Thanks Jorge. I had defined 3 bits in L2-GW-Proto, in anticipation of more/many load-balancing modes... but that now seems somewhat aggressive. I don’t mind scaling back down to 2-bitfield or just a new SFA bit by itself.
Another suggestion could be to create the registry directly with draft-7432bis ?

One of the two draft should start a registry in the IANA section. Stephane, chairs, any preference where this should reside? @Luc, about this: “This has come up before for e.g. draft-ietf-bess-evpn-l2gw-proto which requests a 3-bit field for load-bal modes.” Since the single-active bit (all-active if set to 0) is specified in RFC7432 and draft-7432bis, I assume the l2gw draft would only request one bit of the registry, and not a 3-bit field, right?

This has come up before for e.g. draft-ietf-bess-evpn-l2gw-proto which requests a 3-bit field for load-bal modes. Should one or the other draft request an IANA registry ?

This poll runs until *the 9th of Feb*. We are also polling for knowledge of any undisclosed IPR that applies to this document, to ensure that IPR has been disclosed in compliance with IETF IPR rules (see RFCs 3979, 4879, 3669 and 5378 for more details).
