Abstract
Layer 2 services (such as Frame Relay, Asynchronous Transfer Mode, andEthernet) can be "emulated" over an MPLS backbone by encapsulatingthe Layer 2 Protocol Data Units (PDU) and transmitting them over"pseudowires". It is also possible to use pseudowires to providelow-rate Time Division Multiplexed and a Synchronous OpticalNETworking circuit emulation over an MPLS-enabled network. Thisdocument specifies a protocol for establishing and maintaining thepseudowires, using extensions to Label Distribution Protocol (LDP).Procedures for encapsulating Layer 2 PDUs are specified in a set ofcompanion documents.
