I wholeheartedly agree with Acee's points.
It isn’t completely clear to me why the new Section 8 was written - as opposed to updating the existing Section 5. But if the authors/WG are OK with this presentation I won’t object - but two review points: 1)Section 5 states: "The following Sub-TLVs MUST be included as the Local Node Descriptors: ... - One or both of IPv4 and IPv6 Router-ID of the ASBR using TLV 1028 and/or 1029 [RFC9552], depending on whether the ASBR is configured with one or both of the IPv4 and IPv6 TE Router-IDs. (Note: while [RFC9552] introduced these TLVs for use in the BGP-LS attribute, this document also leverages the same TLVs for use in the NLRI.)” It isn't clear to me from looking at RFC 9086 where this information comes from in the case of “direct/static” as RFC 9086 specifies only TLV 516 for BGP Router ID. 2)Section 8 states: “Alignment between the two sides of the Inter-AS link (e.g. SB1 – TB1) …” I assume “TB1” is meant to be “TB2” as there is no node “TB1” in the diagram.
