Abstract
In one embodiment, a method includes performing, by a router, a destination address lookup of an IP packet in a Forwarding Information Base (FIB) and identifying, by the router, an equal cost multi-path (ECMP) object from the destination address lookup. The ECMP object includes a plurality of paths for forwarding the IP packet to a destination associated with a destination address. The method further includes determining, by the router, a source interface associated with the IP packet, determining, by the router, that the source interface matches an egress interface associated with a path among the plurality of paths, and communicating, by the router, the IP packet based on the path to the destination using the egress interface.
