I have reviewed this draft. And asked help from James Carlson to understand some of the number space issues in PPP (thanks!)
The draft is basically OK, but I have a few suggested editorial changes. These relate mostly to readability, so I'm not considering them blocking for starting the IETF Last Call. I would like to ask Srihari to update the document with these specific changes, however, and preferably in the next couple of days so that other readers do not have to struggle with the same questions that I had. ---- The document header should indicate "Obsoletes: 2472". Add to the end of the last paragraph of Section 1: "Together with RFC 5072 [2], this document obsoletes RFC 2472. However, no protocol changes have been introduced over RFC 2472." Change in Section 2.1 as follows: OLD: No IPv6-Compression-Protocol field values are currently assigned. Specific assignments will be made in documents that define specific compression algorithms. NEW: IPv6-Compression-Protocol field values have been assigned in [RFC2023] for IPv6 Header Compression (004f), [RFC2507, RFC3544] for IP Header Compression (0061), and [RFC3241] for Robust Header Compression (ROHC) (0003). Other assignments can be made in documents that define specific future compression algorithms. Replace the IANA Considerations section with the following text: No specific action is needed for the assignment of a value for the Type field of IPv6 datagram compression option specified in this specification. The current assignment is up-to-date at [4]. No action is needed either for the assignment of the IPV6-Compression-Protocol values, as such values have already been defined by other documents listed in Section 2.1. Values for this field are always the same as the PPP Data Link Layer Protocol field values for that same compression protocol. As a result, future allocation of these values is governed by RFC 3818 [8] that requires IETF Consensus.
