There are a number of different kinds of "Provider Provisioned Layer 2
VPNs" (L2VPNs). The different kinds of L2VPN may have different
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. The
signaling protocol sets up the mesh of Pseudowires (PWs) that form the
(virtual) backbone of the L2VPN. Any PW signaling protocol needs to have a
method which allows each PW endpoint to identify the other; thus a PW
signaling protocol will have the notion of an endpoint identifier. The
semantics of the endpoint identifiers which the signaling protocol uses for
a particular type of L2VPN are determined by the provisioning model. This
document specifies a number of L2VPN provisioning models, and further
specifies the semantic structure of the endpoint identifiers required by
each provisioning model. It discusses the way in which the endpoint
identifiers are distributed by the discovery process, especially when the
discovery process is based upon 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 (L2TPv3).
