Hi,
I am trying to get a -CURRENT box to get an IPv6 address via RTADV, =
however I am not having any luck.

I have tried the following in rc.conf :-
ipv6_enable=3D"YES"
ipv6_gateway_enable=3D"YES"

ifconfig_em0_ipv6=3D"RTADV"

(the last one I haven't seen before but it didn't seem to have an effect =
anyway)

ifconfig shows..
em0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu =
1500
	=
options=3D219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_=
MAGIC>
	ether 00:25:90:32:09:1e
	inet6 fe80::225:90ff:fe32:91e%em0 prefixlen 64 scopeid 0x2=20
	inet 203.31.81.43 netmask 0xffffffc0 broadcast 203.31.81.63
	nd6 options=3D21<PERFORMNUD,AUTO_LINKLOCAL>
	media: Ethernet autoselect (100baseTX <full-duplex>)
	status: active

I see rtadv packets on the network :-
12:50:46.444380 IP6 fe80::204:61ff:fe79:276f > ff02::1: ICMP6, router =
advertisement, length 56

Other hosts can obtain a prefix just fine. This is the only 9.0 one, I =
have other FreeBSD boxes but they are 8.x ish.
