ISDN backup for leaseline - need help

Hi,

I have two sites connected with a leaseline. I'm trying to setup a isdn line for backup but it doesn't work. Below is two routers config :

Router A

interface Serial0 ip address 192.168.245.1 255.255.255.252 ! interface Dialer0 ip address 192.168.246.1 255.255.255.252 encapsulation ppp no ip route-cache dialer pool 1 dialer remote-name jwtmumb dialer idle-timeout 300 dialer string 23889760 dialer-group 1 ppp authentication chap

ip classless ip route 0.0.0.0 0.0.0.0 Serial0 ip route 0.0.0.0 0.0.0.0 Dialer0 180

Router B

interface Serial0/0 ip address 192.168.245.2 255.255.255.252

interface BRI1/0 no ip address encapsulation ppp dialer pool-member 1 isdn switch-type basic-net3 no cdp enable ppp authentication chap

interface Dialer0 ip address 192.168.246.2 255.255.255.252 encapsulation ppp dialer pool 1 dialer remote-name fortipan dialer-group 1 no cdp enable ppp authentication chap

ip route 0.0.0.0 0.0.0.0 s0/0 ip route 0.0.0.0 0.0.0.0 Dialer0 180

- I did some test, unplug the primary connection on router A, but the isdn line did not kick in. Can any expert help me to check if any missign in my configuration ?

Many thanks :-)

You havent configure the dialer-list command to specify interesting traffic to dial the ISDN eg below

dialer-list 1 protocol ip permit

Hello,

in addition to what Elvis said, also make sure that you have the remote username adn password configured on your local routers:

Router A

username jwtmumb password xxxx

Router B

username fortipan password xxxx

Make sure the passwords match. In addition, you might want to specify the command 'backup interface dialer0' on your serial interfaces:

Router A

interface Serial0 backup interface Dialer0

Router B

interface Serial0 backup interface Dialer0

That way, the ISDN only kicks in when your serial interface line protocol goes down...

Regards,

Naz
