ISDN dial-up Not working correctly

[nichols]

Hi Nichols here again, struggling again with ISDN dail up as it is the bain of my life.

I am configuring a cisco 4000 series router to use ISDN dial up to connect to a cisco 800 series router on another site.

I have configured the bri1 port as below:

interface BRI1
description isdn dial up connection to Leeds
ip address 192.110.96.1 255.255.255.0
encapsulation ppp
bandwidth 64
dialer map ip 192.110.96.2 name leeds xxxxxxxxxxx
dialer-group 1
isdn switch-type basic-net3
ppp authentication chap pap
ppp chap hostname hayroute3
ppp chap password 7 1101181C051D1E180179
ppp multilink
!

I have configured a dialer-list command as below:

dialer-list 1 protocol ip permit

When I try to ping leeds i don't get a connection. I have debuged dialer events and get the following error message:

Password:
hayroute3>en
Password:
hayroute3#debug dialer events
Dial on demand events debugging is on
hayroute3#terminal monitor
hayroute3#ping 192.110.26.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.110.26.1, timeout is 2 seconds:

5d05h: BRI1: Dialing cause ip (s=192.110.96.1, d=192.110.26.1)
5d05h: BRI1: No dialer string, dialing cannot occur.
5d05h: BRI1: Dialing cause ip (s=192.110.96.1, d=192.110.26.1)

5d05h: BRI1: No dialer string, dialing cannot occur.
Success rate is 0 percent (0/5)
hayroute3#


because of this I changed the dialer map command to a dialer string command as shown below:

interface BRI1
description isdn dial up connection to Leeds
ip address 192.110.96.1 255.255.255.0
encapsulation ppp
bandwidth 64
dialer string xxxxxxxxxxx
dialer-group 1
isdn switch-type basic-net3
ppp authentication chap pap
ppp chap hostname hayroute3
ppp chap password 7 1101181C051D1E180179
ppp multilink

This time the line works and repeatedly goes up and down and gives the following error message:

5d03h: BRI1:1: disconnecting call
5d03h: BRI1: Dialing cause ip (s=192.110.96.1, d=224.0.0.10)
5d03h: BRI1: Attempting to dial xxxxxxxxxxx
5d03h: %LINK-3-UPDOWN: Interface BRI1:1, changed state to up
5d03h: %LINK-3-UPDOWN: Interface BRI1:1, changed state to down
5d03h: BR1:1 VP: Cleaning already proceeding
5d03h: BRI1:1: disconnecting call
hayroute3#termina
5d03h: BRI1: Dialing cause ip (s=192.110.96.1, d=224.0.0.10)
5d03h: BRI1: Attempting to dial xxxxxxxxxxx
5d03h: %LINK-3-UPDOWN: Interface BRI1:1, changed state to up
5d03h: %LINK-3-UPDOWN: Interface BRI1:1, changed state to downl no

even when this happens I still cannot get a ping from the remote server.

Please help as I am banging my head against a brick wall with this one!!!

Cheers
Nichols

Hi Nicole:
I have similar ISDN problem.
can I send you my configs to look at?


thanks

 

[nichols]

Ill have a look but I'm by no means an expert!

If you post it on this site with both configs others will have a look also. As people like Wybnormal, Cerati, asdsa and Kenlulee are probably a lot more qualified to help!


Cheers

Nichols
