Abstract:
1. A method, comprising: determining, by a particular provider edge (PE) device of a plurality of multi-homing PE devices between a core network and a local network, a subset of traffic for which the particular PE device is responsible; establishing, by the particular PE device with itself as root, a multicast tree within the local network for one or more underlay multicast groups; admitting traffic received at the particular PE device from the core network into the local network only if the core traffic corresponds to the subset of traffic for which the particular PE device is responsible, the admitted traffic mapped by the particular PE device into one of the one or more underlay multicast groups for which the particular PE device is the root; and forwarding multicast traffic received at the particular PE device from the local network into the core network only if the multicast traffic corresponds to the subset of traffic for which the particular PE device is responsible, wherein the core traffic received at the particular PE device from the core network into the local network is received at the particular PE from a label switched multicast (LSM) tree.
