Abstract

In some examples, a method includes receiving, by a first ingress network device for a network, a source tree join route message from an egress network device for the network, specifying a multicast source and a multicast group, and in response to receiving the source tree join route message, determining, by the ingress network device, whether the multicast source is multi-homed to the network via the first ingress network device and a second ingress network device for the network. The method includes, in response to determining that the multicast source is not multi-homed, forwarding traffic for the multicast source on an inclusive provider tunnel without initiating setup of a selective provider tunnel to the egress network device, and in response to determining that the multicast source is multi-homed, initiating setup of a selective provider tunnel to the egress network device and terminating forwarding multicast traffic on the inclusive provider tunnel.
