I need to setup a bridge (non-routing) for a single network over a T1 line.  Routers will be two cisco 1720s.

Please post exact config for bridging configuration.  

Can the routers still be assigned an IP on the ethernet interface and do bridging?

Thanks!

Yes, you can have an IP address assigned and bridge, but the interface is a Bridged Virtual Interface

bridge 1 protocol ieee
router irb
interface Serial 0
  no ip address
  bridge-group 1
interface fastethernet 0
 no ip address
 bridge-group 1
interface BVI1
  ip address 192.168.168.100 255.255.255.0
ip route 0.0.0.0 0.0.0.0 192.168.168.1

Same config on both sides, different IP on the BVI

Thanks!   So router nbr 2 would have the idential configuration, except the ip address would be different (but still in the same network) ??

Thanks,

Can you ping the gateway from the router console?
