So- use pseudowire or another encapsulation (l2vpn) technique.

No agencies. yes, exactly thats the case; i have both offices linked using encrypted gre tunneling (vti interface) and need to access on vlan on office 1 from office 2. I need to make something like, lets say a subinterface on the tunel that connects both switches and vlan. Im not sure if i explain the idea correctly :-) thanks |
