Abstract
The subject matter described herein includes methods, systems, and computer program products for source-aware IP routing at a media gateway. According to one aspect, a method for source-aware IP routing at a media gateway is provided. The method includes providing a packet including a layer 3 source address and a layer 3 destination address at a media gateway having a source-aware routing table. Using the destination address included in the packet, at least one entry corresponding to the destination address is located in the source-aware routing table, where the located entry contains at least a portion of a source IP address, at least a portion of a destination IP address and routing information including an interface identifier and a next hop identifier. From among the at least one located entry corresponding to the destination IP address information, at least one entry corresponding to the source IP address included in the packet is located. Based on the routing information located in the routing table, the packet is routed to the destination.
