ABSTRACT:
The invention is directed to methods, apparatus and systems for processing a data packet that has a destination address. In the event that in a routing table cache and in a routing table, there is no entry with a destination address prefix that is a prefix of the destination address, a default-route-prefix is determined in a default-route determination step.
