Thank you for your liaison to the IETF CCAMP WG in response to their liaison on

This liaison is to inform you that a new working group has been formed within
the IETF's Routing Area to focus on developing protocol solutions for Layer One
VPNs. The charter of this working group can be seen at We encourage interested
parties to join the working group's mailing list by following the links on the
charter web page.

The L1VPN working group's work is informed by Y.1312 and Y.1313, and we thank
the ITU-T for making these documents available to IETF participants. As we
advance our work and publish Internet-Drafts we will keep SG13 informed of our
progress through the liasion process.

We would also like to thank Marco Carugi for communicating the current status
of L1VPN work within SG13 at our recent meeting at the 63rd IETF in Paris.

Looking forward to continued cooperation between our organizations.
