3: * Changes in Quagga 0.99.21
4:
5: - [bgpd] BGP multipath support has been merged
6: - [bgpd] SAFI (Multicast topology) support has been extended to propagate
7: the topology to zebra.
8: - [bgpd] AS path limit functionality has been removed
9: - [babeld] a new routing daemon implementing the BABEL ad-hoc mesh routing
10: protocol has been merged.
11: - [isisd] a major overhaul has been picked up. Please note that isisd is
12: STILL NOT SUITABLE FOR PRODUCTION USE.
13: - [*] a lot of bugs have been fixed, please refer to the git log
14:
15: * Changes in Quagga 0.99.10
16:
17: - [bgpd] 4-byte AS support added
18: - [bgpd] MRT format changes to version 2. Those relying on
19: bgpd MRT table dumps may need to update their tools.
20: - [bgpd] Added new route-map set statement: "as-path exclude"
21: - Zebra RIB updates queue has evolved into a multi-level
22: structure to address RIB consistency issues.
23:
24: * Changes in Quagga 0.99.2
25:
26: - [bgpd] Work queues added to bgpd to split up update processing,
27: particularly beneficial when a peer session goes down. AS_PATH
28: parsing rewritten to be clearer, more robust and ready for 4-byte.
29:
30: - [ripd] Simple authentication is no longer the default authentication
31: mode for ripd. The default is now no-authentication. Any setups which
32: used simple authentication will probably need to update their
33: configuration manually.
34:
35: - [ospfd] 1s dead-interval with sub-second Hellos feature added.
36: SPF timers now specified in milliseconds, and with adaptive
37: hold-time support. RFC3137 Stub-router support added. Default ABR
38: type is now 'cisco'.
39:
40: - Solaris least privileges support added.
41:
42: * Changes in Quagga 0.99.1
43:
44: - Zserv is now buffered via threads and non-blocking in most cases for both
45: clients and zebra, which should improve responsiveness of daemons when
46: they must send many messages to zebra.
47:
48: - 'show thread cpu' now displays both cpu+system and wall-clock time,
49: where getrusage() is available.
50:
51: - Background threads added and workqueue API added, with a
52: 'show work-queues' command. Thread scheduling improved slightly.
53:
54: - Zebra now has a work-queue for RIB processing. See 'show work-queues' in
55: the zebra daemon vty.
56:
57: - Support for interface renaming on Linux netlink systems.
58:
59: - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip
60: route-source" command.
61:
62: - Automatic logging of backtraces should daemons crash to assist in
63: diagnosis. See the documentation for more information on configuring
64: logging correctly, and set --enable-gcc-rdynamic if compiling with gcc.
65:
66: * Changes in Quagga 0.98.0
67:
68: - Logging facilities upgraded. One can now specify a severity level
69: for each logging destination. And a new "show logging" command gives
70: thorough information on the current logging system configuration.
71:
72: - Watchquagga daemon added. This is not well tested yet. Please try
73: monitor mode first before enabling restart features. It is important
74: to make sure that the various timers are configured with appropriate
75: values for your site.
76:
77: - BGP route-server support added. See the texinfo documentation.
78:
79: - OSPF API initialisation is disabled by default even if compiled in. You
80: can enable it with -a/--apiserver command line switch.
81:
82: - "write-config integrated" vtysh command replaced with "service
83: integrated-vtysh-config" command.
84:
85: - Router id is now handled by zebra daemon and all daemons receive changes
86: from it. Router id can be overriden in daemons' configurations of course.
87: To fix common router id in zebra daemon you can either install non-127
88: address on loopback or use "router-id x.x.x.x" command.
89:
90: - "secondary" keyword is removed from ip address configuration. All
91: supported OS'es have their own vision what's secondary address and
92: how to handle it.
93:
94: - Zebra no longer enables forwarding by default. If you rely on zebra to
95: enable forwarding make sure to add '<ip|ip6> forwarding' statements
96: to your zebra configuration file.
97:
98: - All libraries are built and used shared, on platforms where libtool
99: supports shared libraries.
100:
101: - Router advertisement syntax is changed. In usual cases (if you didn't do
102: any fancy stuff) it's enough to change lines in configuration from:
103: "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link"
104: to:
105: "ipv6 nd prefix X:X:X:X::/X"
106:
107: All router advertisement options are documented in texi documentation.
108:
109: - --enable-nssa configure switch is removed. NSSA support is stable enough.
110:
111: - Daemons don't look at current directory for config file any more.
112:
113: * Changes in Quagga 0.96.5
114:
115: - include files are installed in $(prefix)/include/quagga. Programs
116: building against these includes should -I$(prefix)/include and e.g.
117: #include <quagga/routemap.h>
118:
119: - New option --enable-exampledir puts example files in a separate
120: directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules
121: compliance.
122:
123: - New configure options --enable-configfile-mask and
124: --enable-logfile-mask to set umask values for config and log
125: values. Masks default to 0600, matching previous behavior.
126:
127: - Import current CVS isisd from SourceForge, then merge it with
128: the Quagga's Framework.
129:
130: * Changes in Quagga 0.96.4
131:
132: - Further fixes to ospfd, some relating to the PtP revert. Interface
133: lookups should be a lot more robust now.
134:
135: - Fix for a remote triggerable crash in vty layer.
136:
137: - Improvements to ripd, and addition of split horizon support.
138:
139: - Improved bgpd table support, now dumps at time of day intervals rather
140: than time from startup intervals. Much improved support for IPv6 table
141: dumps. show commands for views improved.
142:
143: * Changes in Quagga 0.96.3
144:
145: - revert the 'generic PtP' patch. Means Quagga will no longer work with
146: FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs
147: which the PtP patch introduced.
148:
149: * Changes in Quagga 0.96.2
150:
151: - Fix crash in ospfd
152:
153: * Changes in Quagga 0.96.1

210:
211: * Changes in bgpd
212:
213: ** IPv4 multicast and IPv6 unicast configuration is changed to so
214: called new config. All of AFI and SAFI specific configuration is
215: moved to "address-family" node. When you have many IPv6 only
216: configuration, you will see many "no neighbor X:X::X:X activate" line
217: in your configuration to disable IPv4 unicast NLRI exchange. In that
218: case please use "no bgp default ipv4-unicast" command to suppress the
219: output. Until zebra-0.93, old config is still left for compatibility.

377: in old RIB code.
378:
379: *** Static route with distance value
380:
381: Static route can be specified with administrative distance. The
382: distance value 255 means it is not installed into the kernel.
383: Default value of distance for static route is 1.
384:
385: ip route A.B.C.D/M A.B.C.D <1-255>
386: ip route A.B.C.D/M IFNAME <1-255>
387:
388: If the least distance value's route's nexthop are unreachable,
389: select the least distance value route which has reachable nexthop is
390: selected.
391:
392: ip route 0.0.0.0/0 10.0.0.1
393: ip route 0.0.0.0/0 11.0.0.1 2
394:
395: In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
396: reachable. The route with nexthop 11.0.0.1 will be installed into
397: forwarding table.
398:
399: zebra> show ip route
400: S>* 0.0.0.0/0 [2/0] via 11.0.0.1
401: S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
402:
403: If the nexthop is unreachable "inactive" is displayed. You can
404: specify any string to IFNAME. There is no need of the interface is
405: there when you configure the route.
406:
407: ip route 1.1.1.1/32 ppp0
408:
409: When ppp0 comes up, the route is installed properly.
410:
411: *** Multiple nexthop routes for one prefix
412:
413: Multiple nexthop routes can be specified for one prefix. Even the
414: kernel support only one nexthop for one prefix user can configure
415: multiple nexthop.
416:
417: When you configure routes like below, prefix 10.0.0.1 has three
418: nexthop.
419:
420: ip route 10.0.0.1/32 10.0.0.2
421: ip route 10.0.0.1/32 10.0.0.3
422: ip route 10.0.0.1/32 eth0
423:
424: If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
425: is reachable, then the last route is installed into the kernel.
426:
427: zebra> show ip route
428: S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
429: via 10.0.0.3 inactive
430: * is directly connected, eth0
431:
432: '*' means this nexthop is installed into the kernel.
433:
434: *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
435:
436: When the kernel support multipath, zebra can install multipath
437: routes into the kernel. Before doing that please make it sure that
438: setting --enable-multipath=ARG to configure script. ARG must be digit
439: value. When specify 0 to ARG, there is no limitation of the number
440: of the multipath. Currently only GNU/Linux with netlink interface is
441: supported.
442:
443: ip route 10.0.0.1/32 10.0.0.2
444: ip route 10.0.0.1/32 10.0.0.3
445: ip route 10.0.0.1/32 eth0
446:
447: zebra> show ip route
448: S>* 10.0.0.1/32 [1/0] via 10.0.0.2
449: * via 10.0.0.3
450: is directly connected, eth0
451:
452: *** Kernel message delete installed route.
453:
454: After zebra install static or dynamic route into the kernel.
455:
456: R>* 0.0.0.0/0 [120/3] via 10.0.0.1
457:
458: If you delete this route outside zebra, old zebra does not reinstall
459: route again. Now the route is re-processed and properly reinstall the
460: static or dynamic route into the kernel.
461:
462: ** GNU/Linux netlink socket handling is improved to fix race condition
463: between kernel message and user command responce.
464:
465: * Changes in bgpd
466:
467: ** Add show neighbor's routes command.
468:

470: "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes"
471: "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes"
472: "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes"
473:
474: ** BGP passive peer support problem is fixed.
475:
476: ** Redistributed IGP nexthop is passed to BGP nexthop.
477:
478: ** On multiaccess media, if the nexthop is reachable nexthop is passed
479: as it is.
480:
481: ** Remove zebra-0.88 compatibility commands.
482:
483: "match ip prefix-list WORD"
484: "match ipv6 prefix-list WORD"
485:
486: Instead of above please use below commands.
487:
488: "match ip address prefix-list WORD"
489: "match ipv6 address prefix-list WORD"
490:
491: ** Fix bug of holdtimer is not reset when bgp cleared.
492:
493: ** "show ip bgp summary" display peer establish/drop count.
494:
495: ** Change "match ip next-hop" argument from IP address to access-list
496: name.
497:
498: ** When "bgp enforce-first-as" is enabled, check EBGP peer's update
499: has it's AS number in the first AS number in AS sequence.
500:
501: ** New route-map command "set community-delete COMMUNITY-LIST" is
502: added. Community matched the CoMMUNITY-LIST is removed from the
503: community.
504:
505: ** BGP-MIB implementation is finished.
506:
507: ** When BGP connection comes from unconfigured IP address, close
508: socket immediately.
509:
510: ** Do not compare router ID when the routes comes from EBGP peer.
511: When originator ID is same, take shorter cluster-list route. If
512: cluster-list is same take smaller IP address neighbor's route.
513:
514: ** Add "bgp bestpath as-path ignore" command. When this option is
515: set, do not concider AS path length when route selection.
516:
517: ** Add "bgp bestpath compare-routerid". When this option is set,
518: compare router ID when the routes comes from EBGP peer.
519:
520: ** Add "bgp deterministic-med" process.
521:
522: ** BGP flap dampening feature is added.
523:

525:
526: ** Change "neighbor route-refresh" command to "neighbor capability
527: route-refresh".

531: ** Change "match ip next-hop" argument from IP address to access-list
532: name.
533:
534: ** "no ip rip (send|receive)" command accept version number argument.
535:
536: ** Memory leak related classfull network generation is fixed.
537:
538: ** When a route is in garbage collection process (invalid with metric
539: 16) and a router receives the same route with valid metric then route

1106: zlog_* functions. zvlog_* used in ospf6d are deleted also.
1107:
1108: ** "terminal monitor" command is added. "no terminal monitor" is for
1109: disabling. This command simply display logging information to the
1110: VTY.
1111:
1112: ** dropline.[ch] files are deleted.
1113:
1114: * Changes in bgpd
1115:
1116: ** BGP neighbor configuration are sorted by it's IP address.
1117:
1118: ** BGP peer configuration and actual peer is separated. This is
1119: preparation for Route Server support.
1120:
1121: ** "no neighbor PEER" command is added. You can delete neighbor
1122: without specifying AS number.
1123:
1124: ** "no neighbor ebgp-multihop" command is added.
1125:
1126: ** "no neighbor port PORT" command is added.
1127:
1128: ** To conform RFC1771, "neighbor PEER send-community" is default
1129: behavior. If you want to disable sending community attribute,
1130: please specify "no neighbor PEER send-community" to the peer.
1131:
1132: ** "neighbor maximum-prefix NUMBER" command is added.
1133:
1134: ** Multi-protocol extention NLRI is proceeded only when the peer is
1135: configured proper Address Family and Subsequent Address Family. If
1136: not, those NLRI are simply ignored.
1137:
1138: ** Aggregate-address support is improved. Currently below commands
1139: works.
1140:
1141: "aggregate-address"
1142: "aggregate-address summary-only"
1143: "no aggregate-address"
1144: "no aggregate-address summary-only"

1150:
1151: ** redistribute route-map bug is fixed.
1152:
1153: ** MBGP support becomes default. "configure" option --enable-mbgp is
1154: removed.
1155:

1165:
1166:
1167: * Changes in zebra-0.83
1168:
1169: * bgpd
1170:
1171: ** Serious bug fix about fetching global and link-local address at the
1172: same time. Due to this bug, corrupted IPv6 prefix is generated. If
1173: you uses bgpd for BGP-4+ please update to this version. The bug is
1174: introduced in zebra-0.82.
1175:
1176: ** When bgpd send Notify message, don't use thread manager. It is now
1177: send to neighbor immediately.
1178:
1179: * Changes in zebra-0.82
1180:
1181: ** Solaris 2.6 support is added by Michael Handler
1182: <handler@sub-rosa.com>.
1183:
1184: ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>.
1185: Please specify --enable-mbgp to configure script. This option will be
1186: removed in the future and MBGP support will be default.
1187:
1188: * Changes in zebra
1189:
1190: ** When interface goes down, withdraw connected routes from routing
1191: table. When interface goes up, restore the routes to the routing
1192: table.
1193:
1194: ** `show interface' show interface's statistics on Linux and BSD with
1195: routing socket.
1196:

1209:
1210: ** BGP packet dump feature compatible with MRT.
1211:
1212: * Changes in ripd
1213:
1214: ** Fix bug of `timers basic' command's argument format.
1215:
1216: * Changes in ripngd
1217:

1223:
1224: ** Add check for lsa->refresh_list.
1225:
1226: * Changes in ospf6d
1227:
1228: ** Many debug feature is added.
1229:
1230: * Changes in zebra-0.81
1231:
1232: ** SNMP support is disabled in default.--enable-snmp option is added
1233: to configure script.
1234:
1235: * Changes in bgpd
1236:
1237: ** Fix FSM bug which introduced in zebra-0.80.
1238:
1239: * Changes in zebra-0.80
1240:
1241: * access-list
1242:
1243: New access-list name space `ipv6 access-list' is added. At the same
1244: time, `access-list' statemant only accepts IPv4 prefix. Please be
1245: careful if you use IPv6 filtering. You will need to change your
1246: configuration. For IPv6 filtering please use `ipv6 access-list'.
1247:
1248: As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
1249: filtering.
1250:
1251: ! zebra-0.7x
1252: access-list DML-net permit 203.181.89.0/24
1253: access-list DML-net permit 3ffe:506::0/32
1254: access-list DML-net deny any
1255: !
1256:
1257: Above configuration is not valid for zebra-08x. Please add `ipv6'
1258: before 'access-list' when you configure IPv6 filtering.
1259:
1260: ! zebra-0.8x
1261: access-list DML-net permit 203.181.89.0/24
1262: access-list DML-net deny any
1263: !
1264: ipv6 access-list DML-net permit 3ffe:506::0/32
1265: ipv6 access-list DML-net deny any
1266: !
1267:
1268: * prefix-list
1269:
1270: And also new prefix-list name space `ipv6 prefix-list' is added. It
1271: is the same as the change of `access-list'. `ip prefix-list' now only
1272: accept IPv4 prefix. It was source of confusion that `ip prefix-list'
1273: can be used both IPv4 and IPv6 filtering. Now name space is separated
1274: to clear the meaning of the filter.
1275:
1276: If you use `ip prefix-list' for IPv6 filtering, please change the
1277: stetement.
1278:
1279: ! zebra-0.7x
1280: ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1281: ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1282: ip prefix-list 6bone-filter seq 12 deny 3ffe::/16
1283: ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1284: ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1285: ip prefix-list 6bone-filter seq 30 deny any
1286: !
1287:
1288: Now user can explicitly configure it as IPv6 prefix-list.
1289:
1290: ! zebra-0.8x
1291: ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1292: ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28

1294: ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1295: ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1296: ipv6 prefix-list 6bone-filter seq 30 deny any
1297: !
1298:
1299: * RIP configuration
1300:
1301: If you want to filter only default route (0.0.0.0/0) and permit other
1302: routes, it was hard to do that. Now `ip prefix-list' can be used for
1303: RIP route filtering.
1304:
1305: New statement:
1306:
1307: `distribute-list prefix PLIST_NAME (in|out) IFNAME'
1308:
1309: is added to ripd. So you can configure on eth0 interface accept all
1310: routes other than default routes.
1311:
1312: !
1313: router rip
1314: distribute-list prefix filter-default in eth0
1315: !
1316: ip prefix-list filter-default deny 0.0.0.0/0 le 0
1317: ip prefix-list filter-default permit any
1318: !
1319:
1320: * RIPng configuration
1321:
1322: Same change is done for ripngd. You can use `ipv6 prefix-list' for
1323: filtering.
1324:
1325: !
1326: router ripng
1327: distribute-list prefix filter-default in eth0
1328: !
1329: ipv6 prefix-list filter-default deny ::/0 le 0
1330: ipv6 prefix-list filter-default permit any
1331: !
1332:
1333: * BGP configuration
1334:
1335: So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
1336: done with traditional IPv4 peering statement like blow.
1337:
1338: !
1339: router bgp 7675
1340: neighbor 3ffe:506::1 remote-as 2500
1341: neighbor 3ffe:506::1 prefix-list 6bone-filter out
1342: !
1343:
1344: For separating configuration IPv4 and IPv6, and for retaining Cisco
1345: configuration compatibility, now IPv6 configuration is done by IPv6
1346: specific statement. IPv6 BGP configuration is done by statement which
1347: start from `ipv6 bgp'.
1348:
1349: !
1350: router bgp 7675
1351: !
1352: ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
1353: ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
1354: !
1355:
1356: At the same time some IPv6 specific commands are deleted from IPv4
1357: configuration.
1358:
1359: o redistribute ripng
1360: o redistribute ospf6
1361: o neighbor PEER version BGP_VERSION
1362: o neighbor PEER interface IFNAME
1363:
1364: Those commands are only accepted as like below.
1365:
1366: o ipv6 bgp redistribute ripng
1367: o ipv6 bgp redistribute ospf6
1368: o ipv6 bgp neighbor PEER version BGP_VERSION
1369: o ipv6 bgp neighbor PEER interface IFNAME
1370:
1371: And below new commands are added.
1372:
1373: o ipv6 bgp network IPV6_PREFIX
1374: o ipv6 bgp redistribute static
1375: o ipv6 bgp redistribute connected
1376: o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
1377: o ipv6 bgp neighbor PEER ebgp-multihop [TTL]
1378: o ipv6 bgp neighbor PEER description DESCRIPTION
1379: o ipv6 bgp neighbor PEER shutdown
1380: o ipv6 bgp neighbor PEER route-reflector-client
1381: o ipv6 bgp neighbor PEER update-source IFNAME
1382: o ipv6 bgp neighbor PEER next-hop-self
1383: o ipv6 bgp neighbor PEER timers holdtime <0-65535>
1384: o ipv6 bgp neighbor PEER timers keepalive <0-65535>
1385: o ipv6 bgp neighbor PEER send-community
1386: o ipv6 bgp neighbor PEER weight <0-65535>
1387: o ipv6 bgp neighbor PEER default-originate
1388: o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out)
1389: o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
1390: o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
1391: o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
1392:
1393: And some utility commands are introduced.
1394:
1395: o clear ipv6 bgp [PEER]
1396: o show ipv6 bgp neighbors [PEER]
1397: o show ipv6 bgp summary
1398:
1399: I hope these changes are easy to understand for current Zebra users...
1400:
1401: * To restrict connection to VTY interface.
1402:
1403: It used to be both IPv4 and IPv6 filter can be specified with one
1404: access-list. Then the access-list can be appried to VTY interface
1405: with `access-class' stetement in `line vty' node. Below is example in
1406: zebra-0.7x.
1407:
1408: !
1409: access-list local-only permit 127.0.0.1/32
1410: access-list local-only permit ::1/128
1411: access-list local-only deny any
1412: !
1413: line vty
1414: access-class local-only
1415: !
1416:
1417: Now IPv4 and IPv6 filter have each name space. It is not possible to
1418: specify IPv4 and IPv6 filter with one access-list. For setting IPv6
1419: access-list in `line vty', `ipv6 access-class' statement is
1420: introduced. Let me show the configuration in zebra-0.8x.
1421:
1422: !
1423: access-list local-only permit 127.0.0.1/32
1424: access-list local-only deny any
1425: !
1426: ipv6 access-list local-only permit ::1/128
1427: ipv6 access-list local-only dny any
1428: !
1429: line vty
1430: access-class local-only
1431: ipv6 access-class local-only
1432: !
1433:
1434: * route-map
1435:
1436: New IPv6 related route-map match commands are added.
1437:
1438: o match ipv6 address
1439: o match ipv6 next-hop
1440:
1441: Please change your configuration if you use IP match statement for
1442: IPv6 route.
1443:
1444: zebra-0.7x config
1445: =================
1446: !
1447: access-list all permit any
1448: !

1464: !
1465:
1466: * zebra connection
1467:
1468: Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
1469: when the connection fail. Those daemons try to connect zebra every 10
1470: seconds first three trial, then the interval changed to 60 seconds.
1471: After all, if ten connections are fail, protocol daemon give up the
1472: connection to the zebra daemon.
1473:
1474: * SNMP support (is not yet finished)
1475:
1476: Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
1477: agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
1478: and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
1479: compiled with ucd-snmp-3.6.2.
1480:
1481: After applying the patch to ucd-snmp-4.0.1, please configure it with
1482: SMUX module.
1483:
1484: % configure --with-mib-modules=smux
1485:
1486: After compile & install ucd-snmp-4.0.1, you will need to configure
1487: smuxpeer. I'm now using below configuration.
1488:
1489: /usr/local/share/snmp/snmpd.conf
1490: ================================
1491: smuxpeer 1.3.6.1.6.3.1 test
1492:
1493: Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard
1494: coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP.
1495:
1496: * HUP signal treatment
1497:
1498: From zebra-0.80, ripd will reload it's configuration file when ripd
1499: receives HUP signal. Other daemon such as bgpd, ospfd will support
1500: HUP signal treatment soon.
1501:
