Abstract:
In a network comprising a provider edge router coupled to each of a mated pair of core routers in a core network, a system and methodology for rerouting upstream traffic destined for the provider edge router in the event of a link failure between one of the core routers and the provider edge router. By detecting a link failure between a first of the mated pair of core routers and the provider edge router, and directing the upstream traffic destined for the provider edge router to a second of the mated pair of core routers, internal gateway protocol (IGP) reconvergence events are not triggered.
