Patent ID: 10999195

Abstract:
Techniques are disclosed for seamless integration between a multicasting Virtual Private Network and an edge replicated multicast network. For example, a controller (e.g., software defined networking (SDN) controller) may facilitate the integration between a multicasting VPN network and an edge replicated multicast network through the selection of a multicast bridge node from virtual routers specified in the multicast replication tree, and sending information identifying the multicast bridge node to a provider edge (PE) device for the source VPN such that the PE device may use the information to steer multicast traffic from the source VPN site across the Layer 3 VPN network to the multicast bridge node of the receiver VPN site. When the multicast bridge node receives the multicast traffic, the multicast bridge node determines from the information that it is to receive the multicast traffic and to perform the edge replicated multicast using the edge replicated multicast tree.
