This draft is a work item of the Layer 3 Virtual Private Networks Working Group of the IETF.
Title : Using BGP as an Auto-Discovery Mechanism for Layer-3 and
Layer-2 VPNs

In any Provider Provisioned-Based VPN (PPVPN) scheme, the Provider
Edge (PE) devices attached to a common VPN must exchange certain
information as a prerequisite to establish VPN-specific
connectivity. The purpose of this draft is to define a BGP based
auto-discovery mechanism for both layer-2 VPN architectures and
layer-3 VPNs (Virtual Routers ûVR [VPN-VR]). This mechanism is based
on the approach used by BGP/MPLS-IP-VPN [BGP/MPLS-IP-VPN] for
distributing VPN routing information within the service provider(s).

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
Internet-Draft.
