We have two locations, The customer is at location A and the Internet circuit is located at location B. All rfc1918 addresses will go out through the wan mpls and routed accordingly. However we need to get the Internet traffic from location A to location B and back without natively routing it across the mpls network.
So we have came up with a design using two routers at each location and deploying gre, We will use ospf and set the cost on one of them higher and let it perform failover incase a router dies. Is this the best solution or does anyone have a better idea?
See attached for diagram.
