Systems and methods for automatically detecting routing peers

Abstract:

Methods and systems are described for automatically detecting network routing peers and establishing route peering sessions. An illustrative method includes retrieving, at a network router, route peer configuration for the network router. The route peer configuration identifies one or more network interfaces for route peering but typically does not identify an address of peer routers. The method identifies, based on the route peer configuration, a network interface from a plurality of network interfaces of the network router for route peering and configures the network interface to participate in route peering. The method then detects a peer router on the network interface and initiates a peering session on the network interface with the peer router. Using the peering session, the method exchange route information with the peer router.
