VLAN /Subnet bridging across a router

I have 2 Cisco 3550's (3550A & 3550B) seperated by a Cisco 2600. 3550A is connected to our Voice lab on VLAN54 in it's own subnet. I am trying to configure bridging on the 2600 to allow me to put ports on 3550B in VLAN54 and be in the same subnet as 3550A.

Is this possible?

Thanks,

yes, this is possible but why? It is better to segment both the voice vlan from data vlan. If they are both voice, they can still be segmented, it is better than bridging the 2600 interface. If you bridge both the interfaces that connects both 3500, then you will not be able to route their traffic unless you do IRB on the 2600.
