Both AHCP[1] and HNCP[2] are routing-protocol agnostic: while they were
both originally deployed with Babel, they work just fine with OLSRv2.  (I
happen to believe that's good design, unlike the autonomous configuration
protocols that people have in the past tried to build into OSPF, IS-IS and

We're still running AHCP, but we're deprecating it in favour of HNCP.
HNCP is not designed for mesh networks, and there are some reasons why
Henning and I think it will perform suboptimally in unstable meshes.
However, I'm opposed to extending HNCP until we get more experimental

So please use HNCP in your mesh, and let us know if it works well enough
(do let us know even if the answer is just "it works fine").  I'm probably
biased, but I would be grateful if you could deploy shncpd [3] (the other
implementation of HNCP is called hnetd).
