Rob,
The RIP sender sends RIP only to gateways listed in the encap table,
unless a bug has surfaced that I wasn't aware of. That code has been
stable for several years, so I doubt it.

Lately I see a number of gateways that are registered
without subnets, but still they send traffic.
When tracing it, it appears to be usually traffic like MikroTik neighbor discovery.
It gets logged in our firewall because it is IP-encap traffic coming from an address that
is not in the
IP-encap routing table.?? And it isn't in the IP-encap routing table because that
gateway does not have
subnets.
Would it be an idea to not send the RIP announcements to gateways without a registered
subnet?
It would not be useful to them anyway, I think.
