Abstract
In general, techniques are described for enabling a network of network devices (or “nodes”) to provide redundant multicast streams from redundant multicast sources to an egress network node. In some examples, the egress network node (or a controller for the network) computes maximally redundant trees (MRTs) from the egress network node to a virtual proxy node virtually added to the network topology by the egress network node for redundant multicast sources of redundant multicast streams.
