Most of the time, we do weird things because the lab says so. :)
Real life is much simpler!

YEP, you are correct, but i still don't understand the question, if it's
just matter of peering, then the "neighbro ebgp-multihop" should cover that,
unless he was asked not to use that, which means that the "ttl-security"
command will accomplish that task. But if it's matter of only allowing
prefixes with X amount of AS numbers in the As-path list then it's
"maxas-limit".
But you are correct.

That would assist you with limiting individual updates and how many "hops"
away they are. I took his question meaning to establish the bgp connection
to begin with since he mentioned ebgp-multihop...
So I guess it depends on whether we're talking about the connection itself,
or within the connection!

I don't know the entire topology and the actual question but MAYbe the "bgp
maxas-limit" can also help.

I'd suggest looking at a neighbor command having to do with "security" and
see what kinda description may fit your need.
Or since we know that ebgp-multihop has to do with a measurement of TTL,
searching through the command reference about other things dealing with ttl
may help as well.
