Dynamic forward information base prefix optimization

Abstract:

A network device includes a routing information base including a first plurality of entries, a forwarding information base including a second plurality of entries; a forwarding information base entry optimizer that programs the second plurality of entries of the forwarding information base using, at least in part, the first plurality of entries; and a network processor that forwards packets based on the second plurality of entries of the forwarding information base. The second plurality of entries is less than the first plurality of entries.
