It works for me anyways....

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.

Subject: Re: ISDN dial one way only
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
