It appears to be intentional; there was some discussion a couple years =
back, and the current behavior is for virtual interfaces to not receive =
link-local addresses.

Since I prefer to have bridge0 as the "main" interface, I simply =
manually configured a link local address:

ipv6_enable=3D"YES"
ipv6_gateway_enable=3D"YES"
ipv6_network_interfaces=3D"bridge0 gif0"
ipv6_ifconfig_bridge0=3D"fe80::21c:c0ff:fe7d:8c50%bridge0"
ipv6_ifconfig_bridge0_alias0=3D"2001:470:1f0b:XXXX::1 prefixlen 64"
ipv6_ifconfig_gif0=3D"2001:470:1f0a:XXXX::2 2001:470:1f0a:XXXX::1 =
prefixlen 128"

$ cat /etc/rtadvd.conf=20
bridge0:\
	:addrs#1:addr=3D"2001:470:1f0b:XXXX::":raflags#64:

The IPv4 side of gif0 is brought up through a linkup script triggered by =
mpd when my DSL connection comes up; that also updates the endpoint =
address for the HE tunnel.

Oh, this is on -stable from Dec 4.

HTH,
