Hi Vasselin,
There's no dialer-group on R5 to bind the dialer-list to the interface.
Besides that we don't see your dialer-list here, have you included echo
AND echo-reply?
Have you created username/password on the routers?
Cheers,
JP
BTW, you shouldn't say what was on your exam, think of the NDA mate.

Subject: Loosing easy points in the LAB - ISDN
Hi guys,
What do you think about loosing points in the LAB that you think you
deserve?
Did that happen to you?
I was just making simple ISDN configuration and I thought how many
things could get wrong in such a task. Let's say I have that:
"Configure ISDN on R3 and R5.
Configure authentication which is not transmitting the whole password
across the network. Use password 'cisco'.
When the link utilization reaches 50%, the second link should be brought
up.
The routers R3 and R5 should ping the remote end of the ISDN link. Only
R5 should be able to dial."
Well, that is pretty simple... But then I started thinking....
Here is the config:
R5:
interface BRI0/0
ip address 192.168.35.5 255.255.255.0
encapsulation ppp
dialer idle-timeout 0
dialer map ip 192.168.57.0 name R3 broadcast 1122334455
dialer map ip 192.168.35.3 name R3 broadcast 1122334455
dialer load-threshold 128 either
isdn switch-type basic-net3
ppp authentication chap
ppp chap password cisco
ppp multilink
R3:
interface BRI0/0
ip address 192.168.35.3 255.255.255.0
encapsulation ppp
dialer idle-timeout 0
dialer map ip 192.168.35.5 name R5 broadcast 11223344
dialer load-threshold 128 either
isdn switch-type basic-net3
ppp authentication chap
ppp chap password cisco
ppp multilink
!
So, a lot of questions appeared:
Am I using the right authentication?
Am I using the right encryption type?
What is the difference between " dialer load-threshold 128 either",
"multilink load-threshold 128 either" and "ppp multilink load-threshold
128 either"? What is the right command between these three?
Am I doing the right map?
May be these questions are stupid... May be my configuration is
correct... But I know it isn't since I had similar configuration in my
LAB and got zero points. What if I have that one next time? I know it is
working, but still the most important thing is the POINTS!!!
What do you think about it?
What is the right configuration?
Did you also loose the "easy" points?
p.s While we are still on ISDN I would like to ask you when would you
use the following command:
"no peer neighbor-route"
