IDR and BESS WGs: draft-hares-idr-bess-tea-templates provides guidance for authors writing text to define tunnel TLVs of Sub-TLVs for the BGP tunnel encapsulation attribute (TEA) [See RFC9012].
The goal behind this draft (or the web version on the IDR wiki: (https://wiki.ietf.org/group/idr/TEA-templates) is to help new and experience authors quickly write correct text that has necessary information for interoperable standards. The non-goal is to cause rewriting of good text in your drafts. During IETF-122, I will review these guidelines (in BESS and IDR (Friday)) and provide working examples from the drafts specifying tunnels for SR, SDWAN, NV03 (geneve), and multicast routing. This draft is part of the IDR chairs continuing attempt to delays in publications. This draft comes with an offer to help write/edit text for Tunnel TLV or Sub-TLVs for the TEA attribute.

Currently proposed BGP specifications in the IDR and BESS Working groups have defined new tunnels and new parameters for these tunnels in Sub-TLV. The Segment Routing usage of the TEA has suggested a number of new Sub-TLVs. This document provides guidelines to help authors quickly write correct text for new tunnels (defined in tunnel TLVs) and new Sub-TLVs. These guidelines are given as "templates" to aid new authors. More experience authors should view these templates as a list of expected content. One additional challenge for tunnels using the PMSI tunnels is to carefully define the interaction between PMSI tunnels and TEA tunnels. The IETF Secretariat
