I have to disagree.
My config that I recently did for an OSPF demand circuit said to only
allow one side to initiate the call & I did not use a dialer map on both
sides, (The side that initiated the call called the other BRI port &
brought it up.) however I did need a dialer list to permit the traffic,
or the pings would not work.
At least that is the way that I got it to work. I did not think that I
needed the dialer-list either, but when I did not have it applied the
pings would not go through. After I applied it everything worked fine.
Even without the dialer map on one side.

Both sides need to dial in to the isdn switch, so it makes sense that
both
sides need to know the number to dial.
To have only one side capable of "initiating" a call, it seems that
you
would only put a dialer-list on one side (or a very restrictive dialer
list
on the side that doesn't initiate calls).
Thank you,

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
