1.1.1.3 ! misho 3: * Changes in Quagga 0.99.22
! 4:
! 5: - [bgpd] The semantics of default-originate route-map have changed.
! 6: The route-map is now used to advertise the default route conditionally.
! 7: The old behaviour which allowed to set attributes on the originated
! 8: default route is no longer supported.
! 9: - [bgpd] There is now a replace-as option to neighbor ... local-as ...
! 10: no-prepend. For details, refer to the user documentation.
! 11: - [zebra] An FPM interface has been added. This provides an alternate
! 12: interface to routing information and is geared at OpenFlow & co.
! 13: - [snmp] AgentX is now supported; the old smux backend is considered
! 14: deprecated. ospf6d has also had OSPFV3-MIB added.
! 15: - [*] several issues with configuration save/load/apply have been fixed,
! 16: in particular on ospf "max-metric router-lsa administrative" and
! 17: "distribute-list", bgpd "no neighbor activate", isisd "metric-style",
! 18: - [*] a lot of bugs have been fixed, please refer to the git log
! 19:
1.1.1.2 misho 20: * Changes in Quagga 0.99.21
21:
22: - [bgpd] BGP multipath support has been merged
23: - [bgpd] SAFI (Multicast topology) support has been extended to propagate
24: the topology to zebra.
25: - [bgpd] AS path limit functionality has been removed
26: - [babeld] a new routing daemon implementing the BABEL ad-hoc mesh routing
27: protocol has been merged.
28: - [isisd] a major overhaul has been picked up. Please note that isisd is
29: STILL NOT SUITABLE FOR PRODUCTION USE.
30: - [*] a lot of bugs have been fixed, please refer to the git log
31:
1.1 misho 32: * Changes in Quagga 0.99.10
33:
34: - [bgpd] 4-byte AS support added
35: - [bgpd] MRT format changes to version 2. Those relying on
36: bgpd MRT table dumps may need to update their tools.
37: - [bgpd] Added new route-map set statement: "as-path exclude"
38: - Zebra RIB updates queue has evolved into a multi-level
39: structure to address RIB consistency issues.
40:
41: * Changes in Quagga 0.99.2
42:
43: - [bgpd] Work queues added to bgpd to split up update processing,
44: particularly beneficial when a peer session goes down. AS_PATH
45: parsing rewritten to be clearer, more robust and ready for 4-byte.
46:
47: - [ripd] Simple authentication is no longer the default authentication
48: mode for ripd. The default is now no-authentication. Any setups which
49: used simple authentication will probably need to update their
50: configuration manually.
51:
52: - [ospfd] 1s dead-interval with sub-second Hellos feature added.
53: SPF timers now specified in milliseconds, and with adaptive
54: hold-time support. RFC3137 Stub-router support added. Default ABR
55: type is now 'cisco'.
56:
57: - Solaris least privileges support added.
58:
59: * Changes in Quagga 0.99.1
60:
61: - Zserv is now buffered via threads and non-blocking in most cases for both
62: clients and zebra, which should improve responsiveness of daemons when
63: they must send many messages to zebra.
64:
65: - 'show thread cpu' now displays both cpu+system and wall-clock time,
66: where getrusage() is available.
67:
68: - Background threads added and workqueue API added, with a
69: 'show work-queues' command. Thread scheduling improved slightly.
70:
71: - Zebra now has a work-queue for RIB processing. See 'show work-queues' in
72: the zebra daemon vty.
73:
74: - Support for interface renaming on Linux netlink systems.
75:
76: - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip
77: route-source" command.
78:
79: - Automatic logging of backtraces should daemons crash to assist in
80: diagnosis. See the documentation for more information on configuring
81: logging correctly, and set --enable-gcc-rdynamic if compiling with gcc.
82:
83: * Changes in Quagga 0.98.0
84:
85: - Logging facilities upgraded. One can now specify a severity level
86: for each logging destination. And a new "show logging" command gives
87: thorough information on the current logging system configuration.
88:
89: - Watchquagga daemon added. This is not well tested yet. Please try
90: monitor mode first before enabling restart features. It is important
91: to make sure that the various timers are configured with appropriate
92: values for your site.
93:
94: - BGP route-server support added. See the texinfo documentation.
95:
96: - OSPF API initialisation is disabled by default even if compiled in. You
97: can enable it with -a/--apiserver command line switch.
98:
99: - "write-config integrated" vtysh command replaced with "service
100: integrated-vtysh-config" command.
101:
102: - Router id is now handled by zebra daemon and all daemons receive changes
103: from it. Router id can be overriden in daemons' configurations of course.
104: To fix common router id in zebra daemon you can either install non-127
105: address on loopback or use "router-id x.x.x.x" command.
106:
107: - "secondary" keyword is removed from ip address configuration. All
108: supported OS'es have their own vision what's secondary address and
109: how to handle it.
110:
111: - Zebra no longer enables forwarding by default. If you rely on zebra to
112: enable forwarding make sure to add '<ip|ip6> forwarding' statements
113: to your zebra configuration file.
114:
115: - All libraries are built and used shared, on platforms where libtool
116: supports shared libraries.
117:
118: - Router advertisement syntax is changed. In usual cases (if you didn't do
119: any fancy stuff) it's enough to change lines in configuration from:
120: "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link"
121: to:
122: "ipv6 nd prefix X:X:X:X::/X"
123:
124: All router advertisement options are documented in texi documentation.
125:
126: - --enable-nssa configure switch is removed. NSSA support is stable enough.
127:
128: - Daemons don't look at current directory for config file any more.
129:
130: * Changes in Quagga 0.96.5
131:
132: - include files are installed in $(prefix)/include/quagga. Programs
133: building against these includes should -I$(prefix)/include and e.g.
134: #include <quagga/routemap.h>
135:
136: - New option --enable-exampledir puts example files in a separate
137: directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules
138: compliance.
139:
140: - New configure options --enable-configfile-mask and
141: --enable-logfile-mask to set umask values for config and log
142: values. Masks default to 0600, matching previous behavior.
143:
144: - Import current CVS isisd from SourceForge, then merge it with
145: the Quagga's Framework.
146:
147: * Changes in Quagga 0.96.4
148:
149: - Further fixes to ospfd, some relating to the PtP revert. Interface
150: lookups should be a lot more robust now.
151:
152: - Fix for a remote triggerable crash in vty layer.
153:
154: - Improvements to ripd, and addition of split horizon support.
155:
156: - Improved bgpd table support, now dumps at time of day intervals rather
157: than time from startup intervals. Much improved support for IPv6 table
158: dumps. show commands for views improved.
159:
160: * Changes in Quagga 0.96.3
161:
162: - revert the 'generic PtP' patch. Means Quagga will no longer work with
163: FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs
164: which the PtP patch introduced.
165:
166: * Changes in Quagga 0.96.2
167:
168: - Fix crash in ospfd

227:
228: * Changes in bgpd
229:
230: ** IPv4 multicast and IPv6 unicast configuration is changed to so
231: called new config. All of AFI and SAFI specific configuration is
232: moved to "address-family" node. When you have many IPv6 only
233: configuration, you will see many "no neighbor X:X::X:X activate" line
234: in your configuration to disable IPv4 unicast NLRI exchange. In that
235: case please use "no bgp default ipv4-unicast" command to suppress the
236: output. Until zebra-0.93, old config is still left for compatibility.

393: zebra. New RIB has many new features and fixed some bugs which exist
394: in old RIB code.
395:
396: *** Static route with distance value
397:
398: Static route can be specified with administrative distance. The
399: distance value 255 means it is not installed into the kernel.
400: Default value of distance for static route is 1.
401:
402: ip route A.B.C.D/M A.B.C.D <1-255>
403: ip route A.B.C.D/M IFNAME <1-255>
404:
405: If the least distance value's route's nexthop are unreachable,
406: select the least distance value route which has reachable nexthop is
407: selected.
408:
409: ip route 0.0.0.0/0 10.0.0.1
410: ip route 0.0.0.0/0 11.0.0.1 2
411:
412: In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
413: reachable. The route with nexthop 11.0.0.1 will be installed into
414: forwarding table.
415:
416: zebra> show ip route
417: S>* 0.0.0.0/0 [2/0] via 11.0.0.1
418: S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
419:
420: If the nexthop is unreachable "inactive" is displayed. You can
421: specify any string to IFNAME. There is no need of the interface is
422: there when you configure the route.
423:
424: ip route 1.1.1.1/32 ppp0
425:
426: When ppp0 comes up, the route is installed properly.
427:
428: *** Multiple nexthop routes for one prefix
429:
430: Multiple nexthop routes can be specified for one prefix. Even the
431: kernel support only one nexthop for one prefix user can configure
432: multiple nexthop.
433:
434: When you configure routes like below, prefix 10.0.0.1 has three
435: nexthop.
436:
437: ip route 10.0.0.1/32 10.0.0.2
438: ip route 10.0.0.1/32 10.0.0.3
439: ip route 10.0.0.1/32 eth0
440:
441: If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
442: is reachable, then the last route is installed into the kernel.
443:
444: zebra> show ip route
445: S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
446: via 10.0.0.3 inactive
447: * is directly connected, eth0
448:
449: '*' means this nexthop is installed into the kernel.
450:
451: *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
452:
453: When the kernel support multipath, zebra can install multipath
454: routes into the kernel. Before doing that please make it sure that
455: setting --enable-multipath=ARG to configure script. ARG must be digit
456: value. When specify 0 to ARG, there is no limitation of the number
457: of the multipath. Currently only GNU/Linux with netlink interface is
458: supported.
459:
460: ip route 10.0.0.1/32 10.0.0.2
461: ip route 10.0.0.1/32 10.0.0.3
462: ip route 10.0.0.1/32 eth0
463:
464: zebra> show ip route
465: S>* 10.0.0.1/32 [1/0] via 10.0.0.2
466: * via 10.0.0.3
467: is directly connected, eth0
468:
469: *** Kernel message delete installed route.
470:
471: After zebra install static or dynamic route into the kernel.
472:
473: R>* 0.0.0.0/0 [120/3] via 10.0.0.1
474:
475: If you delete this route outside zebra, old zebra does not reinstall
476: route again. Now the route is re-processed and properly reinstall the
477: static or dynamic route into the kernel.
478:
479: ** GNU/Linux netlink socket handling is improved to fix race condition
480: between kernel message and user command responce.
481:
482: * Changes in bgpd
483:
484: ** Add show neighbor's routes command.
485:
486: "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes"
487: "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes"
488: "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes"
489: "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes"
490:
491: ** BGP passive peer support problem is fixed.
492:
493: ** Redistributed IGP nexthop is passed to BGP nexthop.
494:
495: ** On multiaccess media, if the nexthop is reachable nexthop is passed
496: as it is.
497:
498: ** Remove zebra-0.88 compatibility commands.
499:
500: "match ip prefix-list WORD"
501: "match ipv6 prefix-list WORD"
502:
503: Instead of above please use below commands.
504:
505: "match ip address prefix-list WORD"
506: "match ipv6 address prefix-list WORD"
507:
508: ** Fix bug of holdtimer is not reset when bgp cleared.
509:
510: ** "show ip bgp summary" display peer establish/drop count.
511:
512: ** Change "match ip next-hop" argument from IP address to access-list
513: name.
514:
515: ** When "bgp enforce-first-as" is enabled, check EBGP peer's update
516: has it's AS number in the first AS number in AS sequence.
517:
518: ** New route-map command "set community-delete COMMUNITY-LIST" is
519: added. Community matched the CoMMUNITY-LIST is removed from the
520: community.
521:
522: ** BGP-MIB implementation is finished.
523:
524: ** When BGP connection comes from unconfigured IP address, close
525: socket immediately.
526:
527: ** Do not compare router ID when the routes comes from EBGP peer.
528: When originator ID is same, take shorter cluster-list route. If

1107: * Changes in lib
1108:
1109: ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada
1110: <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address,
1111: "X:X::X:X/M" for IPv6 prefix. You can use it like this.
1112:
1113: DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>")
1114:
1115: ** VTY configuration is locked during configuration. This is for
1116: avoiding unconditional crush from two terminals modify the
1117: configuration at the same time. "who" command shows which termnal
1118: lock the configuration. VTY which has '*' character at the head of
1119: line is locking the configuration.
1120:
1121: ** Old logging functions are removed. Functions like
1122: log_open,log_close,openlog are deleted. Instead of that please use
1123: zlog_* functions. zvlog_* used in ospf6d are deleted also.
1124:
1125: ** "terminal monitor" command is added. "no terminal monitor" is for
1126: disabling. This command simply display logging information to the

1142:
1143: ** "no neighbor port PORT" command is added.
1144:
1145: ** To conform RFC1771, "neighbor PEER send-community" is default
1146: behavior. If you want to disable sending community attribute,
1147: please specify "no neighbor PEER send-community" to the peer.
1148:
1149: ** "neighbor maximum-prefix NUMBER" command is added.
1150:
1151: ** Multi-protocol extention NLRI is proceeded only when the peer is
1152: configured proper Address Family and Subsequent Address Family. If
1153: not, those NLRI are simply ignored.
1154:
1155: ** Aggregate-address support is improved. Currently below commands
1156: works.

1185:
1186: * bgpd
1187:
1188: ** Serious bug fix about fetching global and link-local address at the
1189: same time. Due to this bug, corrupted IPv6 prefix is generated. If

1250: to configure script.
1251:
1252: * Changes in bgpd
1253:
1254: ** Fix FSM bug which introduced in zebra-0.80.
1255:
1256: * Changes in zebra-0.80
1257:
1258: * access-list
1259:
1260: New access-list name space `ipv6 access-list' is added. At the same
1261: time, `access-list' statemant only accepts IPv4 prefix. Please be
1262: careful if you use IPv6 filtering. You will need to change your
1263: configuration. For IPv6 filtering please use `ipv6 access-list'.
1264:
1265: As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
1266: filtering.
1267:
1268: ! zebra-0.7x
1269: access-list DML-net permit 203.181.89.0/24
1270: access-list DML-net permit 3ffe:506::0/32
1271: access-list DML-net deny any
1272: !
1273:
1274: Above configuration is not valid for zebra-08x. Please add `ipv6'
1275: before 'access-list' when you configure IPv6 filtering.
1276:
1277: ! zebra-0.8x
1278: access-list DML-net permit 203.181.89.0/24
1279: access-list DML-net deny any
1280: !
1281: ipv6 access-list DML-net permit 3ffe:506::0/32
1282: ipv6 access-list DML-net deny any
1283: !
1284:
1285: * prefix-list
1286:
1287: And also new prefix-list name space `ipv6 prefix-list' is added. It
1288: is the same as the change of `access-list'. `ip prefix-list' now only
1289: accept IPv4 prefix. It was source of confusion that `ip prefix-list'
1290: can be used both IPv4 and IPv6 filtering. Now name space is separated
1291: to clear the meaning of the filter.
1292:
1293: If you use `ip prefix-list' for IPv6 filtering, please change the
1294: stetement.
1295:
1296: ! zebra-0.7x
1297: ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1298: ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1299: ip prefix-list 6bone-filter seq 12 deny 3ffe::/16
1300: ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1301: ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1302: ip prefix-list 6bone-filter seq 30 deny any
1303: !
1304:
1305: Now user can explicitly configure it as IPv6 prefix-list.
1306:
1307: ! zebra-0.8x
1308: ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1309: ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1310: ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16
1311: ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1312: ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1313: ipv6 prefix-list 6bone-filter seq 30 deny any
1314: !
1315:
1316: * RIP configuration
1317:
1318: If you want to filter only default route (0.0.0.0/0) and permit other
1319: routes, it was hard to do that. Now `ip prefix-list' can be used for
1320: RIP route filtering.
1321:
1322: New statement:
1323:
1324: `distribute-list prefix PLIST_NAME (in|out) IFNAME'
1325:
1326: is added to ripd. So you can configure on eth0 interface accept all
1327: routes other than default routes.
1328:
1329: !
1330: router rip
1331: distribute-list prefix filter-default in eth0
1332: !
1333: ip prefix-list filter-default deny 0.0.0.0/0 le 0
1334: ip prefix-list filter-default permit any
1335: !
1336:
1337: * RIPng configuration
1338:
1339: Same change is done for ripngd. You can use `ipv6 prefix-list' for
1340: filtering.
1341:
1342: !
1343: router ripng
1344: distribute-list prefix filter-default in eth0
1345: !
1346: ipv6 prefix-list filter-default deny ::/0 le 0
1347: ipv6 prefix-list filter-default permit any
1348: !
1349:
1350: * BGP configuration
1351:
1352: So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
1353: done with traditional IPv4 peering statement like blow.
1354:
1355: !
1356: router bgp 7675
1357: neighbor 3ffe:506::1 remote-as 2500
1358: neighbor 3ffe:506::1 prefix-list 6bone-filter out
1359: !
1360:
1361: For separating configuration IPv4 and IPv6, and for retaining Cisco
1362: configuration compatibility, now IPv6 configuration is done by IPv6
1363: specific statement. IPv6 BGP configuration is done by statement which
1364: start from `ipv6 bgp'.
1365:
1366: !
1367: router bgp 7675
1368: !
1369: ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
1370: ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
1371: !
1372:
1373: At the same time some IPv6 specific commands are deleted from IPv4
1374: configuration.
1375:
1376: o redistribute ripng
1377: o redistribute ospf6
1378: o neighbor PEER version BGP_VERSION
1379: o neighbor PEER interface IFNAME
1380:
1381: Those commands are only accepted as like below.
1382:
1383: o ipv6 bgp redistribute ripng
1384: o ipv6 bgp redistribute ospf6
1385: o ipv6 bgp neighbor PEER version BGP_VERSION
1386: o ipv6 bgp neighbor PEER interface IFNAME
1387:
1388: And below new commands are added.
1389:
1390: o ipv6 bgp network IPV6_PREFIX
1391: o ipv6 bgp redistribute static
1392: o ipv6 bgp redistribute connected
1393: o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
1394: o ipv6 bgp neighbor PEER ebgp-multihop [TTL]
1395: o ipv6 bgp neighbor PEER description DESCRIPTION
1396: o ipv6 bgp neighbor PEER shutdown
1397: o ipv6 bgp neighbor PEER route-reflector-client
1398: o ipv6 bgp neighbor PEER update-source IFNAME
1399: o ipv6 bgp neighbor PEER next-hop-self
1400: o ipv6 bgp neighbor PEER timers holdtime <0-65535>
1401: o ipv6 bgp neighbor PEER timers keepalive <0-65535>
1402: o ipv6 bgp neighbor PEER send-community
1403: o ipv6 bgp neighbor PEER weight <0-65535>
1404: o ipv6 bgp neighbor PEER default-originate
1405: o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out)
1406: o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
1407: o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
1408: o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
1409:
1410: And some utility commands are introduced.
1411:
1412: o clear ipv6 bgp [PEER]
1413: o show ipv6 bgp neighbors [PEER]
1414: o show ipv6 bgp summary
1415:
1416: I hope these changes are easy to understand for current Zebra users...
1417:
1418: * To restrict connection to VTY interface.
1419:
1420: It used to be both IPv4 and IPv6 filter can be specified with one
1421: access-list. Then the access-list can be appried to VTY interface
1422: with `access-class' stetement in `line vty' node. Below is example in
1423: zebra-0.7x.
1424:
1425: !
1426: access-list local-only permit 127.0.0.1/32
1427: access-list local-only permit ::1/128
1428: access-list local-only deny any
1429: !
1430: line vty
1431: access-class local-only
1432: !
1433:
1434: Now IPv4 and IPv6 filter have each name space. It is not possible to
1435: specify IPv4 and IPv6 filter with one access-list. For setting IPv6
1436: access-list in `line vty', `ipv6 access-class' statement is
1437: introduced. Let me show the configuration in zebra-0.8x.
1438:
1439: !
1440: access-list local-only permit 127.0.0.1/32
1441: access-list local-only deny any
1442: !
1443: ipv6 access-list local-only permit ::1/128
1444: ipv6 access-list local-only dny any
1445: !
1446: line vty
1447: access-class local-only
1448: ipv6 access-class local-only
1449: !
1450:
1451: * route-map
1452:
1453: New IPv6 related route-map match commands are added.
1454:
1455: o match ipv6 address
1456: o match ipv6 next-hop
1457:
1458: Please change your configuration if you use IP match statement for
1459: IPv6 route.
1460:
1461: zebra-0.7x config
1462: =================
1463: !
1464: access-list all permit any
1465: !
1466: route-map set-nexthop permit 10
1467: match ip address all

1481: !
1482:
1483: * zebra connection
1484:
1485: Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
1486: when the connection fail. Those daemons try to connect zebra every 10
1487: seconds first three trial, then the interval changed to 60 seconds.
1488: After all, if ten connections are fail, protocol daemon give up the
1489: connection to the zebra daemon.
1490:
1491: * SNMP support (is not yet finished)
1492:
1493: Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
1494: agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
1495: and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
1496: compiled with ucd-snmp-3.6.2.
1497:
1498: After applying the patch to ucd-snmp-4.0.1, please configure it with
1499: SMUX module.
1500:
1501: % configure --with-mib-modules=smux
1502:
1503: After compile & install ucd-snmp-4.0.1, you will need to configure
1504: smuxpeer. I'm now using below configuration.
1505:
1506: /usr/local/share/snmp/snmpd.conf
1507: ================================
1508: smuxpeer 1.3.6.1.6.3.1 test
1509:
1510: Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard
1511: coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP.
1512:
1513: * HUP signal treatment
1514:
1515: From zebra-0.80, ripd will reload it's configuration file when ripd
1516: receives HUP signal. Other daemon such as bgpd, ospfd will support
1517: HUP signal treatment soon.
1518:
