Hi..Everyone..

Does Who know the answer ????
Thanks..

Diagram

R1-(bri0 1.1.1.1)--ISDN--(bri0 1.1.1.2)--R2
| |
S0(2.2.2.1)-------------------------S0(2.2.2.2)
---------
Question
---------
-Configure DDR on R1 & R2 so the ISDN-link only comes up if R1's
S0-interface goes down.
-Only R1 should initate the call !!!

My answer

R1>
username R2 password 0 cisco
!
interface Serial0
backup interface BRI0 **
ip address 2.2.2.1 255.255.255.0
interface BRI0
ip address 1.1.1.1 255.255.255.0
encapsulation ppp
dialer map ip 1.1.1.2 name R2 broadcast 2222222 **
dialer-group 1
isdn switch-type basic-5ess
cdapi buffers regular 0
cdapi buffers raw 0
cdapi buffers large 0
!
dialer-list 1 protocol ip permit
R2>
username R1 password 0 cisco
!
interface Serial0
ip address 2.2.2.2 255.255.255.0
interface BRI0
ip address 1.1.1.2 255.255.255.0
encapsulation ppp
dialer map ip 1.1.1.1 name R1 broadcast ***
dialer-group 1
isdn switch-type basic-5ess
cdapi buffers regular 0
cdapi buffers raw 0
cdapi buffers large 0
!
dialer-list 1 protocol ip permit
=>Because The question needs that Only R1 should initate the call,
So I omitted the Dialsting#(1111111) of R1 in the Dialer-map of R2's Bri0
(dialer map ip 1.1.1.1 name R1 broadcast ***)
=>If I shut down the S0 of R1, The Bri-link between R1 & R2 is UP ..
But When i ping the R2's BRI0(1.1.1.2) with a source R1's Bri0(1.1.1.1),
It failed !!
=>But When i add a Dial string# in R2 such as "dialer map ip 1.1.1.1 name R1
broadcast 1111111", The ping is O.K!!!
=>My Question is that I must always configure Dial sting # in R1 & R2's BRI0
??.
and if i do it, Can R2 also intiate the call ??
=>So The Question,"Only R1 should initate the call " has no meaning !!!
How can i fix the problm ????
Help me..
I'm sorry for my poor English..
