Title : Provisioning Models and Endpoint Identifiers in L2VPN Signaling
Author(s) : E. Rosen, V. Radoaca
Filename : draft-ietf-l2vpn-signaling-01.txt
Pages : 24
Date : 2004-3-11
[PWE3-CONTROL] specifies a 'signaling protocol' which uses extensions
of LDP [RFC 3036] to set up and maintain pseudowires [PWE3-ARCH].
Like any protocol which sets up connections, the signaling protocol
provides a method by which each endpoint can identify the other.
[L2VPN-FW] describes a number of different ways in which sets of
pseudowires may be combined together into 'Provider Provisioned Layer
2 VPNs' (L2 PPVPNs, or L2VPNs), resulting in a number of different
kinds of L2VPN. Different kinds of L2VPN may have different
'provisioning models', i.e., different models for what information
needs to be configured in what entities. Once configured, the
provisioning information is distributed by a 'discovery process', and
once the information is discovered, the signaling protocol is
automatically invoked to set up the required pseudowires. 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 PPVPN
provisioning models, and specifies the semantic structure of the
endpoint identifiers required. It further specifies how the endpoint
identifiers are carried in the 'Generalized Identifier FEC' of
[PWE3-CONTROL]. It is believed that the specified identifiers can
also be carried within the L2TP signaling protocol, though this is
currently not specified.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
