Annotation of embedaddon/quagga/NEWS, revision 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.

! 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.

! 351:
! 352: ** Fix PointoPoint interface network bug. The destination network
! 353: should be installed into routing table instead of local network.
! 354:
! 355: ** Metric value is reflected to kernel routing table.
! 356:
! 357: ** "show ip route" display uptime of RIP,OSPF,BGP routes.
! 358:
! 359: ** New RIB implementation is added.
! 360:
! 361: Now we have enhanced RIB (routing information base) implementation in
! 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.
! 480:
! 481: ** Change "match ip next-hop" argument from IP address to access-list
! 482: name.
! 483:
! 484: ** When "bgp enforce-first-as" is enabled, check EBGP peer's update
! 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:

! 1075:
! 1076: * Changes in lib
! 1077:
! 1078: ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada
! 1079: <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address,

! 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

! 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

! 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

! 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

! 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

! 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]

! 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

! 1449: set ipv6 next-hop local fe80::cbb5:591a
! 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:
! 1488: * Changes in zebra-0.79
! 1489:
! 1490: * Changes in zebra
! 1491:
! 1492: ** Broadcast address setting on Linux box bug is fixed.
! 1493:
! 1494: ** Protocol daemon can install connected IPv6 route into the kernel.
! 1495:
! 1496: ** Now zebra can handle blackhole route.
! 1497:
! 1498: * Changes in ripd
! 1499:
! 1500: ** Add route-map feature for RIP protocol.
! 1501:
! 1502: ** In case of RIP version 2 routing table entry has IPv4 address and
! 1503: netmask pair which host part bit is on, ignore the entry.
! 1504:
! 1505: * Changes in ripngd
! 1506:
! 1507: ** Change CMSG_DATA cast from (u_char *) to (int *). (u_char *) does
! 1508: not work for NetBSD-currnet on SparcStation 10.
! 1509:
! 1510: * Changes in ospfd
! 1511:
! 1512: ** MaxAge LSA treatment is added.
! 1513:
! 1514: ** ABR/ASBR functionality is added.

! 1518: ** ABR behaviors IBM/Cisco/Shortcut is added.
! 1519:
! 1520: * Changes in ospf6d
! 1521:
