Hello Venkat,
First of all you should have on your R4 config:
Dialer-list 1 protocol ip permit.
I was able to ping, I have 2 routers here is the config for R2:
interface BRI0
description r5 bri0
ip address 160.10.15.2 255.255.255.0
encapsulation ppp
dialer map ip 160.10.15.3 name R3 broadcast 5552002
dialer-group 1
isdn switch-type basic-5ess
cdapi buffers regular 0
cdapi buffers raw 0
cdapi buffers large 0
no peer neighbor-route
end
R2#ping 160.10.15.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 160.10.15.3, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 36/37/40 ms
R2#
06:26:31: %LINK-3-UPDOWN: Interface BRI0:1, changed state to up
06:26:32: %LINEPROTO-5-UPDOWN: Line protocol on Interface BRI0:1,
changed state
to up
R2#
Here is the config for R3 without the dialer-group defined:
interface BRI0
ip address 160.10.15.3 255.255.255.0
encapsulation ppp
dialer idle-timeout 0
dialer map ip 160.10.15.2 name R2 broadcast 5552001
isdn switch-type basic-5ess
cdapi buffers regular 0
cdapi buffers raw 0
cdapi buffers large 0
end
R3#sh run int bri0
What you need to do is take out the mapping all together, including all
of the dialer map statement on your R5. Once I take out the dialer map
all together on mine R3 on your R5.
R2#
07:03:46: BR0 DDR: Dialing cause ip (s=160.10.15.2, d=160.10.15.3)
07:03:46: BR0 DDR: Attempting to dial 5552002
07:03:47: %LINK-3-UPDOWN: Interface BRI0:1, changed state to up
07:03:47: BR0:1 DDR: dialer protocol up
07:03:48: %LINEPROTO-5-UPDOWN: Line protocol on Interface BRI0:1,
changed s
R2#
07:07:57: ICMP: echo reply rcvd, src 160.10.15.3, dst 160.10.15.2
07:07:57: ICMP: echo reply rcvd, src 160.10.15.3, dst 160.10.15.2
07:07:57: ICMP: echo reply rcvd, src 160.10.15.3, dst 160.10.15.2
07:07:57: ICMP: echo reply rcvd, src 160.10.15.3, dst 160.10.15.2
You see R2 is still calling R3, or in your case R4 will call R5, you
should have similar debug. That is from debug dialer.
Here is my config for R3 your R5 should be similar:
interface BRI0
ip address 160.10.15.3 255.255.255.0
encapsulation ppp
isdn switch-type basic-5ess
cdapi buffers regular 0
cdapi buffers raw 0
cdapi buffers large
end
Hopefully that will help solve your issue.

Subject: Re: RE : ISDN Issue..
hi roopa,
i tried that option too..basically, ISDN connection is initiated but
ping packets doesnt go thru..I get 0% success..
This is what I did:
On R5:
-----------
username r4 password CISCO
interface BRI0/0
ip address 187.1.45.5 255.255.255.0
encapsulation ppp
dialer idle-timeout 0
dialer map ip 187.1.45.4 name r4 broadcast 11110101
isdn switch-type basic-ni
isdn spid1 22220101
R4:
------
username r5 password CISCO
interface BRI0/0
ip address 187.1.45.4 255.255.255.0
encapsulation ppp
dialer map ip 187.1.45.5 name r5 broadcast 22220101
dialer-group 1
isdn switch-type basic-ni
isdn spid1 11110101
r4#p 187.1.45.5
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 187.1.45.5, timeout is 2 seconds:
*Mar 1 20:26:30.706: %LINK-3-UPDOWN: Interface BRI0/0:2, changed state
to up.
*Mar 1 20:26:31.726: %LINEPROTO-5-UPDOWN: Line protocol on Interface
BRI0/0:2, changed state to up..
*Mar 1 20:26:36.710: %ISDN-6-CONNECT: Interface BRI0/0:2 is now
connected to 22220101 r5..
Success rate is 0 percent (0/5)

Venkat,
I do observe a couple of things for u to change.I think what u have
interpreted and are doing is rt . But u need to change a little i
guess...
If u dont give the dial # then R5 wont be able to respond to the call. U
dont need to give the dialer-group cmd on R5 as that is what defines
interesting traffic. So without that R5 wont have anything to initiate
the call but if u dont give the dial # after bcast it wont know how to
call R4..
Make the changes and let us see what happens ??
R5:
-----
username r5 password CISCO <<<< shouldnt this be r4 and not r5
!
interface BRI0/0
ip address 187.1.45.5 255.255.255.0
dialer idle-timeout 0
dialer map ip 187.1.45.4 name r4 broadcast xxxxxx <<< u need to give the
dial #
isdn switch-type basic-ni
isdn spid1 22220101
end

Right, R5 is not allowed to call R4, but only R4 can make calls to R5.
the reason i used dialer idle-timeout 0 is that R5 should never
disconnect
Richard Dumoulin wrote:
I interpret "...R5 is not allowed to call R4..." as "do not configure an
isdn number under the dialer map command". As this is what you have done
I don't see anything wrong in putting the dialer-group.
I have noticed in Cisco papers that they always put it in the bri/dialer
interfaces. Then if they don't want to define interesting traffic they
just configure dialer-list protocol ip deny. So it seems to me that the
dialer-list command is good practice.
Also why have you configured dialer idle-timeout 0 ?

Objet : ISDN Issue..
hi
The question is that R4 can call R5 but R5 is not allowed to call R4..
When I do this via a PING the call gets setup but I do not get a
response...When I add the dialer-list/dialer-group commands to R5 it
works. Below is my config. I am using c3640-js-mz.122-15.T14 image on
both R4 & R5..How do I make Only one side initiate the call...?
R5:
-----
username r5 password CISCO
!
interface BRI0/0
ip address 187.1.45.5 255.255.255.0
dialer idle-timeout 0
dialer map ip 187.1.45.4 name r4 broadcast
isdn switch-type basic-ni
isdn spid1 22220101
end
R4:
-----
username r5 password CISCO
!
interface BRI0/0
ip address 187.1.45.4 255.255.255.0
dialer map ip 187.1.45.5 name r5 broadcast 22220101
dialer-group 1
isdn switch-type basic-ni
isdn spid1 11110101
end
!
dialer-list 1 protocol ip permit
