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.
