A packet classifier and a method for routing a data packet are provided. The packet classifier includes a content addressable memory, a translation table and a parameter memory. The method includes looking up a content addressable memory for a base address into a parameter memory using a header of the data packet. The base address is related to the routes under ECMP for forwarding the data packet. From among these addresses, using multiple headers of the data packet, an adjustment to the base address is computed. The adjustment specifies an actual address to the parameter memory corresponding to a selected route for forwarding the data packet. The parameter memory is then accessed using the actual address to obtain parameter values relevant to the selected route. The data packet is then forwarded according to the parameter values thus obtained.
