The tunnel is configured like this: buffoon# ifconfig gif0 gif0: flags=8011 mtu 1280 inet6 fe80::2d0:b7ff:fe79:a0a7%gif0 --> :: prefixlen 64 scopeid 0x4 inet6 2001:438:1fff:ffff:8::32 --> 2001:438:1fff:ffff:8::31 prefixlen 126 v6-core6.iad1#sh run int tun7 Building configuration... Current configuration : 252 bytes ! interface Tunnel7 description v6-in-v4 tunnel to buffoon-gif0.automagic.org bandwidth 10000 no ip address ipv6 enable ipv6 address 2001:438:1FFF:FFFF:8::31/126 tunnel source Loopback0 tunnel destination 208.185.30.208 tunnel mode ipv6ip end Functionally, everything is working marvelously. However, the kernel is spitting out screeds of these: nd6_lookup: failed to add route for a neighbor(2001:0438:1fff:ffff:0008::0031), errno=17 Lots and lots of them :) Sep 10 11:14:02 buffoon /kernel: nd6_lookup: failed to add route for a neighbor(2001:0438:1fff:ffff:0008::0031), errno=17 Sep 10 11:14:02 buffoon last message repeated 14 times Sep 10 11:16:02 buffoon last message repeated 116 times Sep 10 11:23:03 buffoon last message repeated 73 times Sep 10 11:35:33 buffoon last message repeated 109 times Sep 10 11:46:03 buffoon last message repeated 344 times Sep 10 11:56:03 buffoon last message repeated 1302 times Sep 10 11:57:55 buffoon last message repeated 113 times I can ping ....:31 just fine from buffoon. It seems like I either need to turn something off on the FreeBSD box, or on on the cisco. I don't know anything much about icmp6 neighbour discovery, though, so I'm not sure exactly what. Does anybody happen to know a good way of suppressing these log messages? I'd appreciate a cc on reply, since I'm not subscribed to -net.
