Cisco 800 ISDN setup problems.

[adejordan]

Hi all

Have 2 cisco 801 routers connected via ISDN

I am able to get router1 to dial and connect to router2

Unable to get traffic to flow however.

Router1 -- E0 192.168.2.2 BRI0 (Dialer1) 192.168.3.1
Router2 -- E0 192.168.0.23 BRI0 (dialer1) 192.168.3.7

I have attached cut-downs of the configs. Please help!!

We only want Router1 to dial Router2, not the other way round.

On your Router 2, the default ip route point to the interface ethernet 0. You should point it to interface dialer 1:
ip route 0.0.0.0 0.0.0.0 dialer1 (as you did for router 1).

Regards.

Hi ewaterke

Changed the static route, and added a dialer-group 1 entry into the intBRI0 config on router 2

Still not getting any traffic flow - (Ping or above)

Gradually losing hair here!!!

Thanx

Hi,

(as you are using dialer map), instead of using a static route pointing to the dialer interface, you can try to use a static route pointing to the IP address of other router.
router 1: ip route 0.0.0.0 0.0.0.0 192.168.3.7
router 2: ip route 0.0.0.0 0.0.0.0 192.168.3.1

If this is not working, I'll need more info:

1. from router 1, can you ping 192.168.3.7 ?
2. If not, what is the staus of int dialer 1 when the routers are "connected" ?
3. Send me the last config.

Regards,

You ust configure ppp auhentication chap on the physical interface (BRI).
