Speaking as a WG member, I support publication.

I only have one functional comment and that is on Appendix A. Note that a key-chain or key-id would be useful for MD5 as well as TLS and TCP-AO. I’m not suggesting that you add MD5 since it is historic but support of MD5 as specified in RFC 5440 would require configuration of the same key or key-chain on the PCC and PCE server.
[Qin]: Good comment, I think we can add one statement at the end of the paragraph to say:
“
Irrespective of which security capability support is selected, the same key or key-chain on the PCC and PCE server should be configured.
”

I also have some editorial comments that you can decide whether or not to apply. Of note are that I don’t think you need to say “looking for connecting with a” and can simply say “looking for a”. Also, once this document is published the capability bits and sub-TLVs are not longer “new”.

See full set of editorial comments in attached RFC diff.
[Qin]: I agree with the most of comments and will incorporate them in.
One little tweak or fallback is s/ capability flag bit in the PCE-CAP-FLAGS sub-TLV in IS-IS is set to/ capability flag bit of PCE-CAP-FLAGS sub-TLV in IS-IS is set to
I think the original text is more clear here, using two ‘in’ is a little bit verbose in my view.
Thanks,
Acee

This begins a 3-week WG Last Call, ending on August 4th, 2021, for draft-ietf-lsr-pce-discovery-security-support. Please indicate your support or objection to this list before the end of the WG last call. The longer WG last call is to account for IETF week.
