I think you can bridge IPv6 in the 3550.

One additional note on the below, IPv6 doesn't get bridged either (but IPX
does).

It appears that fallback bridging on the 3550/3560 is for non-IP traffic
only. Is this correct?

Simple config:

no ip routing

bridge irb
bridge 1 protocol vlan-bridge
no bridge 1 route ip
bridge 1 bridge ip

int vlan 2
bridge-group 1

int vlan 3
bridge-group 1

IP hosts configured in the same subnet on VLAN 2 & VLAN 3 or router ports
assigned to bridge-group 1 still can't talk to each other. IPX works fine!
(I tried CRB as well, same result). It seems like all the documentation
states that this is really for bridging of non-IP traffic only, so I can
only assume that this is the case...

Thanks,
 Mike
