A method for processing network communications, the method including receiving a network packet at a network device and performing at least one lookup for the packet in one or more first lookup tables in which the one or more first lookup tables are programmed to include at least one of an exact match or longest prefix match (LPM) table entry. The method includes obtaining a security source segment and a security destination segment based upon the result of the at least one lookup for the packet in the one or more first lookup tables. The method further includes performing a lookup in a second lookup table based upon the security source segment and security destination segment in which the second lookup table is programmed in a content addressable memory. Based upon the result of the lookup in the second lookup table, processing a forwarding decision for the packet according to the security source segment and security destination segment.
