Michael,
At this point, ampr-ripd (C implementation) is the best thing out
there in my opinion.
Hessu, wrote the rip44d, and that required Perl and a multicast
package to run. So running this on a WRT54G, for instance was
probably not going to happen. I'd like to think with the C
implementation, this could be a reality.
Also, I am not sure, but do think the C implementation stands the
greatest chance to run cross platform. Hessu's perl one was kind of
locked to Debian installs.
Again, it's all so new, I personally haven't had they time yet to try
it on a bunch of different platforms.
I actaully am not sure why someone would go with amprd over ampr-ripd.
Perhaps others can comment.
Steve
