Abstract
A node, in a first network, includes circuitry configured to determine a next hop as decided by Border Gateway Protocol (BGP) is an anycast prefix to a Route Reflector (RR) interconnecting the first network with a second network, responsive to the next hop being the anycast prefix to the RR, create a tunnel with a destination based on the anycast prefix, and utilize the tunnel for traffic having the next hop as the anycast prefix to the RR. The anycast prefix is assigned to two or more RRs interconnecting the first network and the second network. A first path is decided by BGP based on a BGP Path Selection Algorithm that is independent of a second path determined by Interior Gateway Protocol (IGP). The first path and the second path can be different, and wherein tunnel is utilized to ensure the traffic always follows the first path.
