  • Patent number: 9088498
    Abstract: A method of operating a communication network comprises receiving loopback addresses from a plurality of edge networks at a provider router of a core backbone network, the edge networks and the core backbone network being logically distinct from each other, advertising the loopback addresses to a transport route reflector element, propagating the advertisement of the loopback addresses to other provider routers of the core backbone network using a protocol for communicating between autonomous systems, and using the transport route reflector element to advertise at least one of the loopback addresses to a service route reflector element in one of the plurality of edge networks.
    Type: Grant

    Date of Patent: July 21, 2015

  • Patent number: 7894462
    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.
