Assuming the gif has outer IP addresses and inner IPv6 addresses (link
local for ripng, real for bgp), it is highly unlikely to be appropriate
to run rtadvd on it.   Is the gif for you to get connectivity, or to
provide it?

If the three local ethernet interfaces are bridged, then presumably they
are one logical network and I'd pick one to run rtadvd on, by the same
logic that you'd pick one of them for dhcpd.
