Zusammenfassung: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. If no routing entry for the source address is found in a routing table of a switch module in the distributed network switch, where the routing table is divided into slices of buckets, 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 and based on a set of hash functions and properties of the slices.
