>Description:
If i have a bridge interface where ip6 autoconfiguration doesn't work on this. My ifconfig looks like this:
bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 172.29.30.3 netmask 0xffffff00 broadcast 172.29.30.255
ether e2:e4:1a:9e:ef:b7
priority 32768 hellotime 2 fwddelay 15 maxage 20
member: vlan30 flags=3<LEARNING,DISCOVER>
vlan30: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::213:8fff:fee7:15f7%vlan30 prefixlen 64 scopeid 0x16
ether 00:1b:21:05:02:66
media: Ethernet autoselect (1000baseTX <full-duplex>)
status: active
vlan: 30 parent interface: em0
And tcpdump give me this but there is no configuration reflected as you see:
1199651104.651136 f2:56:04:43:00:3e > 33:33:00:00:00:01, ethertype IPv6 (0x86dd), length 110: XXXX:XXX:XXX:30::1 > ff02::1: ICMP6, router advertisement, length 56
BTW this is not a general problem on the same box a other vlan interface works fine (without a bridge):
vlan251: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::213:8fff:fee7:15f7%vlan251 prefixlen 64 scopeid 0xe
inet 172.16.251.2 netmask 0xffffff00 broadcast 172.16.251.255
inet 172.16.251.11 netmask 0xffffffff broadcast 172.16.251.11
inet 172.16.251.10 netmask 0xffffffff broadcast 172.16.251.10
inet6 2001:6f8:966:252:213:8fff:fee7:15f7 prefixlen 64 autoconf
ether 00:1b:21:05:02:66
media: Ethernet autoselect (1000baseTX <full-duplex>)
status: active
vlan: 251 parent interface: em0
i have no real clue where to look in the kernel-source but if somebody has a idea why the packet looks like dropped, i will investigate by my self-:)
thanks in advance
