GRE tunnel Setup ( Bridging Interfaces )

Joe Mullis

Level 1

I have two Cisco 2941's going over a IPSEC VPN. I need to push the same network over this connection. For example i need 192.168.255.0 / 25 on my side and i need to plug in a laptop on the far end 2941 with the same network.  I have built GRE tunnels before and i found a configuration online to brdige interfaces over a GRE tunnel.

when i get to adding the bridging to the configuration which i will show below i get an error. Please see below. Also when i try to add the same briding command on the GRE tunnel which is needed it doesnt show the bridging command as being available. The Cisco 2941's are both using version: mwr2941-iprank9-mz.124-20.MRb1.bin.

interface gig0/4

..........

bridge-group 1                  

^^^ when i try to run this command i get the error:

Gigabitethernet0/3 does not support bridging.

Please help. As i stated the only end result i need is to be able to configure a path from point A and B and have the same network on each end.

i should state the VPN is not done on the 2941 it is done with a ASA5520 and 5510.
