[Babel-users] Restarting MeshPoint – seeking advice on routing for crisis/disaster scenarios

While they are not intended to deal with deliberate jamming, there's
a bunch of mechanisms in Babel that are fairly effective at avoiding
oscillations.  See Appendix A.3 of RFC 8966, as well as the discussion in
Section 4 of RFC 9616.

The algorithm in Appendix A.3 is designed to mitigate oscillations in the
presence of a feedback loop; in the absence of a feedback loop, it will
bias in favour of stable routes.

It's on topic, don't worry.
