Abstract

A method, apparatus and article of manufacture for aggregating a sorted list of IP prefix pairs. A prefix pair in the list is compared to a lowest IP length subnet boundary. The prefix pair is added to a final list if the prefix pair is not on the lowest IP length subnet boundary and the prefix pair is not a first in pair. The prefix pair is moved to a next lower length list if the prefix pair is on the lowest IP length subnet boundary and the prefix pair is a next expected pair. A next higher list is selected, and the method is repeated until there are no more lists.
