The IESG has approved the Internet-Draft 'VCID Notification over ATM link for LDP' <draft-ietf-mpls-vcid-atm-05.txt> as a Proposed Standard. This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are David Oran and Rob Coltun. Technical Summary This document specifies the procedures for the notification of VCID (Virtual Connection IDentifier) for an ATM-LSR (Label Switching Router). Because the ATM layer labels (VPI and VCI) associated with a VC rewritten with new value at every ATM switch nodes, it is not possible to use them to identify a VC in label mapping messages in the LDP. The concept of VCID is introduced to solve this problem. VCID has the same value at both ends of a VC. This document specifies the procedure to share the VCID value between ATM-LSRs. Working Group Summary There was consensus in the WG for this document with no major objections. Protocol Quality Currently, there is no complete implementations. However there are implementations in progress. There is an implementation of VCID procedure based on FANP (RFC2129) which is almost same as the VCID notification for LDP, specified by the VCID document. The draft was reviewed by Rob Coltun for the IESG.
