Abstract
A programmed network device and corresponding method are provided for rebuilding a multicast state upon experiencing a failure in a network using a protocol independent multicast (PIM) protocol. The method includes receiving updates to an outgoing list (Olist) for a given multicast route (mroute) at the network component and updating a PIM cache Olist in the network component with the received updates. During a state of recovering from the failure, the method includes determining whether the PIM cache Olist matches a centralized database Olist located in a centralized database. When a match is found, the method includes publishing an mroute state from the PIM cache to the centralized database.
