Abstract
Methods, systems, and computer program products for controlling updating of a layer 3 host table based on packet forwarding miss counts are disclosed. According to one method, layer 3 packets are routed using at least one of a layer 3 host table containing entries corresponding to remote hosts and a longest prefix matching table containing prefixes corresponding to remote hosts. For each layer 3 destination address for which a lookup in at least one table fails, a number of packets received within a time period are counted. Remote destination entries in the host table are replaced based on the counts.
