Provider Provisioned Layer 2 Virtual Private Networks (L2VPNs) may
have different "provisioning models", i.e., models for what
information needs to be configured in what entities.  Once
configured, the provisioning information is distributed by a
"discovery process".  When the discovery process is complete, a
signaling protocol is automatically invoked to set up the mesh of
pseudowires (PWs) that form the (virtual) backbone of the L2VPN.
This document specifies a number of L2VPN provisioning models, and
further specifies the semantic structure of the endpoint identifiers
required by each model.  It discusses the distribution of these
identifiers by the discovery process, especially when discovery is
based on the Border Gateway Protocol (BGP).  It then specifies how
the endpoint identifiers are carried in the two signaling protocols
that are used to set up PWs, the Label Distribution Protocol (LDP),
and the Layer 2 Tunneling Protocol version 3 (L2TPv3).  [STANDARDS-
