ISDN backup using dialer profile !!

chungandrew · ‎02-12-2007

I have a configuration for ISDN BRI to backup Lease line . The configuration is as below :

--------------------------------------

interface BRI0/1/0

no ip address

encapsulation ppp

dialer pool-member 1 max-link 2

dialer pool-member 2 max-link 2

isdn switch-type basic-net3

isdn point-to-point-setup

no fair-queue

no cdp enable

ppp multilink

!

interface Dialer1

ip address 192.168.202.18 255.255.255.0

ip pim sparse-dense-mode

encapsulation ppp

dialer pool 1

dialer remote-name XXXXXXX

dialer idle-timeout 300

dialer string 0221926061

dialer string 0281924802

dialer load-threshold 128 outbound

dialer-group 1

no cdp enable

!

interface Dialer2

ip address 192.168.206.18 255.255.255.0

encapsulation ppp

dialer pool 2

dialer remote-name XXXXXXX

dialer idle-timeout 300

dialer string 2200986

dialer string 2200987

dialer load-threshold 255 outbound

dialer-group 1

no cdp enable

-----------------------------------------

The problem is that I found the BRI never call the calling string configed in the second dialer profile(dialer 2) even though I remove the configuration "dialer pool-member 1 max-link 2" from BRI physical interface (I can succeed to manually call these two numbers) , but it work for the two calling strings in dialer 1 , I am wondering if any problem exist in my configuration ?

Hi ,

If I am not wrong, Bri interface cann't be a member of two dialer pools

You can do one thing for cheching dialer interface 2 dialer strings..

configure the dialer pool 1 under dialer interface 2 and remove the dialer pool 1 from dialer interface 1.

Try to establish isdn connectivity and use debug isdn q931 for troubleshooting.

If possible paste the config.

Hi , Satish :

Ths for advise . But my another question is why it never attempt to call out using interface dialer 2 associated with dialer pool 2 while I just only leave "dialer pool-member 2 max-link 2" in interface B0/1/0 ?

HI ,

Can you do the following config changes and take ""debug isdn q931"" output from router with dialer pool-memeber 2 max-links 2 under bri interface.

username XXXXX password XXXXX

Int bri 0/1/0

ppp authentication chap.

ppp chap hostname XXXX

encapsulation ppp

dialer pool-memeber 2 max-links 2

int di2

ppp authentication chap.

ppp chap hostname XXXX

encapsulation ppp

and do the same config on END-B router also.

Thanks,

satish
