I want to extend a vlan across a mutihop ip network. what are my options apart from L2TPv3 as the vlans will be extended from 6509 (12.2(33)SXI) to 4507(12.2(50)SG). 4507 doesnt support it and 6509 doesnt have any other encapsulation type other than MPLS and my network is not mpls enable.
I m thinking of transparent bridging over GRE tunnel ... will it work ?
any other options if any available..
