Abstract
A method of forwarding a data packet includes, in part, receiving the data packet at an ingress interface, reordering entries of the data packet such that a first forwarding equivalence class (FEC), indexed by a first forwarding lookup table, is caused to point to a virtual private network (VPN) identifier associated with a tunnel through which the data packet is to be forwarded. The reordering of the entries causes a second FEC to point to a multitude of common tunnel header entries. The second FEC is indexed by the first FEC and has a lower level than the first FEC. The data packet with the reordered entries is forwarded through the tunnel. The egress tunnel header rewrite table entries are also reordered in accordance with which the data packet is forwarded.
