How can I diagnose why my ampr-ripd is not receiving
the broadcast? Any
tools?
Likely your problem is caused by a kernel bug that was introduced some time ago, I
don't know if it has been fixed in the meantime or if it was defined as 'desirable
behaviour'
and left that way.
Some time ago I faced the same problem, and I could only fix it by adding the -r flag
("Use raw socket instead of multicast") to ampr-ripd. In multicast mode, which
used to
work fine, it simply did not work anymore on the Pi.

New subject: Help Not receiving ampr-ripd encap route broadcast
Thanks for the replys. I woke up this morning, checked, and saw the table
44 now filled with routes. So, the gateway is working again. I didn't do
anything. Maybe someone activated or sent me the broadcast.
I have this RPI2 updated with all the latest updates available and maybe
that can cause some problem if a bug is introduced. A few months back, on
my other RPI2 I remember installing the updates and causes my RPI2 to
freezed initiating an internal linbpq forward. Maybe some problem with
socat. So, in that RPI2 decided not to install any more updates and working
fine for now.
I will add the -r flag. Thanks for the tip.

If it works without it, don't.
The -r flag will make ampr-ripd receive ALL interface traffic and filter out
multicasts in user space, while in regular operation mode that's left to the
kernel and is more efficient.
While on a big system it probably doesn't make much difference, on a limited
resource device like the PI it could.
