Annotation of embedaddon/quagga/NEWS, revision 1.1.1.1
1.1 misho 1: * Changes in Quagga 0.99.10
2:
3: - [bgpd] 4-byte AS support added
4: - [bgpd] MRT format changes to version 2. Those relying on
5: bgpd MRT table dumps may need to update their tools.
6: - [bgpd] Added new route-map set statement: "as-path exclude"
7: - Zebra RIB updates queue has evolved into a multi-level
8: structure to address RIB consistency issues.
9:
10: * Changes in Quagga 0.99.2
11:
12: - [bgpd] Work queues added to bgpd to split up update processing,
13: particularly beneficial when a peer session goes down. AS_PATH
14: parsing rewritten to be clearer, more robust and ready for 4-byte.
15:
16: - [ripd] Simple authentication is no longer the default authentication
17: mode for ripd. The default is now no-authentication. Any setups which
18: used simple authentication will probably need to update their
19: configuration manually.
20:
21: - [ospfd] 1s dead-interval with sub-second Hellos feature added.
22: SPF timers now specified in milliseconds, and with adaptive
23: hold-time support. RFC3137 Stub-router support added. Default ABR
24: type is now 'cisco'.
25:
26: - Solaris least privileges support added.
27:
28: * Changes in Quagga 0.99.1
29:
30: - Zserv is now buffered via threads and non-blocking in most cases for both
31: clients and zebra, which should improve responsiveness of daemons when
32: they must send many messages to zebra.
33:
34: - 'show thread cpu' now displays both cpu+system and wall-clock time,
35: where getrusage() is available.
36:
37: - Background threads added and workqueue API added, with a
38: 'show work-queues' command. Thread scheduling improved slightly.
39:
40: - Zebra now has a work-queue for RIB processing. See 'show work-queues' in
41: the zebra daemon vty.
42:
43: - Support for interface renaming on Linux netlink systems.
44:
45: - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip
46: route-source" command.
47:
48: - Automatic logging of backtraces should daemons crash to assist in
49: diagnosis. See the documentation for more information on configuring
50: logging correctly, and set --enable-gcc-rdynamic if compiling with gcc.
51:
52: * Changes in Quagga 0.98.0
53:
54: - Logging facilities upgraded. One can now specify a severity level
55: for each logging destination. And a new "show logging" command gives
56: thorough information on the current logging system configuration.
57:
58: - Watchquagga daemon added. This is not well tested yet. Please try
59: monitor mode first before enabling restart features. It is important
60: to make sure that the various timers are configured with appropriate
61: values for your site.
62:
63: - BGP route-server support added. See the texinfo documentation.
64:
65: - OSPF API initialisation is disabled by default even if compiled in. You
66: can enable it with -a/--apiserver command line switch.
67:
68: - "write-config integrated" vtysh command replaced with "service
69: integrated-vtysh-config" command.
70:
71: - Router id is now handled by zebra daemon and all daemons receive changes
72: from it. Router id can be overriden in daemons' configurations of course.
73: To fix common router id in zebra daemon you can either install non-127
74: address on loopback or use "router-id x.x.x.x" command.
75:
76: - "secondary" keyword is removed from ip address configuration. All
77: supported OS'es have their own vision what's secondary address and
78: how to handle it.
79:
80: - Zebra no longer enables forwarding by default. If you rely on zebra to
81: enable forwarding make sure to add '<ip|ip6> forwarding' statements
82: to your zebra configuration file.
83:
84: - All libraries are built and used shared, on platforms where libtool
85: supports shared libraries.
86:
87: - Router advertisement syntax is changed. In usual cases (if you didn't do
88: any fancy stuff) it's enough to change lines in configuration from:
89: "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link"
90: to:
91: "ipv6 nd prefix X:X:X:X::/X"
92:
93: All router advertisement options are documented in texi documentation.
94:
95: - --enable-nssa configure switch is removed. NSSA support is stable enough.
96:
97: - Daemons don't look at current directory for config file any more.
98:
99: * Changes in Quagga 0.96.5
100:
101: - include files are installed in $(prefix)/include/quagga. Programs
102: building against these includes should -I$(prefix)/include and e.g.
103: #include <quagga/routemap.h>
104:
105: - New option --enable-exampledir puts example files in a separate
106: directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules
107: compliance.
108:
109: - New configure options --enable-configfile-mask and
110: --enable-logfile-mask to set umask values for config and log
111: values. Masks default to 0600, matching previous behavior.
112:
113: - Import current CVS isisd from SourceForge, then merge it with
114: the Quagga's Framework.
115:
116: * Changes in Quagga 0.96.4
117:
118: - Further fixes to ospfd, some relating to the PtP revert. Interface
119: lookups should be a lot more robust now.
120:
121: - Fix for a remote triggerable crash in vty layer.
122:
123: - Improvements to ripd, and addition of split horizon support.
124:
125: - Improved bgpd table support, now dumps at time of day intervals rather
126: than time from startup intervals. Much improved support for IPv6 table
127: dumps. show commands for views improved.
128:
129: * Changes in Quagga 0.96.3
130:
131: - revert the 'generic PtP' patch. Means Quagga will no longer work with
132: FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs
133: which the PtP patch introduced.
134:
135: * Changes in Quagga 0.96.2
136:
137: - Fix crash in ospfd
138:
139: * Changes in Quagga 0.96.1
140:
141: - Iron out problem with the privileges definitions
142:
143: * Changes in Quagga 0.96
144:
145: - Privilege support, daemons now run with the minimal privileges needed, see
146: the documentation for details.
147:
148: - NSSA ABR support in ospfd.
149:
150: - OSPF-API support merged in.
151:
152: - 6WIND patch merged in.

202: configuration, you will see many "no neighbor X:X::X:X activate" line
203: in your configuration to disable IPv4 unicast NLRI exchange. In that
204: case please use "no bgp default ipv4-unicast" command to suppress the
205: output. Until zebra-0.93, old config is still left for compatibility.

362: zebra. New RIB has many new features and fixed some bugs which exist
363: in old RIB code.
364:
365: *** Static route with distance value
366:
367: Static route can be specified with administrative distance. The
368: distance value 255 means it is not installed into the kernel.
369: Default value of distance for static route is 1.
370:
371: ip route A.B.C.D/M A.B.C.D <1-255>
372: ip route A.B.C.D/M IFNAME <1-255>
373:
374: If the least distance value's route's nexthop are unreachable,
375: select the least distance value route which has reachable nexthop is
376: selected.
377:
378: ip route 0.0.0.0/0 10.0.0.1
379: ip route 0.0.0.0/0 11.0.0.1 2
380:
381: In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
382: reachable. The route with nexthop 11.0.0.1 will be installed into
383: forwarding table.
384:
385: zebra> show ip route
386: S>* 0.0.0.0/0 [2/0] via 11.0.0.1
387: S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
388:
389: If the nexthop is unreachable "inactive" is displayed. You can
390: specify any string to IFNAME. There is no need of the interface is
391: there when you configure the route.
392:
393: ip route 1.1.1.1/32 ppp0
394:
395: When ppp0 comes up, the route is installed properly.
396:
397: *** Multiple nexthop routes for one prefix
398:
399: Multiple nexthop routes can be specified for one prefix. Even the
400: kernel support only one nexthop for one prefix user can configure
401: multiple nexthop.
402:
403: When you configure routes like below, prefix 10.0.0.1 has three
404: nexthop.
405:
406: ip route 10.0.0.1/32 10.0.0.2
407: ip route 10.0.0.1/32 10.0.0.3
408: ip route 10.0.0.1/32 eth0
409:
410: If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
411: is reachable, then the last route is installed into the kernel.
412:
413: zebra> show ip route
414: S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
415: via 10.0.0.3 inactive
416: * is directly connected, eth0
417:
418: '*' means this nexthop is installed into the kernel.
419:
420: *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
421:
422: When the kernel support multipath, zebra can install multipath
423: routes into the kernel. Before doing that please make it sure that
424: setting --enable-multipath=ARG to configure script. ARG must be digit
425: value. When specify 0 to ARG, there is no limitation of the number
426: of the multipath. Currently only GNU/Linux with netlink interface is
427: supported.
428:
429: ip route 10.0.0.1/32 10.0.0.2
430: ip route 10.0.0.1/32 10.0.0.3
431: ip route 10.0.0.1/32 eth0
432:
433: zebra> show ip route
434: S>* 10.0.0.1/32 [1/0] via 10.0.0.2
435: * via 10.0.0.3
436: is directly connected, eth0
437:
438: *** Kernel message delete installed route.
439:
440: After zebra install static or dynamic route into the kernel.
441:
442: R>* 0.0.0.0/0 [120/3] via 10.0.0.1
443:
444: If you delete this route outside zebra, old zebra does not reinstall
445: route again. Now the route is re-processed and properly reinstall the
446: static or dynamic route into the kernel.
447:
448: ** GNU/Linux netlink socket handling is improved to fix race condition
449: between kernel message and user command responce.
450:
451: * Changes in bgpd
452:
453: ** Add show neighbor's routes command.
454:
455: "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes"
456: "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes"
457: "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes"
458: "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes"
459:
460: ** BGP passive peer support problem is fixed.
461:
462: ** Redistributed IGP nexthop is passed to BGP nexthop.
463:
464: ** On multiaccess media, if the nexthop is reachable nexthop is passed
465: as it is.
466:
467: ** Remove zebra-0.88 compatibility commands.
468:
469: "match ip prefix-list WORD"
470: "match ipv6 prefix-list WORD"
471:
472: Instead of above please use below commands.
473:
474: "match ip address prefix-list WORD"
475: "match ipv6 address prefix-list WORD"
476:
477: ** Fix bug of holdtimer is not reset when bgp cleared.
478:
479: ** "show ip bgp summary" display peer establish/drop count.

485: has it's AS number in the first AS number in AS sequence.
486:
487: ** New route-map command "set community-delete COMMUNITY-LIST" is
488: added. Community matched the CoMMUNITY-LIST is removed from the
489: community.
490:
491: ** BGP-MIB implementation is finished.
492:
493: ** When BGP connection comes from unconfigured IP address, close
494: socket immediately.
495:
496: ** Do not compare router ID when the routes comes from EBGP peer.
497: When originator ID is same, take shorter cluster-list route. If
498: cluster-list is same take smaller IP address neighbor's route.
499:
500: ** Add "bgp bestpath as-path ignore" command. When this option is
501: set, do not concider AS path length when route selection.
502:
503: ** Add "bgp bestpath compare-routerid". When this option is set,
504: compare router ID when the routes comes from EBGP peer.
505:
506: ** Add "bgp deterministic-med" process.
507:
508: ** BGP flap dampening feature is added.

518: name.
519:
520: ** "no ip rip (send|receive)" command accept version number argument.
521:
522: ** Memory leak related classfull network generation is fixed.
523:
524: ** When a route is in garbage collection process (invalid with metric
525: 16) and a router receives the same route with valid metric then route
526: was not installed into zebra rib, but only into ripd rib. Moreover ,
527: it will never get into zebra rib, because ripd wrongly assumes it's
528: already there.
529:
530: * Change in ospfd

1110: ** "no neighbor ebgp-multihop" command is added.
1111:
1112: ** "no neighbor port PORT" command is added.
1113:
1114: ** To conform RFC1771, "neighbor PEER send-community" is default
1115: behavior. If you want to disable sending community attribute,
1116: please specify "no neighbor PEER send-community" to the peer.
1117:
1118: ** "neighbor maximum-prefix NUMBER" command is added.
1119:
1120: ** Multi-protocol extention NLRI is proceeded only when the peer is
1121: configured proper Address Family and Subsequent Address Family. If
1122: not, those NLRI are simply ignored.
1123:
1124: ** Aggregate-address support is improved. Currently below commands
1125: works.
1126:
1127: "aggregate-address"
1128: "aggregate-address summary-only"
1129: "no aggregate-address"
1130: "no aggregate-address summary-only"

1151:
1152:
1153: * Changes in zebra-0.83
1154:
1155: * bgpd
1156:
1157: ** Serious bug fix about fetching global and link-local address at the
1158: same time. Due to this bug, corrupted IPv6 prefix is generated. If
1159: you uses bgpd for BGP-4+ please update to this version. The bug is
1160: introduced in zebra-0.82.
1161:
1162: ** When bgpd send Notify message, don't use thread manager. It is now
1163: send to neighbor immediately.
1164:
1165: * Changes in zebra-0.82
1166:
1167: ** Solaris 2.6 support is added by Michael Handler
1168: <handler@sub-rosa.com>.
1169:
1170: ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>.
1171: Please specify --enable-mbgp to configure script. This option will be
1172: removed in the future and MBGP support will be default.
1173:
1174: * Changes in zebra
1175:
1176: ** When interface goes down, withdraw connected routes from routing
1177: table. When interface goes up, restore the routes to the routing
1178: table.
1179:
1180: ** `show interface' show interface's statistics on Linux and BSD with
1181: routing socket.
1182:
1183: ** Now zebra can get MTU value on BSDI/OS.
1184:
1185: * Changes in bgpd

1192: ** Check self AS appeared in received routes.
1193:
1194: ** redistribute route-map support is added.
1195:
1196: ** BGP packet dump feature compatible with MRT.
1197:
1198: * Changes in ripd
1199:
1200: ** Fix bug of `timers basic' command's argument format.
1201:
1202: * Changes in ripngd

1214: ** Many debug feature is added.
1215:
1216: * Changes in zebra-0.81
1217:
1218: ** SNMP support is disabled in default.--enable-snmp option is added
1219: to configure script.
1220:
1221: * Changes in bgpd
1222:
1223: ** Fix FSM bug which introduced in zebra-0.80.
1224:
1225: * Changes in zebra-0.80
1226:
1227: * access-list
1228:
1229: New access-list name space `ipv6 access-list' is added. At the same
1230: time, `access-list' statemant only accepts IPv4 prefix. Please be
1231: careful if you use IPv6 filtering. You will need to change your
1232: configuration. For IPv6 filtering please use `ipv6 access-list'.
1233:
1234: As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
1235: filtering.
1236:
1237: ! zebra-0.7x
1238: access-list DML-net permit 203.181.89.0/24
1239: access-list DML-net permit 3ffe:506::0/32
1240: access-list DML-net deny any
1241: !
1242:
1243: Above configuration is not valid for zebra-08x. Please add `ipv6'
1244: before 'access-list' when you configure IPv6 filtering.
1245:
1246: ! zebra-0.8x
1247: access-list DML-net permit 203.181.89.0/24
1248: access-list DML-net deny any
1249: !
1250: ipv6 access-list DML-net permit 3ffe:506::0/32
1251: ipv6 access-list DML-net deny any
1252: !
1253:
1254: * prefix-list
1255:
1256: And also new prefix-list name space `ipv6 prefix-list' is added. It
1257: is the same as the change of `access-list'. `ip prefix-list' now only
1258: accept IPv4 prefix. It was source of confusion that `ip prefix-list'
1259: can be used both IPv4 and IPv6 filtering. Now name space is separated
1260: to clear the meaning of the filter.
1261:
1262: If you use `ip prefix-list' for IPv6 filtering, please change the
1263: stetement.
1264:
1265: ! zebra-0.7x
1266: ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1267: ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1268: ip prefix-list 6bone-filter seq 12 deny 3ffe::/16
1269: ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1270: ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1271: ip prefix-list 6bone-filter seq 30 deny any
1272: !
1273:
1274: Now user can explicitly configure it as IPv6 prefix-list.
1275:
1276: ! zebra-0.8x
1277: ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1278: ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1279: ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16
1280: ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1281: ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1282: ipv6 prefix-list 6bone-filter seq 30 deny any
1283: !
1284:
1285: * RIP configuration
1286:
1287: If you want to filter only default route (0.0.0.0/0) and permit other
1288: routes, it was hard to do that. Now `ip prefix-list' can be used for
1289: RIP route filtering.
1290:
1291: New statement:
1292:
1293: `distribute-list prefix PLIST_NAME (in|out) IFNAME'
1294:
1295: is added to ripd. So you can configure on eth0 interface accept all
1296: routes other than default routes.
1297:
1298: !
1299: router rip
1300: distribute-list prefix filter-default in eth0
1301: !
1302: ip prefix-list filter-default deny 0.0.0.0/0 le 0
1303: ip prefix-list filter-default permit any
1304: !
1305:
1306: * RIPng configuration
1307:
1308: Same change is done for ripngd. You can use `ipv6 prefix-list' for
1309: filtering.
1310:
1311: !
1312: router ripng
1313: distribute-list prefix filter-default in eth0
1314: !
1315: ipv6 prefix-list filter-default deny ::/0 le 0
1316: ipv6 prefix-list filter-default permit any
1317: !
1318:
1319: * BGP configuration
1320:
1321: So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
1322: done with traditional IPv4 peering statement like blow.
1323:
1324: !
1325: router bgp 7675
1326: neighbor 3ffe:506::1 remote-as 2500
1327: neighbor 3ffe:506::1 prefix-list 6bone-filter out
1328: !
1329:
1330: For separating configuration IPv4 and IPv6, and for retaining Cisco
1331: configuration compatibility, now IPv6 configuration is done by IPv6
1332: specific statement. IPv6 BGP configuration is done by statement which
1333: start from `ipv6 bgp'.
1334:
1335: !
1336: router bgp 7675
1337: !
1338: ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
1339: ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
1340: !
1341:
1342: At the same time some IPv6 specific commands are deleted from IPv4
1343: configuration.
1344:
1345: o redistribute ripng
1346: o redistribute ospf6
1347: o neighbor PEER version BGP_VERSION
1348: o neighbor PEER interface IFNAME
1349:
1350: Those commands are only accepted as like below.
1351:
1352: o ipv6 bgp redistribute ripng
1353: o ipv6 bgp redistribute ospf6
1354: o ipv6 bgp neighbor PEER version BGP_VERSION
1355: o ipv6 bgp neighbor PEER interface IFNAME
1356:
1357: And below new commands are added.
1358:
1359: o ipv6 bgp network IPV6_PREFIX
1360: o ipv6 bgp redistribute static
1361: o ipv6 bgp redistribute connected
1362: o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
1363: o ipv6 bgp neighbor PEER ebgp-multihop [TTL]
1364: o ipv6 bgp neighbor PEER description DESCRIPTION
1365: o ipv6 bgp neighbor PEER shutdown
1366: o ipv6 bgp neighbor PEER route-reflector-client
1367: o ipv6 bgp neighbor PEER update-source IFNAME
1368: o ipv6 bgp neighbor PEER next-hop-self
1369: o ipv6 bgp neighbor PEER timers holdtime <0-65535>
1370: o ipv6 bgp neighbor PEER timers keepalive <0-65535>
1371: o ipv6 bgp neighbor PEER send-community
1372: o ipv6 bgp neighbor PEER weight <0-65535>
1373: o ipv6 bgp neighbor PEER default-originate
1374: o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out)
1375: o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
1376: o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
1377: o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
1378:
1379: And some utility commands are introduced.
1380:
1381: o clear ipv6 bgp [PEER]
1382: o show ipv6 bgp neighbors [PEER]
1383: o show ipv6 bgp summary
1384:
1385: I hope these changes are easy to understand for current Zebra users...
1386:
1387: * To restrict connection to VTY interface.
1388:
1389: It used to be both IPv4 and IPv6 filter can be specified with one
1390: access-list. Then the access-list can be appried to VTY interface
1391: with `access-class' stetement in `line vty' node. Below is example in
1392: zebra-0.7x.
1393:
1394: !
1395: access-list local-only permit 127.0.0.1/32
1396: access-list local-only permit ::1/128
1397: access-list local-only deny any
1398: !
1399: line vty
1400: access-class local-only
1401: !
1402:
1403: Now IPv4 and IPv6 filter have each name space. It is not possible to
1404: specify IPv4 and IPv6 filter with one access-list. For setting IPv6
1405: access-list in `line vty', `ipv6 access-class' statement is
1406: introduced. Let me show the configuration in zebra-0.8x.
1407:
1408: !
1409: access-list local-only permit 127.0.0.1/32
1410: access-list local-only deny any
1411: !
1412: ipv6 access-list local-only permit ::1/128
1413: ipv6 access-list local-only dny any
1414: !
1415: line vty
1416: access-class local-only
1417: ipv6 access-class local-only
1418: !
1419:
1420: * route-map
1421:
1422: New IPv6 related route-map match commands are added.
1423:
1424: o match ipv6 address
1425: o match ipv6 next-hop
1426:
1427: Please change your configuration if you use IP match statement for
1428: IPv6 route.
1429:
1430: zebra-0.7x config
1431: =================
1432: !
1433: access-list all permit any
1434: !
1435: route-map set-nexthop permit 10
1436: match ip address all

1450: !
1451:
1452: * zebra connection
1453:
1454: Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
1455: when the connection fail. Those daemons try to connect zebra every 10
1456: seconds first three trial, then the interval changed to 60 seconds.
1457: After all, if ten connections are fail, protocol daemon give up the
1458: connection to the zebra daemon.
1459:
1460: * SNMP support (is not yet finished)
1461:
1462: Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
1463: agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
1464: and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
1465: compiled with ucd-snmp-3.6.2.
1466:
1467: After applying the patch to ucd-snmp-4.0.1, please configure it with
1468: SMUX module.
1469:
1470: % configure --with-mib-modules=smux
1471:
1472: After compile & install ucd-snmp-4.0.1, you will need to configure
1473: smuxpeer. I'm now using below configuration.
1474:
1475: /usr/local/share/snmp/snmpd.conf
1476: ================================
1477: smuxpeer 1.3.6.1.6.3.1 test
1478:
1479: Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard
1480: coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP.
1481:
1482: * HUP signal treatment
1483:
1484: From zebra-0.80, ripd will reload it's configuration file when ripd
1485: receives HUP signal. Other daemon such as bgpd, ospfd will support
1486: HUP signal treatment soon.
1487:
