    Abstract: A network device may identify first interfaces used by the network device to communicate with other network devices. The network device may use second interfaces to communicate with multicast receiver devices that are different from the other network devices. The network device may store information that identifies the first interfaces used to communicate with the other network devices. The network device may receive a packet, and may determine that the packet includes a bidirectional forwarding detection message, associated with a bidirectional forwarding detection protocol, to be used to verify multicast connectivity with a multicast source device. The network device may identify the first interfaces based on the stored information and based on determining that the packet includes the bidirectional forwarding detection message, and may transmit the packet via the first interfaces without transmitting the packet via the second interfaces.

    Abstract: In one example, a first routing device of an Ethernet virtual private network (EVPN) is multihomed to a customer edge (CE) routing device with a second routing device. The first routing device includes one or more network interfaces configured to send and receive packets. The first routing device also includes one or more processors configured to receive, via the one or more network interfaces, a first packet from the CE routing device including multicast join information, update multicast state information of the first routing device using the multicast join information from the first packet, and send, via the one or more network interfaces, a second packet including data representative of the multicast join information to the second routing device to synchronize multicast state information of the second routing device with the multicast state information of the first routing device.
