Abstract
A multicast destination table contains a list of links. The list of links includes the main link that is currently in use and alternate links to reach the same destination. The links in the list of links are ordered based on a metric. Each of the links is stored as an entry in the multicast destination table. A multicast replication engine traverses the list of links until an enabled link in the list of links is reached, and replicates a packet according to data associated with the enabled link in the list of links.
