Abstract:

Provided herein are systems and methods for managing redistribution and remapping of multicast services between networks in a multi-area network. Multicast streams can be sent through networks from a source node towards a boundary node. The boundary node can receive the multicast stream, remap a source node identifier and service instance identifier, and forward the multicast stream into a second network. The boundary node can receive a route for the multicast stream. The route can be installed in a link-state database and can be used to send the multicast stream through the multi-area network from the source node to a destination node.

Abstract:

Provided herein are systems and methods for providing a MAC-based redistribution policy between networks in a multi-area network. A network can have a boundary node that communicates to neighboring networks. Boundary nodes can receive policy updates that identify which services are redistributable across network boundaries. Boundary nodes can receive a packet for a service, translate the packet's encapsulation, and forward the packet across the boundary towards a destination node. Boundary nodes can forward the packet such that it originates in the second network from a virtual node.
