Abstract: Various example embodiments for supporting egress rerouting of data packets in communication devices are presented herein. The egress rerouting of a data packet in a communication device may be performed by rerouting a data packet received via an ingress forwarding element of the communication device from a first egress forwarding element of the communication device associated with a primary next-hop for the data packet to a second egress forwarding element of the communication device associated with a secondary next-hop for the data packet.
