Techniques for operating a network device for sharing resources in a hardware forwarding table. In some embodiments, the network device may generate groups of routes having a common set of next hops; for each group of routes of the generated groups: collect resilient adjacencies associated with routes in the group; assemble pairs of the collected resilient adjacencies; and determine a number of differences between resilient adjacencies in each of the assembled pairs. The network device may further order the assembled pairs based on the number of differences, identify a pair of resilient adjacencies associated with a lowest number of differences; select a resilient adjacency of the identified pair of resilient adjacencies; program one or more routes associated with the selected resilient adjacency, to refer to the other resilient adjacency of the identified pair of resilient adjacencies; and remove an entry associated with the selected resilient adjacency from a forwarding table.
