Abstract
Some embodiments provide a method for a forwarding element that forwards packets. The method receives a packet and consults a tree structure to identity a prefix length associated with an IP address in the packet header. The method skips lookup of each subtable with a set of IP addresses that have a different prefix length than the identified prefix length. The method identifies a matching rule from a particular subtable. The method generates a flow based on the matching rule. The flow is used to process packets that have the same prefix.
