Yes, looks good. I tried it out, took out the dialer map on the non
initiating side, and it all works. Not sure how though, how it would get the
mapping for the other side.
I would assume that there is no way of not using dialer maps on both sides
if it was a callback scenario.

Yeah like I said... At least I know mine works...
Might not be proper in theory, but I met all the specs of the lab I was
attempting, so it must be correct?!?!

You're correct, that's it you need the dialer-group not the map. That
rings
the bell.

No problem. I couldn't get it too work without a dialer-list on both
sides. My pings would not go through.

I disagree, a dialer map statements map layer 3 address to an isdn
telephone
number. With out a map statement no traffic is passed. If you want to
have
one side dial and the other only answer the don't include the
dialer-group.

If you are running a routing protocol like an OSPF demand circuit you
should only need a dialer map on the side that you want to initiate
the
call.
You need to allow for interesting traffic on both sides though.
At least that is the way that I have been doing it.

Hello Group,
I'm having a little confusion here regarding ISDN dialing out only
from
one
side, so the other side is not allowed to initate a call. From what I
have
tested before, the dialer statements below should work.
dialer map ip 138.1.35.2 name R5 broadcast
dialer map ip 138.1.35.1 name R3 broadcast 2222
But the only way I can get pings to reply is by adding a number at the
end
of the first dialer map:
dialer map ip 138.1.35.2 name R5 broadcast 1111
R5 does dial out and establishes connection, but it looks like R3 does
not
know how to respond.
Am I missing something?
Albert
