Hi, 

I have reviewed this document as part of the security directorate's ongoing
effort to review all IETF documents being processed by the IESG. These comments
were written primarily for the benefit of the security area directors. Document
editors and WG chairs should treat these comments just like any other last call
comments.

The document creates a registry to avoid misinterpretation of the packet part of an MPLS packet and better parse of load balance the MPLS packet.
