Hi all, I have a few questions regarding the expired EVPN Interoperability Modes<https://datatracker.ietf.org/doc/html/draft-ietf-bess-evpn-modes-interop-02> draft. 1. Do the authors plan to refresh the expired WG draft? Please note that: * It has been expired for ~4 months already * It does not appear as a goal in the list of WG goals? 2. Assuming that the draft is not abandoned, what is its intended status? I am asking that because: * The draft itself states that its intended status is Informational * At the same time, the draft clearly defines some changes in the standard-defined procedures, e.g.: i. Section 3.1.1 states that an EVI that implements VLAN-aware VLAN bundles service interface and contains a single BD must "allow to send and receive zero EtherTag". This contradicts the definitions in Section 6.3 of RFC 7432<https://www.rfc-editor.org/rfc/rfc7432.html#section-6.3> ii. Section 3.2 states that an EVI that implements VLAN-based service interface "MUST allow receiving of non-zero EtherTag". This contradicts the definitions in Section 6.1 of RFC 7432. I also have to admit that I do not understand why an EVI with a single BD should ever be considered as implementing VLAN-aware Bundle Service Interface. Your feedback will be highly appreciated.
