Guarav -

On C3560 FB is (in my opinion) not of place. You can use it to isolate
and contain or demarcate legacy protocols and equipment to certain VLANs.

And the SW doesn't need to speak these protocols itself.

I hope I understood your q

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
