I think in generally routing protocols do not have route 'informational
only' packets for neighbors. You need to use management traffic (telnet,
console...). I can think of one exception, but there are probably more.
I believe you can force a Rip neighbor to send an update packet that when
received the router ignores the routes inside and will not try to install
them, but will display for you as a sort of troubleshooting technique
without using telnet. If their is a far neighbor running passive interface,
it will not send any updates. But you need to see its table. If you send a
request using udp port not equal 520, the passive neighbor will reply. I
tried but couldn't get it to work on IOS, and maybe the update will still be
susceptible to filters on the other side anyway?
For lab BB, rely on your data links in and out of backbone and details of
what you sent and received to infer correctness. Assume worst case scenario
on the BB and predict the possibilities.
