Title : BGP-based Auto-Discovery for Layer-1 VPNs
Author(s) : H. Ould-Brahim
Filename : draft-ietf-l1vpn-bgp-auto-discovery-04.txt
Pages : 9
Date : 2008-2-8
The purpose of this document is to define a BGP-based auto-discovery
mechanism for Layer-1 VPNs (L1VPNs). The auto-discovery mechanism for
L1VPNs allows the provider network devices to dynamically discover
the set of PEs having ports attached to CE members of the same VPN.
That information is necessary for completing the signaling phase of
L1VPN connections. One main objective of a L1VPN auto-discovery
mechanism is to support the "single-end provisioning" model, where
addition of a new port to a given L1VPN would involve configuration
changes only on the PE that has this port and on the CE that is
connected to the PE via this port.

In the body type:

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.
