A system and method automatically maps network addresses of a first protocol for a plurality of network elements in a first network to network addresses of a second protocol. A table is defined and maintained in each network element of the plurality of network elements. An identifier within the first protocol for each network element of the plurality of network elements and an address corresponding to the second protocol-for each network element of the plurality of network elements is assigned and stored in the table. The first protocol identifier is associated with the address corresponding to the second protocol within the table for each network element of the plurality of network elements.
