I had a very similar situation but the whole thing fell apart because in
order for you to link the bridging interfaces with routing you need a BVI.
Also you need to link the tunnel to the interface that you wish to
bridge....the routers that I tried it on would not accept a tunnel being
part of a bridge group. I then did accomplish it by using DLSW+ with some
limited success. I am very curious if some one did make it work with the
tunnels, since that I what I wanted to do in the very beginning.

Subject: GRE Tunneling & Bridging
Is it possible to connect 2 locations via the Internet and have both
locations share the same subnet ?
I know that this is theoretically possible by using a GRE Tunnel between the
2 routers at each location AND by
activating IRB on the routers.
(Each router will have a minimum of 3 interfaces - subnet, dmz, & Tunnel;
subnet & dmz interfaces
will route IP - subnet & Tunnel will bridge IP).
Can this work in the real world and has anybody done this before ?
The reason the 2 locations need have the same subnet is that Unix Hosts at
each location need to be configured
in a cluster group on the same subnet for disaster recovery purposes.
Thanks,
