Abstract
A network device selects a primary source for multicast traffic and a secondary source for the multicast traffic, where the multicast traffic is provided to endpoint devices communicating with a network, and where the primary source and the secondary source are redundant sources. The network device provides a first join request that includes information that causes a primary path to be provided from the primary source through the network. The network device provides a second join request that includes information that causes a secondary path to be provided from the secondary source through the network. The network device receives the multicast traffic from the primary source via the primary path and the secondary source via the secondary path, and provides the multicast traffic received from the primary source to the endpoint devices. The network device prevents the multicast traffic received from the secondary source from reaching the endpoint devices.
