You're right, of course.
I think Rob made much the same points in an earlier email. - Brian

If the gateway doesn't use RIP, then it may also not open that port in its firewall. So it may either drop the packets silently or return ICMP unreachables. Right? If so, then the most we can say about this situation is that the site is not accepting RIP, not that something is "probably wrong". Or am I missing something?
Likewise, regarding a point made in an earlier email: the lack of traffic sent from a gateway to amprgw doesn't mean that the gateway is not operational. In our case, we use amprnet tunnels to communicate directly with other amprnet sites. And non-amprnet folks use our external IP. So, none of our traffic passes through amprgw.
BTW, I applaud all of the stats, Brian. It will help us detect problems we didn't even know existed. We just need to be careful about the conclusions we draw from the data. I know you are. I just didn't see the above points made yet (or perhaps I missed them).
