  • Methods and apparatus for multicast traffic failover in a network
    Patent number: 9485198
    Abstract: An apparatus includes an access switch having a set of ports and configured to be operatively coupled to a multicast router via a first port from the set of ports. The access switch is configured to be associated with a network associated with the multicast router, and designate the first port as a multicast-router interface during a time period. The access switch is configured to send a message to the multicast router via each port from the set of ports in response to an indication of a change in a topology of the network after the time period. The access switch is configured to designate a second port from the set of ports as the multicast-router interface and dedesignate the first port as the multicast-router interface in response to receiving, via the second port and in response to the message, a signal from the multicast router.
