  • Ingress gateway selection for a shortest path bridging network to support inter domain multicast routing
    Patent number: 10680931
    Abstract: In a Shortest Path Bridge (SPB) network comprising a plurality of backbone edge bridges (BEBs), a gateway controller of the SPB network, establishes a link using Multicast Source Discovery Protocol (MSDP) with an external network domain; discovers via the link a source of a multicast stream originating outside of the SPB network; and determines a subset of the plurality of BEBs that are able to receive the multicast stream from the source. Once that occurs, the gateway controller selects a one of the subset of the plurality of BEBs to be a sole gateway BEB for the multicast stream; and then transmits to each of the subset of the plurality of BEBs an indication of the sole gateway BEB selected for the multicast stream.

  • Layer 3 (L3) best route selection rule for shortest path bridging multicast (SPBM) networks
    Patent number: 9806989
    Abstract: A method, apparatus and computer program product for providing a best route selection rule is presented. A determination is made at a first edge router, whether a second edge router in a network advertises a first BMAC address and at least one other BMAC address When the second edge router advertises only a first BMAC address, then the first BMAC address is used in a routing table for a Layer 3 (L3) next hop for a route. When the second edge router advertises more than one BMAC address, at least one other BMAC address is used in the routing table for said L3 next hop for the route.
