3: * Changes in Quagga 0.99.24
4:
5: User-visible changes:
6: - [pimd] New daemon: pimd provides IPv4 PIM-SSM multicast routing.
7: - [bgpd] New feature: "next-hop-self all" to override nexthop on iBGP route
8: reflector setups.
9: - [bgpd] route-maps have a new action "set ipv6 next-hop peer-address"
10: - [bgpd] route-maps have a new action "set as-path prepend last-as"
11: - [bgpd] Update validity checking (particularly MP-BGP / IPv6 routes) was
12: touched up significantly. Please report possible bugs.
13: - [ripd] New feature: RIP for IPv4 now supports equal-cost multipath (ECMP)
14: - [zebra] Multicast RIB support has been extended. It still is IPv4 only.
15: - [zebra] "no link-detect" is now printed in configurations since it won't
16: be the default anymore soon. To retain current behaviour, re-save your
17: configuration after updating to 0.99.24.
18:
19: Distributor-visible changes:
20: - --enable-pimd is added to enable pimd. It is considered experimental, though
21: unless the distribution target is embedded systems with little flash, there
22: is no reason to not include it in packages.
23: - --disable-ipv6 no longer exists as an option. It's 2015, your C library
24: really needs to have IPv6 support by now.
25: - --disable-netlink no longer exists as an option. It didn't work anyway.
26: - --disable-solaris no longer exists as an option. It only controlled some
27: init scripts.
28: - --enable-isisd is now the default.
29: - mrlg.cgi is no longer included (it was severely outdated). It can be found
30: independently at http://mrlg.op-sec.us/
31: - build on Linux with the musl C library should now work
32:
33: * Changes in Quagga 0.99.23
34:
35: Known issues:
36: - [bgpd] setting an extcommunity in a route map on a route that already has
37: an extcommunity attribute will cause bgpd to crash. This issue will be
38: fixed in a followup minor release.
39:
40: User-visible changes:
41: - [lib] Performance enhancements on hashes and timers.
42: - [bgpd] New feature: iBGP TTL security.
43: - [bgpd] New feature: relaxed bestpath criteria for multipath and improved
44: display of multipath routes in "show ip bgp". Scripts parsing this output
45: may need to be updated.
46: - [bgpd] Multiprotocol peerings over IPv6 now try to find a more appropriate
47: IPv4 nexthop by looking at the interface.
48: - [ospf6d] A large amount of changes has been merged for ospf6d. Careful
49: evaluation prior to deployment is recommended.
50: - [zebra] Recursive route support has been overhauled. Scripts parsing
51: "show ip route" output may need adaptation.
52: - [zebra] IPv6 address management has been improved regarding tentative
53: addresses. This is visible in that a freshly configured address will not
54: immediately be marked as usable.
55: - [*] a lot of bugs have been fixed, please refer to the git log
56:
57: * Changes in Quagga 0.99.22
58:
59: - [bgpd] The semantics of default-originate route-map have changed.
60: The route-map is now used to advertise the default route conditionally.
61: The old behaviour which allowed to set attributes on the originated
62: default route is no longer supported.
63: - [bgpd] There is now a replace-as option to neighbor ... local-as ...
64: no-prepend. For details, refer to the user documentation.
65: - [zebra] An FPM interface has been added. This provides an alternate
66: interface to routing information and is geared at OpenFlow & co.
67: - [snmp] AgentX is now supported; the old smux backend is considered
68: deprecated. ospf6d has also had OSPFV3-MIB added.
69: - [*] several issues with configuration save/load/apply have been fixed,
70: in particular on ospf "max-metric router-lsa administrative" and
71: "distribute-list", bgpd "no neighbor activate", isisd "metric-style",
72: - [*] a lot of bugs have been fixed, please refer to the git log
73:
74: * Changes in Quagga 0.99.21
75:
76: - [bgpd] BGP multipath support has been merged
77: - [bgpd] SAFI (Multicast topology) support has been extended to propagate
78: the topology to zebra.
79: - [bgpd] AS path limit functionality has been removed
80: - [babeld] a new routing daemon implementing the BABEL ad-hoc mesh routing
81: protocol has been merged.
82: - [isisd] a major overhaul has been picked up. Please note that isisd is
83: STILL NOT SUITABLE FOR PRODUCTION USE.
84: - [*] a lot of bugs have been fixed, please refer to the git log
85:
86: * Changes in Quagga 0.99.10
87:
88: - [bgpd] 4-byte AS support added
89: - [bgpd] MRT format changes to version 2. Those relying on
90: bgpd MRT table dumps may need to update their tools.
91: - [bgpd] Added new route-map set statement: "as-path exclude"
92: - Zebra RIB updates queue has evolved into a multi-level
93: structure to address RIB consistency issues.
94:
95: * Changes in Quagga 0.99.2
96:
97: - [bgpd] Work queues added to bgpd to split up update processing,
98: particularly beneficial when a peer session goes down. AS_PATH
99: parsing rewritten to be clearer, more robust and ready for 4-byte.
100:
101: - [ripd] Simple authentication is no longer the default authentication
102: mode for ripd. The default is now no-authentication. Any setups which
103: used simple authentication will probably need to update their
104: configuration manually.
105:
106: - [ospfd] 1s dead-interval with sub-second Hellos feature added.
107: SPF timers now specified in milliseconds, and with adaptive
108: hold-time support. RFC3137 Stub-router support added. Default ABR
109: type is now 'cisco'.
110:
111: - Solaris least privileges support added.
112:
113: * Changes in Quagga 0.99.1
114:
115: - Zserv is now buffered via threads and non-blocking in most cases for both
116: clients and zebra, which should improve responsiveness of daemons when
117: they must send many messages to zebra.
118:
119: - 'show thread cpu' now displays both cpu+system and wall-clock time,
120: where getrusage() is available.
121:
122: - Background threads added and workqueue API added, with a
123: 'show work-queues' command. Thread scheduling improved slightly.
124:
125: - Zebra now has a work-queue for RIB processing. See 'show work-queues' in
126: the zebra daemon vty.
127:
128: - Support for interface renaming on Linux netlink systems.
129:
130: - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip
131: route-source" command.
132:
133: - Automatic logging of backtraces should daemons crash to assist in
134: diagnosis. See the documentation for more information on configuring
135: logging correctly, and set --enable-gcc-rdynamic if compiling with gcc.
136:
137: * Changes in Quagga 0.98.0
138:
139: - Logging facilities upgraded. One can now specify a severity level
140: for each logging destination. And a new "show logging" command gives
141: thorough information on the current logging system configuration.
142:
143: - Watchquagga daemon added. This is not well tested yet. Please try
144: monitor mode first before enabling restart features. It is important
145: to make sure that the various timers are configured with appropriate
146: values for your site.
147:
148: - BGP route-server support added. See the texinfo documentation.
149:
150: - OSPF API initialisation is disabled by default even if compiled in. You
151: can enable it with -a/--apiserver command line switch.
152:
153: - "write-config integrated" vtysh command replaced with "service
154: integrated-vtysh-config" command.
155:
156: - Router id is now handled by zebra daemon and all daemons receive changes
157: from it. Router id can be overriden in daemons' configurations of course.
158: To fix common router id in zebra daemon you can either install non-127
159: address on loopback or use "router-id x.x.x.x" command.
160:
161: - "secondary" keyword is removed from ip address configuration. All
162: supported OS'es have their own vision what's secondary address and
163: how to handle it.
164:
165: - Zebra no longer enables forwarding by default. If you rely on zebra to
166: enable forwarding make sure to add '<ip|ip6> forwarding' statements
167: to your zebra configuration file.
168:
169: - All libraries are built and used shared, on platforms where libtool
170: supports shared libraries.
171:
172: - Router advertisement syntax is changed. In usual cases (if you didn't do
173: any fancy stuff) it's enough to change lines in configuration from:
174: "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link"
175: to:
176: "ipv6 nd prefix X:X:X:X::/X"
177:
178: All router advertisement options are documented in texi documentation.
179:
180: - --enable-nssa configure switch is removed. NSSA support is stable enough.
181:
182: - Daemons don't look at current directory for config file any more.
183:
184: * Changes in Quagga 0.96.5
185:
186: - include files are installed in $(prefix)/include/quagga. Programs
187: building against these includes should -I$(prefix)/include and e.g.
188: #include <quagga/routemap.h>
189:
190: - New option --enable-exampledir puts example files in a separate
191: directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules
192: compliance.
193:
194: - New configure options --enable-configfile-mask and
195: --enable-logfile-mask to set umask values for config and log
196: values. Masks default to 0600, matching previous behavior.
197:
198: - Import current CVS isisd from SourceForge, then merge it with
199: the Quagga's Framework.
200:
201: * Changes in Quagga 0.96.4
202:
203: - Further fixes to ospfd, some relating to the PtP revert. Interface
204: lookups should be a lot more robust now.
205:
206: - Fix for a remote triggerable crash in vty layer.
207:
208: - Improvements to ripd, and addition of split horizon support.
209:
210: - Improved bgpd table support, now dumps at time of day intervals rather
211: than time from startup intervals. Much improved support for IPv6 table
212: dumps. show commands for views improved.
213:
214: * Changes in Quagga 0.96.3
215:
216: - revert the 'generic PtP' patch. Means Quagga will no longer work with
217: FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs
218: which the PtP patch introduced.
219:
220: * Changes in Quagga 0.96.2
221:
222: - Fix crash in ospfd

282: * Changes in bgpd
283:
284: ** IPv4 multicast and IPv6 unicast configuration is changed to so
285: called new config. All of AFI and SAFI specific configuration is
286: moved to "address-family" node. When you have many IPv6 only
287: configuration, you will see many "no neighbor X:X::X:X activate" line
288: in your configuration to disable IPv4 unicast NLRI exchange. In that
289: case please use "no bgp default ipv4-unicast" command to suppress the
290: output. Until zebra-0.93, old config is still left for compatibility.

448: in old RIB code.
449:
450: *** Static route with distance value
451:
452: Static route can be specified with administrative distance. The
453: distance value 255 means it is not installed into the kernel.
454: Default value of distance for static route is 1.
455:
456: ip route A.B.C.D/M A.B.C.D <1-255>
457: ip route A.B.C.D/M IFNAME <1-255>
458:
459: If the least distance value's route's nexthop are unreachable,
460: select the least distance value route which has reachable nexthop is
461: selected.
462:
463: ip route 0.0.0.0/0 10.0.0.1
464: ip route 0.0.0.0/0 11.0.0.1 2
465:
466: In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
467: reachable. The route with nexthop 11.0.0.1 will be installed into
468: forwarding table.
469:
470: zebra> show ip route
471: S>* 0.0.0.0/0 [2/0] via 11.0.0.1
472: S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
473:
474: If the nexthop is unreachable "inactive" is displayed. You can
475: specify any string to IFNAME. There is no need of the interface is
476: there when you configure the route.
477:
478: ip route 1.1.1.1/32 ppp0
479:
480: When ppp0 comes up, the route is installed properly.
481:
482: *** Multiple nexthop routes for one prefix
483:
484: Multiple nexthop routes can be specified for one prefix. Even the
485: kernel support only one nexthop for one prefix user can configure
486: multiple nexthop.
487:
488: When you configure routes like below, prefix 10.0.0.1 has three
489: nexthop.
490:
491: ip route 10.0.0.1/32 10.0.0.2
492: ip route 10.0.0.1/32 10.0.0.3
493: ip route 10.0.0.1/32 eth0
494:
495: If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
496: is reachable, then the last route is installed into the kernel.
497:
498: zebra> show ip route
499: S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
500: via 10.0.0.3 inactive
501: * is directly connected, eth0
502:
503: '*' means this nexthop is installed into the kernel.
504:
505: *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
506:
507: When the kernel support multipath, zebra can install multipath
508: routes into the kernel. Before doing that please make it sure that
509: setting --enable-multipath=ARG to configure script. ARG must be digit
510: value. When specify 0 to ARG, there is no limitation of the number
511: of the multipath. Currently only GNU/Linux with netlink interface is
512: supported.
513:
514: ip route 10.0.0.1/32 10.0.0.2
515: ip route 10.0.0.1/32 10.0.0.3
516: ip route 10.0.0.1/32 eth0
517:
518: zebra> show ip route

1303: ** SNMP support is disabled in default.--enable-snmp option is added
1304: to configure script.
1305:
1306: * Changes in bgpd
1307:
1308: ** Fix FSM bug which introduced in zebra-0.80.
1309:
1310: * Changes in zebra-0.80
1311:
1312: * access-list
1313:
1314: New access-list name space `ipv6 access-list' is added. At the same
1315: time, `access-list' statemant only accepts IPv4 prefix. Please be
1316: careful if you use IPv6 filtering. You will need to change your
1317: configuration. For IPv6 filtering please use `ipv6 access-list'.
1318:
1319: As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
1320: filtering.
1321:
1322: ! zebra-0.7x
1323: access-list DML-net permit 203.181.89.0/24
1324: access-list DML-net permit 3ffe:506::0/32
1325: access-list DML-net deny any
1326: !
1327:
1328: Above configuration is not valid for zebra-08x. Please add `ipv6'
1329: before 'access-list' when you configure IPv6 filtering.
1330:
1331: ! zebra-0.8x
1332: access-list DML-net permit 203.181.89.0/24
1333: access-list DML-net deny any
1334: !
1335: ipv6 access-list DML-net permit 3ffe:506::0/32
1336: ipv6 access-list DML-net deny any
1337: !
1338:
1339: * prefix-list
1340:
1341: And also new prefix-list name space `ipv6 prefix-list' is added. It
1342: is the same as the change of `access-list'. `ip prefix-list' now only
1343: accept IPv4 prefix. It was source of confusion that `ip prefix-list'
1344: can be used both IPv4 and IPv6 filtering. Now name space is separated
1345: to clear the meaning of the filter.
1346:
1347: If you use `ip prefix-list' for IPv6 filtering, please change the
1348: stetement.
1349:
1350: ! zebra-0.7x
1351: ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1352: ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
1353: ip prefix-list 6bone-filter seq 12 deny 3ffe::/16

1355: ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1356: ip prefix-list 6bone-filter seq 30 deny any
1357: !
1358:
1359: Now user can explicitly configure it as IPv6 prefix-list.
1360:
1361: ! zebra-0.8x
1362: ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
1363: ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28

1365: ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
1366: ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
1367: ipv6 prefix-list 6bone-filter seq 30 deny any
1368: !
1369:
1370: * RIP configuration
1371:
1372: If you want to filter only default route (0.0.0.0/0) and permit other
1373: routes, it was hard to do that. Now `ip prefix-list' can be used for
1374: RIP route filtering.
1375:
1376: New statement:
1377:
1378: `distribute-list prefix PLIST_NAME (in|out) IFNAME'
1379:
1380: is added to ripd. So you can configure on eth0 interface accept all
1381: routes other than default routes.
1382:
1383: !
1384: router rip
1385: distribute-list prefix filter-default in eth0
1386: !
1387: ip prefix-list filter-default deny 0.0.0.0/0 le 0
1388: ip prefix-list filter-default permit any
1389: !
1390:
1391: * RIPng configuration
1392:
1393: Same change is done for ripngd. You can use `ipv6 prefix-list' for
1394: filtering.
1395:
1396: !
1397: router ripng
1398: distribute-list prefix filter-default in eth0
1399: !
1400: ipv6 prefix-list filter-default deny ::/0 le 0
1401: ipv6 prefix-list filter-default permit any
1402: !
1403:
1404: * BGP configuration
1405:
1406: So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
1407: done with traditional IPv4 peering statement like blow.
1408:
1409: !
1410: router bgp 7675
1411: neighbor 3ffe:506::1 remote-as 2500
1412: neighbor 3ffe:506::1 prefix-list 6bone-filter out
1413: !
1414:
1415: For separating configuration IPv4 and IPv6, and for retaining Cisco
1416: configuration compatibility, now IPv6 configuration is done by IPv6
1417: specific statement. IPv6 BGP configuration is done by statement which
1418: start from `ipv6 bgp'.
1419:
1420: !
1421: router bgp 7675
1422: !
1423: ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
1424: ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
1425: !
1426:
1427: At the same time some IPv6 specific commands are deleted from IPv4
1428: configuration.
1429:
1430: o redistribute ripng
1431: o redistribute ospf6
1432: o neighbor PEER version BGP_VERSION
1433: o neighbor PEER interface IFNAME
1434:
1435: Those commands are only accepted as like below.
1436:
1437: o ipv6 bgp redistribute ripng
1438: o ipv6 bgp redistribute ospf6
1439: o ipv6 bgp neighbor PEER version BGP_VERSION
1440: o ipv6 bgp neighbor PEER interface IFNAME
1441:
1442: And below new commands are added.
1443:
1444: o ipv6 bgp network IPV6_PREFIX
1445: o ipv6 bgp redistribute static
1446: o ipv6 bgp redistribute connected
1447: o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
1448: o ipv6 bgp neighbor PEER ebgp-multihop [TTL]
1449: o ipv6 bgp neighbor PEER description DESCRIPTION
1450: o ipv6 bgp neighbor PEER shutdown
1451: o ipv6 bgp neighbor PEER route-reflector-client

1453: o ipv6 bgp neighbor PEER next-hop-self
1454: o ipv6 bgp neighbor PEER timers holdtime <0-65535>
1455: o ipv6 bgp neighbor PEER timers keepalive <0-65535>
1456: o ipv6 bgp neighbor PEER send-community
1457: o ipv6 bgp neighbor PEER weight <0-65535>
1458: o ipv6 bgp neighbor PEER default-originate
1459: o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out)
1460: o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
1461: o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
1462: o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
1463:
1464: And some utility commands are introduced.
1465:
1466: o clear ipv6 bgp [PEER]
1467: o show ipv6 bgp neighbors [PEER]
1468: o show ipv6 bgp summary
1469:
1470: I hope these changes are easy to understand for current Zebra users...
1471:
1472: * To restrict connection to VTY interface.
1473:
1474: It used to be both IPv4 and IPv6 filter can be specified with one
1475: access-list. Then the access-list can be appried to VTY interface
1476: with `access-class' stetement in `line vty' node. Below is example in
1477: zebra-0.7x.
1478:
1479: !
1480: access-list local-only permit 127.0.0.1/32
1481: access-list local-only permit ::1/128
1482: access-list local-only deny any
1483: !
1484: line vty
1485: access-class local-only
1486: !
1487:
1488: Now IPv4 and IPv6 filter have each name space. It is not possible to
1489: specify IPv4 and IPv6 filter with one access-list. For setting IPv6
1490: access-list in `line vty', `ipv6 access-class' statement is
1491: introduced. Let me show the configuration in zebra-0.8x.
1492:
1493: !
1494: access-list local-only permit 127.0.0.1/32
1495: access-list local-only deny any
1496: !
1497: ipv6 access-list local-only permit ::1/128
1498: ipv6 access-list local-only dny any
1499: !
1500: line vty
1501: access-class local-only
1502: ipv6 access-class local-only
1503: !
1504:
1505: * route-map
1506:
1507: New IPv6 related route-map match commands are added.
1508:
1509: o match ipv6 address
1510: o match ipv6 next-hop
1511:
1512: Please change your configuration if you use IP match statement for
1513: IPv6 route.
1514:
1515: zebra-0.7x config
1516: =================
1517: !
1518: access-list all permit any
1519: !

1536:
1537: * zebra connection
1538:
1539: Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
1540: when the connection fail. Those daemons try to connect zebra every 10
1541: seconds first three trial, then the interval changed to 60 seconds.
1542: After all, if ten connections are fail, protocol daemon give up the
1543: connection to the zebra daemon.
1544:
1545: * SNMP support (is not yet finished)
1546:
1547: Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
1548: agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
1549: and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
1550: compiled with ucd-snmp-3.6.2.
1551:
1552: After applying the patch to ucd-snmp-4.0.1, please configure it with
1553: SMUX module.
1554:
1555: % configure --with-mib-modules=smux
1556:
1557: After compile & install ucd-snmp-4.0.1, you will need to configure
1558: smuxpeer. I'm now using below configuration.
1559:
1560: /usr/local/share/snmp/snmpd.conf
1561: ================================
1562: smuxpeer 1.3.6.1.6.3.1 test
1563:
1564: Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard
1565: coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP.
1566:
1567: * HUP signal treatment
1568:
1569: From zebra-0.80, ripd will reload it's configuration file when ripd
1570: receives HUP signal. Other daemon such as bgpd, ospfd will support
1571: HUP signal treatment soon.
1572:
1573: * Changes in zebra-0.79
1574:
1575: * Changes in zebra
1576:
1577: ** Broadcast address setting on Linux box bug is fixed.
1578:
1579: ** Protocol daemon can install connected IPv6 route into the kernel.
1580:
1581: ** Now zebra can handle blackhole route.
1582:
1583: * Changes in ripd
1584:
1585: ** Add route-map feature for RIP protocol.
1586:
1587: ** In case of RIP version 2 routing table entry has IPv4 address and
1588: netmask pair which host part bit is on, ignore the entry.
1589:
1590: * Changes in ripngd
