Hi, I'll offer my versions of answers to your questions: On Fri, Aug 21, 2026 at 12:50 PM luanshenshen via dev < dev@lists.frrouting.org> wrote:

*Questions*

1. Is anyone already working on RFC 9666 in the community that I should coordinate with?

I'm not aware of anyone else working on this; let's see whether there are replies to your email.

2. Given the Experimental status of the RFC, how would maintainers prefer this to land — a feature-gated series of small PRs, or one larger PR?

In general, it's easier for us to absorb smaller, "incremental" PRs, just for practical time-to-review reasons. If it's possible to offer work in increments, that'd be helpful. 3. Would you prefer I open a GitHub issue to track the design first, or go

straight to a Draft PR for directional feedback?

It's not required to have a "tracking" issue, but it can be helpful, to supply a common rendezvous point for doc references, discussions that might span multiple PRs, etc. Thanks, Mark
