Abstract
Techniques for intelligent designated forwarder (DF) and master router selection (for router redundancy) are provided. In one embodiment, a network router that is part of a set of network routers connected to a common LAN segment can retrieve a priority value adapted for use by the network router in electing a DF for multicast traffic. The network router can further check for the presence or absence of one or more routes to one or more multicast sources in a routing table of the network router. The network router can then modify the priority value based on the presence or the absence of the one or more routes and can transmit a multicast routing protocol control packet including the modified first priority value to one or more other network routers in the set of network routers.
