A method and apparatus of a network element that processes network data in an equal cost multi-path (ECMP) group is described. In an exemplary embodiment, the network element receives the network data, where the network data is part of network data flow. In addition, the network element detects that the network data flow is a new network data flow and selects a transmitting nexthop from a plurality of nexthops of the ECMP group. The network element further maps the new network flow to a slot of a table in an ECMP group and transmits the network data using the transmitting nexthop.

Various systems and methods for implementing efficient TCAM resource sharing are described herein. Entries are allocated across a plurality of ternary content addressable memories (TCAMs), with the plurality of TCAMs including a primary TCAM and a secondary TCAM, where the entries are allocated by sequentially accessing a plurality of groups of value-mask-result (VMR) entries, with each group having at least one VMR entry associated with the group, and iteratively analyzing the VMR entries associated with each group to determine a result set of VMR entries, with the result set being a subset of VMR entries from the plurality of groups of VMR entries, and the result set to be stored in the primary TCAM.
