Re: [Idr] WG Adoption call for draft-dawra-idr-bgp-ls-sr-service-segments-05 (7/27 to 8/27)

Hi Sue,

I support adoption. I have some comments that can be handled at the
author's discretion.

- Figure 1 gives an impression that SR-C is directly connected to the
network node. I would just draw SR-C on top without showing how SR-C
connects to the network. How SR-C receives BGP-LS updates is not new and
thus just a reference to BGP-LS rfc7752bis is fine!

- Reference to SFC architecture RFC 7665 should be added to the
introduction.

- Section 2 s/Service SID MAY only be encoded as LOC:FUNCT/SRv6 Service SID
MAY only be encoded as LOC:FUNCT/. Further, I think it would be useful to
add why ARG is not to be used.

-  Function Identifier needs reference (I-D.
ietf-spring-sr-service-programming)

- Figure 2, closing parenthesis missing for ST

- I agree with the suggestion that ST should refer to the existing IANA
registry [1] instead of creating a new one in section 4.1

- The document says "Another Optional Opaque Metadata(OM) TLV of SRv6 SID
NLRI.."; is this only for SRv6?

- Is the expectation for the Flags in OM TLV that they would be applied for
all Opaque Types? Since no flags are currently defined for this as well as
SC TLV, some guidance would be useful as well as a possible IANA registry.

- Section 4.2, I could not find Segment Routing Function Identifier(SFI)
registry in any of the referenced documents. Is it new? In that case, the
text does not match!

- Section 6.1, could use some information about setting the opaque types

Thanks!
Dhruv
