Hi, I seem to have run into a brick wall and would appreciate any solution you can come up.

My client basically has two sites. Both sites have their own router and L3 switch. The routers are linked using multiple E1's bundled with MLPPP. Both L3 switches have multiple VLANs and are routed between sites using EIGRP.

Now this is where the fun stops. For some reason, the client needs to bridge a certain VLAN across the two sites in favor of running a relatively old application. This application, it seems, needs broadcast and other non-routable traffic to function on both sites. Furthermore, this bridged VLAN must still be able to see the other networks from both sites (ie. all L3 VLANs).

I have configured IRB before on a single box, but not across multiple L3 devices.

Any help on pointing me to the right direction is welcome.
