Abstract:

This disclosure describes techniques for improving convergence of Protocol Independent Multicast assert state information in multicast groups. A method includes forwarding, by a router, a PIM join message originating from a destination host and stores distribution tree information based on the join message. The method further includes participating, by the router, in a Protocol Independent Multicast (“PIM”) assert election among a plurality of routers and storing, by the router, PIM assert state information based on an outcome of the PIM assert election. The method further includes acquiring, by the router, routing information base (“RIB”) convergence. The method further includes triggering by the router, or causing, by the router, another router to trigger, a PIM assert among the plurality of routers. The method further includes re-converging, by the router, with PIM assert states among the plurality of routers and storing, by the router, converged PIM assert state information.
