Document: draft-ietf-idr-rfc3392bis-02.txt Reviewer: Elwyn Davies Review Date: 12 December 2008 IETF LC End Date: 25/12/2008 IESG Telechat date: (if known) - Summary: The document is almost ready for the IESG. However after diligent searching both in the RFCs and on the IANA web site, I believe that neither the original BGP RFCs 1771/4671, RFC 3392 nor this draft define a registry for the parameter types in OPEN messages. The CAPABILITY parameter is said to be 'Type 2'. I presume this means the value of Parameter Type in the sense of s4.2 of RFC 4671. BTW: Is there a 'Type 0' or 'Type 1'? There is also one minor nit and a clarification which would help. Comments: IANA Considerations: There does not appear to be a registry for OPEN message (optional) parameter types! s4: I think it would be helpful to naive readers to make it clear that the capability (sub-)TLVs all go 'inside' the overall CAPABILITY parameter TLV in the OPEN message, and the overall length in the Parameter TLV covers the whole set of capability options (and in turn the total length of all the optional parameters.... you could run out of space just counting the counters ;-) ) s4: The encodings of the Capability Type and Length fields are not specified.
