Abstract
A backbone network may include first and second border routers and a route reflector. The first border router may provide data connectivity between the backbone network and a first regional network. The first border router may be configured to receive a notification of a change in status of an edge router of the first regional network, and the notification may be received according to a first routing protocol. The first border router may be further configured to redistribute the notification of the change in status of the edge router from the first routing protocol to a second routing protocol with the first and second routing protocols being different. The second border router may provide data connectivity between the backbone network and a second regional network. The route reflector may be coupled between the first and second border routers, and the route reflector may be configured to transfer the redistributed notification from the first border router to the second border router. Related routers, methods, and computer program products are also discussed.
