I am currently working for a client that has a primary MPLS WAN, but is requesting to have DSL redundancy in case of MPLS circuit failure. They are firm on this. I have one site currently up with redundancy via VPN tunnel over DSL...routing with BGP). Does anyone have other ideas (easier) for a solution?
I'm also running similar scenario where I have main lik is leased line and backup as DSL . I'm using GRE Tunel over DSL and configuring two BGP on the client side one thru Leased line and other thru GRE Tunnel (DSL) when primary link going down traffic will switch back thru DSL . I didn't see anyother solution for this
