what is the best solution to extend a node (PE router) over a third party IP network.
Here is the scenario - there is a need to extend an MPLS network to a new location, but due to commercial/policy reason the only available options are a third part IP Network (non-MPLS) and a back haul wireless link. We are thinking of making the IP Network the primary link and the wireless back haul the back up links.
Is L2TPv3 the only solution? I want to make use of the wireless back haul also for some traffic.
