The data I've observed suggests that if an upstream router returns
some kind of error for a gateway --- specifically, I've observed ICMP
Host Unreachable messages --- that induces AMPRGW to stop forwarding
for an endpoint for ~1 hour. I haven't looked at the internals of
`ampr-ripd` that closely, but it seems sort of strange that just
stopping it would induce that behavior. Perhaps it has to do with
tearing down tunnels and/or routes when `ampr-ripd` starts/stops.
Chris, do you have any insight into this behavior?

IIRC is it something like 60 minutes depending on when your station
last flapped, and you will see RIP traffic distributed over the IPIP
tunnel. Note that as far as it is concerned, the flap is when amprripd
exits and restarts.
