As you are aware, the IETF's Layer One VPN (L1VPN) working group has
been developing documentation to set out a framework and the
requirements for L1VPNs. This work draws on Y.1312 and Y.1313, and has
had significant
input from authors and reviewers who are participants in SG13.

The L1VPN working group now believes that it has completed the
framework and requirements, and proposes to take the document to
working group last call soon.

The relevant document can be found at
and, as always, we would appreciate any comments on the working group
mailing list. Details of how to subscribe to the mailing list can be
