Re: RFC 9985 on Optimizing Bidirectional Forwarding Detection (BFD) Authentication

[Manav Bhatia <[e-mail]>]

11+ years in the making, and we finally did it!

I want to extend my deepest gratitude to everyone in the WG, and especially
to my brilliant co-authors. Thank you all for your immense hard work,
endless patience, and perseverance over the last decade. It’s been an
absolute privilege working with you all.

Thanks, Manav
