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="YES" ipv6_gateway_enable="YES" ipv6_network_interfaces="bridge0 gif0" ipv6_ifconfig_bridge0="fe80::21c:c0ff:fe7d:8c50%bridge0" ipv6_ifconfig_bridge0_alias0="2001:470:1f0b:XXXX::1 prefixlen 64" ipv6_ifconfig_gif0="2001:470:1f0a:XXXX::2 2001:470:1f0a:XXXX::1 prefixlen 128" $ cat /etc/rtadvd.conf bridge0:\ :addrs#1:addr="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, Stefan -- Stefan Bethke <stb@lassitu.de> Fon +49 151 14070811
