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

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 summary of the review is: “Ready with issues.”

Issues Identified:

1. OAM and Security Considerations
- Section 9 mentions S-BFD (Seamless Bidirectional Forwarding Detection) as an
option for continuity checks. However, the Security Considerations section does
not reference RFC 7880, which defines S-BFD. Please consider adding this as a
security considerations reference for completeness. 2. Reference Updates - In
the PCEP Security Considerations section, the draft references
I-D.ietf-pce-segment-routing-policy-cp. This document is now published as RFC
9862. Please update the reference accordingly. - In the BGP section, the draft
references I-D.ietf-idr-bgp-ls-sr-policy. This is now RFC 9857. Please also
update this reference accordingly.

Suggested Editorial Improvements:

- Ensure consistency in terminology (e.g., “candidate path” vs “Candidate Path”
and "circuit-style" vs Circuit-Style" vs "Circuit Style"). - Verify that all
references in Section 14 are up-to-date and correctly formatted after RFC
promotions.
