Abstract
Exemplary methods performed by a first network device (ND) include generating first and second prefix entries associating incoming Internet Protocol (IP) traffic to first and second data structures (DSs), respectively. Generating the first DS includes generating a first proxy including forwarding information causing incoming IP traffic to be forwarded to a second ND, and generating a second proxy referencing a third DS. Generating the second DS includes generating a first proxy including forwarding information causing incoming IP traffic to be forwarded to the second ND, and generating a second proxy referencing the third DS. The methods include generating the third DS including forwarding information causing the incoming IP traffic to be forwarded to a third ND, the third DS further including first state information indicating whether the forwarding information included in the first proxies of the first and second DSs should be used for forwarding the incoming IP traffic.
