Abstract

Peer devices in a peer group of provider edge devices to which a customer edge device is multi-homed, advertise Selective Multicast Ethernet Tag (SMET) routes to other peer devices on a core to receive traffic addressed to a multicast group. The peer devices in the peer group advertise the SMET routes irrespective of whether they are the designated forwarder or not. A peer device receiving traffic for the multicast group will drop the packet if it is not the designated forwarder and will forward the packet if it is the designated forwarder.
