Abstract
Techniques are provided for hash-based routing table management in a distributed network switch. A frame having a source address and a destination address is received by a switch module having bridge elements and a routing table divided into slices of buckets, each slice having a respective property and including one or more buckets. If a routing entry for the source address is found in a first slice of a first set of buckets of the routing table responsive to a lookup request for the source address, and the property of the first slice satisfies a replication condition, then the routing entry is replicated to a second set of buckets of the routing table.
