According to certain embodiments, a router comprises one or more processors and one or more computer-readable non-transitory storage media. The one or more computer-readable non-transitory storage media comprise instructions that, when executed by the one or more processors, cause one or more components of the router to perform operations comprising determining an occurrence of one or more network events associated with a multicast service, generating route exchange information associated with the multicast service locally by the router based on the one or more network events, and using the route exchange information locally to configure the router.

Optimized MVPN route exchange in SD-WAN environments

According to certain embodiments, a method by a router in a software-defined wide-area network (SDWAN) includes determining one or more replicators in the SDWAN and generating a multicast distribution tree that includes the determined one or more replicators. The method further includes receiving multicast traffic from a source and creating a (S,G) route for the received multicast traffic. The method further includes replicating the multicast traffic using the multicast distribution tree.

Systems and methods for providing SDWAN IP multicast without a rendezvous point

According to certain embodiments, a system comprises one or more processors and one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations. The operations comprise selecting a primary node to replicate multicast traffic and forward the multicast traffic to a plurality of receivers, selecting one or more secondary nodes to provide node-level redundancy for the primary node, and providing the one or more secondary nodes with synchronization information that enables the one or more secondary nodes to replicate the multicast traffic and forward the multicast traffic to the plurality of receivers in response to the primary node becoming unavailable. Selecting the primary node is based in software.
