Abstract
A method and apparatus for performing Layer 2 (L2) interworking is presented. A L2 Protocol Data Unit (PDU) is received at an L2 Switching Entity (SE). The L2 PDU is converted to a normalized Pseudowire (PW) PDU. The normalized PW PDU is then forwarded to a Layer 3 (L3) Routing Entity (RE). The normalized PDU may be in the form of a predetermined L2 protocol or a L2 agnostic protocol.
