	The above route add command will cause packets destined to 44.255.259.* to be dropped on the floor, unless a more specific route (such as 44.255.259.0/25) exists. If you route the whole /24 subnet to your radio interface, the blackhole route should not be used. If you have smaller subnets or per-host routes for each user host, the blackhole route will prevent packets destined to unused addresses from getting into a loop between your gateway and the Amprgw.

	After confirming that it works, move it to /usr/local/sbin (or something) and put it in your boot scripts (~~sorry, no sysv init script provided yet~~).

	RIP ([http://en.wikipedia.org/wiki/Routing_Information_Protocol Routing Information Protocol]) is a method to dynamically update IP routing tables. In practice, on the [[AMPRNet]] [[Gateway]], it removes the requirement to periodically download the tunnel routing table ([[encap.txt]]) using FTP and apply it to the routing table. It transmits changes quicker and should be simpler to set up. Amprgw transmits the RIP routing table updates every 5 minutes, while the encap.txt has traditionally been only updated once per day. Some operators have even done the downloads manually (and not very often).

	The RIP protocol is used in a slightly unconventional way on the ~~Amprnet~~, and the standard IP routing daemons such as zebra/quagga are not able to process these packets.

	rip44d is written in the Perl programming language. C might be the conventionally right language to implement daemons such as this, but the author happened to have a good bunch of perl code that could be easily reused in the implementation of rip44d.
