Authors, Some comments on the draft. 1. Section 3.1 SR Path Segment "Also, it can be used for identifying an SR candidate path or an SR Policy defined in [I-D.ietf-spring-segment-routing-policy<https://tools.ietf.org/html/draft-li-idr-bgp-ls-sr-policy-path-segment-01>]." When the path-segment is used for identifying SR policy/candidate path, The SR Path Segment sub-TLV should appear in the SR policy as below. Pls update figure 1. SR Policy SAFI NLRI: <Distinguisher, Policy-Color, Endpoint> Attributes: Tunnel Encaps Attribute (23) Tunnel Type: SR Policy Binding SID Preference Priority Policy Name Explicit NULL Label Policy (ENLP) Path Segment Bidirectioanl Path Segment List Weight Segment Segment The Path Segment Sub-TLV may be associated with SR Policy as well as the Segment List Simultaneously, or may be associated with SR-Policy or segment List alone based on usecases. 2. I suggest to update the IANA section, with code points and NLRIs/attributes where the TLVs/sub-TLVs appear in BGP-LS NLRI Along with the code-points. It's useful for implementors as well as IANA to keep the registry up to date. Rgds Shraddha
