Hi Modular
Sorry I couldnt get the question completely ..
can u paste come configs indicating the problem ..
also i guess u are aware that in 3550 -> IPv6 can be bridged using fallback
bridging .
so if u are routing ipv6 ; via 3550 this will work on 3560 and not 3550 .
On 3550 ; the solution is to vlan bridge the stuff ( bridge 10 protocol
vlan-bridge)
HTH
