Abstract
A system and method of extending a standard bridge to enable execution of logical bridging functionality are disclosed. In some implementations, a logical bridge may assign source logical port information to a data packet based on characteristics of the data packet, employ the source logical port information to learn the source address and to forward the data packet to a logical egress port, and map the logical egress port to a physical egress port at which the data packet is to be egressed. A tunnel interface may optionally be applied to a data packet upon egress.
