Thank you Tom for documenting your trials. Every little bit helps the
next guy all that much more.
I don't think we'd be deleting gateways just because they're rejecting
RIP, certainly not in a short period of a month or two. I'm not sure
what factors we can use to determine whether a gateway is out of service,
but just rejecting RIP isn't enough.
The primary reason for detecting ICMP unreachable replies to RIP
transmissions is to avoid annoying people who aren't gateways anymore -
in particular, people who have inherited a dynamic address that used
to be a gateway. What I do is turn off RIP transmissions to that
particular address for the duration of the RIP transmission cycle,
so that they only get ONE packet every 5 minutes instead of two dozen.
I don't want to have to field complaints from innocent bystanders whose
firewalls are set to be too sensitive and verbose. And I do get those.
