Re: [Idr] WG adoption call for draft-scudder-idr-entropy-label-01 (9/6/2022 to 9/20/2022)

Aijun,

Work on RFC6790 started in 2008.

Mean time there are real networks running which need signalling solutions.
This is not green field nor IETF only game to produce RFCs.

There are practical aspects of protocol extensions addressing real needs.
And even if I-D.ietf-idr-next-hop-capability would become an RFC tomorrow
it is non-transitive so not only upgrade to egress and ingress is needed
but also BGP RRs RSs ASBRs with no-next-hop-self etc ... would need to
recognize it in order to propagate it.

Lastly, I am not sure what is the time unit - when you are referring to
"hurry" in IDR WG :)

Best,
Robert
