Abstract
A subset of route entries having the same next hop is identified in a route table. The subset of entries falls within a range of prefixes. Gaps in the subset of route entries that prevent the subset from being contiguous are identified. The gaps in the subset are filled with route entries to make the subset contiguous. All of the route entries in the contiguous subset of route entries have the same next hop, thus the contiguous subset can be aggregated into a single route entry in a forwarding table. For each gap-filling entry added to the route table, an additional route entry having forwarding priority over the gap-filling entry is added to the forwarding table.
