A New Internet-Draft is available from the on-line Internet-Drafts directories.
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 Provider-provisioned 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 ([VPN-VR]). This mechanism is based on the approach 
used by [RFC2547-bis] for distributing VPN routing information 
within the service provider(s). Each VPN scheme uses the mechanism 
to automatically discover the information needed by that particular 
scheme.

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.
