 bgp neighbor PEER update-source IFNAME
1217 o ipv6 bgp neighbor PEER next-hop-self
1218 o ipv6 bgp neighbor PEER timers holdtime <0-65535>
1219 o ipv6 bgp neighbor PEER timers keepalive <0-65535>
1220 o ipv6 bgp neighbor PEER send-community
1221 o ipv6 bgp neighbor PEER weight <0-65535>
1222 o ipv6 bgp neighbor PEER default-originate
1223 o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out)
1224 o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
1225 o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
1226 o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
1228 And some utility commands are introduced.
1230 o clear ipv6 bgp [PEER]
1231 o show ipv6 bgp neighbors [PEER]
1232 o show ipv6 bgp summary
1234 I hope these changes are easy to understand for current Zebra users...
1236 * To restrict connection to VTY interface.
1238 It used to be both IPv4 and IPv6 filter can be specified with one
1239 access-list. Then the access-list can be appried to VTY interface
1240 with `access-class' stetement in `line vty' node. Below is example in
1244 access-list local-only permit 127.0.0.1/32
1245 access-list local-only permit ::1/128
1246 access-list local-only deny any
1249 access-class local-only
1252 Now IPv4 and IPv6 filter have each name space. It is not possible to
1253 specify IPv4 and IPv6 filter with one access-list. For setting IPv6
1254 access-list in `line vty', `ipv6 access-class' statement is
1255 introduced. Let me show the configuration in zebra-0.8x.
1258 access-list local-only permit 127.0.0.1/32
1259 access-list local-only deny any
1261 ipv6 access-list local-only permit ::1/128
1262 ipv6 access-list local-only dny any
1265 access-class local-only
1266 ipv6 access-class local-only
1271 New IPv6 related route-map match commands are added.
1273 o match ipv6 address
1274 o match ipv6 next-hop
1276 Please change your configuration if you use IP match statement for
1282 access-list all permit any
1284 route-map set-nexthop permit 10
1285 match ip address all
1286 set ipv6 next-hop global 3ffe:506::1
1287 set ipv6 next-hop local fe80::cbb5:591a
1293 ipv6 access-list all permit any
1295 route-map set-nexthop permit 10
1296 match ipv6 address all
1297 set ipv6 next-hop global 3ffe:506::1
1298 set ipv6 next-hop local fe80::cbb5:591a
1303 Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
1304 when the connection fail. Those daemons try to connect zebra every 10
1305 seconds first three trial, then the interval changed to 60 seconds.
1306 After all, if ten connections are fail, protocol daemon give up the
1307 connection to the zebra daemon.
1309 * SNMP support (is not yet finished)
1311 Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
1312 agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
1313 and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
1314 compiled with ucd-snmp-3.6.2.
1316 After applying the patch to ucd-snmp-4.0.1, please configure it with
1319 % configure --with-mib-modules=smux
1321 After compile & install ucd-snmp-4.0.1, you will need to configure
1322 smuxpeer. I'm now using below configuration.
1324 /usr/local/share/snmp/snmpd.conf
1325 ================================
1326 smuxpeer 1.3.6.1.6.3.1 test
1328 Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard
1329 coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP.
1331 * HUP signal treatment
1333 From zebra-0.80, ripd will reload it's configuration file when ripd
1334 receives HUP signal. Other daemon such as bgpd, ospfd will support
1335 HUP signal treatment soon.
1337 * Changes in zebra-0.79

1550 ** Now `terminal length 0' means no line output control.
1552 ** `line LINES' command deleted. Instead of this please use `terminal
1555 ** `terminal length <0-512>' is each vty specific configuration so it
1556 can not be configured in the configuration file. If you want to
1557 configure system wide line control, please use `service
1558 terminal-length <0-512>'. This configuration affects to the all vty
1563 ** Installation of IPv6 route bug is fixed.
1567 ** Very serious bug of bgp_stop () is fixed. When multiple route to
1568 the same destination exist, bgpd try to announce the information to
1569 stopped peer. Then add orphan write thread is added. This cause
1570 many strange behavior of bgpd.
1572 ** Router-id parsing bug is fixed.
1574 ** With BGP-4+ nexthop installation was done with global address but
1575 it should be link-local address. This bug is fixed now.
1577 ** When incoming route-map prepend AS, old AS path remained. Now bgpd
1580 ** `neighbor PEER weight <0-65535>' command added.
1584 ** Almost codes are rewritten to conform to RFC2080.
1588 ** SPF calculation timer is added. Currently it is set to 30 seconds.
1590 ** SPF calculation works now.
1592 ** OSPF routing table codes are added.

1623 ** In interface node, `ipv6 address' and `no ipv6 address' works.
1625 ** Interface's address remain after `no ip address' bug is fixed.
1627 ** Host route such as IPv4 with /32 mask and IPv6 with /128 mask
1628 didn't set RTF_GATEWAY even it has gateway. This bug if fixed now.
1632 ** `match as-path' argument is used to be specify AS PATH value itself
1633 directly (e.g. ^$). But it is changed to specify `ip as-apth
1636 ** iBGP route handle works without getting error from the kernel.
1638 ** `set aggregator as AS A.B.C.D' command is added to route-map.
1640 ** `set atomic-aggregate' command is added to bgpd's routemap.
1642 ** Announcement of atomic aggregate attribute and aggregator attribute
