You may want to know if RIP indeed does trigger the dialing. So, to answer
your 2nd question, use the command debug dialer packets to give you a
rundown if RIP is considered an interesting traffic. If RIP is triggering
your ISDN, you'll see a debug output similar to the following:

Serisouly, what was the gist of the responses? Are NANOG types concerned
about routing protocol security vulnerabilities? I know that that there's a

Why isn't BGP a distance vector protocol?
Isn't the definition of a distance vector protocol in short- a routing
protocol that determines the distance to all destinations from itself using
information received from it's neighbors?
Well the big difference I can see with BGP is that it uses

Some routing protocols run right on top of IP, some on top of UDP, some on top

answer is a bit difficult.
Your best bet is to go to the RFC for the protocol of interest or RFC 1700,
