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

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

And similarly congratulations to the authors and the WG for RFC 9986, the
 companion document for the ISAAC mechanism of implementing the optimized
 procedures.

This optimization enables BFD to scale better when there is a desire to use authentication where applying the same authentication mechanism to every BFD Control Packet may adversely impact performance. This optimization partitions BFD Authentication into a more computationally intensive (MCI) mechanism that is applied to BFD significant changes and a less computationally intensive (LCI) mechanism that is applied to the majority of BFD Control Packets.
