What u told is clear ..
i mean on a c3550 ; we can assign a L3 or a SVI to a bridge grp and we can
successfully bridge the IPV6 traffic.
What i mean to ask was that on 3560 .. which do not consider ipv6 as NON-IP
..
Like in the example given by narbik ; if we want ipv6 pings to also work
fine (along with legacy protocol) what shd we do
