Actually I stand corrected. Bill Lijewski is correct - newer IOS versions
now have a "ppp authentication chap callout" command (as opposed to just a
"callin" parameter).
That's the command you'll want to use on R3 to satisfy your requirements.
Great job Bill!

Tony,
I agree that everything else in the question points to using "ppp
authentication chap callin". Kaiser probably just reversed the two router
names.

I think you are correct.
I read his question too fast.
He is either not stating all of the requirements or he has
stated it
backwards. But I believe he is trying to get to callin.
Thank you for pointing that out.

Subject: RE: isdn question
Actually Tony, I disagree. "ppp authentication chap callin"
should be used
on a router so that challenges are made only on INCOMING
calls, not outgoing
calls.
Now in Kaiser's question, he said "If R1 calls R3. R3 should
not challenge
R1". Well if R1 is doing the calling, "ppp authentication
chap callin"
configured on this router will cause R1 not to challenge R3,
but R3 will
challenge R1. If we put "ppp authentication chap callin" on
R3, the call
would be considered incoming from R3's perspective and R3
WILL in fact
challenge R1.
Seems to me that R3 will always challenge R1 when R1
initiates the call to
R3 no matter where "ppp authentication chap callin" is
placed.
Someone please correct me if I am wrong.
Thanks,
Ken

Sorry about my previous post.
I forgot the authentication in the "ppp
authentication chap callin"
command.
It looks like you already had the answer in one of
your other posts.
