Abstract
A method and system for forwarding traffic from a plurality of logical networks using a single forwarding table. Traffic is received in the form of packets with a key and a logical traffic identifier. The routing table is traversed to a forwarding table entry having a longest prefixed search value that matches the key and having a logical network identification array in which the logical traffic identifier may be represented. If the logical traffic identifier is represented in the logical network identification array, then the packet is forwarded in accordance with forwarding information associated with the forwarding table entry.
