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.

Abstract: A first network device is configured with a rule preventing network traffic from travelling from the first network device to one or more other network devices. The first network device is configured to receive and distribute network traffic to the one or more other network devices. A second network device receives and distributes network traffic to the one or more other network devices. The first network device determines that the second network device has failed. In response to determining that the second network device has failed, the first network device removes the rule so that the first network device receives and distributes network traffic to the one or more other network devices.

Abstract: The present disclosure describes using Address Resolution Protocol (ARP) to determine whether a host is behind a PE or not behind a PE. In a use case, for example, advertising a Selective Provider Multicast Service Interface Auto-Discovery (S-PMSI-AD) route to advertise encapsulation of a multicast group is triggered by receiving multicast traffic for that group from a host device behind the provider edge (PE) device. Multicast traffic received from behind remote PEs will not trigger a S-PMSI-AD route.
