  • Rendezvous point link resiliency for bidirectional protocol independent multicast (PIM-BIDIR)
    Patent number: 9602294
    Abstract: Techniques provide rendezvous point link (RPL) resiliency for bidirectional protocol independent multicast (PIM-BIDIR) in a computer network. According to the techniques, when two or more RPL partitions have a same RPL subnet, routers on the RPL subnet are configured to elect an active RPL partition that will function as a RPL. The routers on any inactive RPL partitions may then treat the inactive RPL partitions as regular links in the RPL subnet and build a route to the active RPL partition. In some examples, the network is configured to include the two or more RPL partitions with the same RPL subnet as Anycast RPLs in the network. In other examples, the routers on the RPL subnet are configured to detect when an original RPL is separated into the two or more RPL partitions due to a failure of the original RPL.
