[Last-Call] Re: Last Call: <draft-ietf-pce-segment-routing-policy-cp-18.txt> (Path Computation Element Communication Protocol (PCEP) Extensions for Segment Routing (SR) Policy Candidate Paths) to Proposed Standard

Hi All,

While working on related IDR documents, I've come across some issues
with the IANA consideration section of this document and would like to
suggest a way to address/resolve them.

Section 6.5
The new SR Policy Protocol Origin registry created under the Segment
Routing registry group is shared between this document and
draft-ietf-idr-bgp-ls-sr-policy. However, the allocation policy is not
aligned between the two - Specification Required vs Expert Review.
There is also a private use space. To harmonize them, I would like to
suggest that the allocation policy for range from 0-125 be retained as
Specification Required (as per this PCEP document) and the FCFS be
used for 126-255. I believe this would meet the requirements of both
the documents and also avoid the private use space.

Sections 6.7 (SR Policy Invalidation Operational Flags) and 6.8 (SR
Policy Invalidation Configuration Flags) are PCEP specific and the
right place to park them should be under the PCEP Numbers registry
group rather than the currently proposed Segment Routing registry
group. The Segment Routing registry group is where we keep codepoints
shared by multiple protocols.

Thanks,
Ketan
