Abstract
Techniques are provided for cached routing table management in a distributed network switch. A frame having a source address and a destination address is received. If no routing entry for the source address is found in a routing table of a switch module in the distributed network switch, then routing information is determined for the source address and a routing entry is generated. The routing table is modified to include the routing entry, based on a set of hash functions. Upon accessing the generated routing entry in the modified routing table responsive to a subsequent lookup request for the source address, the set of caches is modified to include the generated routing entry.
