Hi Tony,

The SIGALRM is just the signal sent by the kernel as a result of a timer
set up by ampr-ripd to trigger 30 sec from receiving the last RIP
routing set and is an expected behavior.
It triggers the purging of obsolete route entries and has nothing to do
with the update of the routing tables, which happens on the fly via a
netlink socket during RIP processing on reception.

If the encap.txt is correctly saved, that means that the RIP data was
parsed successfully and sent to the kernel.

What kernel version do you use?
Can you post your ampr-ripd command line used to start up the daemon?
