[External Email. Be cautious of content]


Hi Loa, WG,

I support the adoption of this work, it provides a useful functionality that has been described well enough to be adopted by the WG.

I do have a few suggestions and nits that the authors could take up later -

--

- I suggest adding a few more lines to build some context in your Introduction section, the current text works for someone in the know-how of MPLS-OAM/SR but fails to provide context for a general reader.
<shraddha> Sure. -07 will address this

- I suggest to expand the text in section 4, to clearly state that this I-D is further specifying 3 more new sub-TLVs and also which TLVs would carry these sub-TLVs etc.
<Shraddha> yes. -07 will address this

- Some of the references mentioned as Informative are more suitable as Normative, namely - [I-D.ietf-spring-segment-routing-central-epe], RFC 2119, RFC 8174, RFC 8690 (?)
<shraddha> I have moved RFC 2119, RFC 8174, RFC 8690 To normative but I-D.ietf-spring-segment-routing-central-epe Doesn't seem to be normative. The IDR protocol extension for BGP-EPE is already a normative document.

Nits
- Abstract, you expand Segment Identifiers (SID) NOT on first use but much later.
- Introduction, s/mpls/MPLS (multiple places)
- Section 2, s/e-BGP/EBGP (as per RFC Editor abbreviation preference)
- Section 4.1, Change ipv4/ipv6 to IPv4/IPv6 (multiple places)
- Section 4.1, Expand FFS!
- Section 5, s/SHOuLD/SHOULD
- Section 5, fix the over-running lines (exceeding 80 chars)

--
<shraddha> Thanks for catching these. Will address all of them in -07
Regards,
Dhruv
