So we would remove Section 3.7 plus the few references to it elsewhere in the document? That seems fine, thanks for catching this. We also get to eliminate a normative reference dependency. :-)

IDR WG, if anyone has an objection, please raise it — but it seems like an open-and-shut case.

Thanks,

—John

Hi authors,
Cc’ing John and Alvaro as the document has left IDR WG.

TL;DR: I think that you should remove “an "IPv6 SID (Segment Identifier)" TLV,”

https://tools.ietf.org/html/draft-ietf-idr-tunnel-encaps-14#section-3.7<https://urldefense.com/v3/__https://tools.ietf.org/html/draft-ietf-idr-tunnel-encaps-14*section-3.7__;Iw!8WoA6RjC81c!VsJ456XB1LS-76ORABaTDwi2kEMtkvSglVu1GBspWDKTjkG7UKKk9Dn1oAQ_sg$> says:

   [I-D.ietf-idr-bgp-prefix-sid] defines a BGP Path attribute known as
   the "Prefix-SID Attribute".  This attribute is defined to contain a
   sequence of one or more TLVs, where each TLV is either a "Label-
   Index" TLV, an "IPv6 SID (Segment Identifier)" TLV, or an "Originator
   SRGB (Source Routing Global Block)" TLV.


Actually latest version of [I-D.ietf-idr-bgp-prefix-sid] has removed the support for "IPv6 SID (Segment Identifier)" TLV


The value 2 previously corresponded to the IPv6 SID TLV which was

   specified in previous versions of this document.  It was removed and

   usage of the BGP Prefix-SID for Segment Routing over the IPv6
