[Idr] WGLC is for "BGP Router Capabilities Attribute” [was: Re: WG LC for draft-ietf-idr-entropy-09 (8/29 to 9/12/2023)]

[John Scudder <[e-mail]>]

Hi All,

Robert Raszuk pointed out [1] that the draft filename (draft-ietf-idr-entropy) doesn’t clearly reflect the title and scope of the spec — the title is "BGP Router Capabilities Attribute”, and indeed the ELCv3/Entropy Label Capability is only one example of a capability the RCA can contain.

As a reminder, we ended up with this filename because the draft is a merger of draft-ietf-idr-next-hop-capability and draft-ietf-idr-entropy-label, and that was the one we picked to merge down to. In retrospect maybe we should have merged down to draft-ietf-idr-next-hop-capability instead, or even picked a third, new, filename. 

I’ve adjusted the subject line to spotlight this fact, because Robert expressed concern that WG participants might not realize what the WGLC is about, and I promised [2] to follow up.

Thanks,

—John
