    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.

    Abstract: In one embodiment, a method includes generating at a network device, a trace packet comprising an IP (Internet Protocol) to Source Group Tag (SGT) binding, transmitting the trace packet from the network device to an SGT capable device, wherein at least one non-SGT capable device is interposed in a path between the network device and the SGT capable device, and receiving at the network device, a reply packet from the SGT capable device in response to the trace packet, the reply packet indicating that the IP to SGT binding was installed at the SGT capable device. An apparatus and logic are also disclosed herein.
