I have a network with 3 2600 series routers using ddr over ISDN and Serial . Dialer maps work and there is network connectivity . However I need to connect a

fourth router a 1601 also using ddr over serial lines to connect to the network. The problem is once the modem connects to the router #1 I can't ping through to the other rotuters The routes are there but I can't get out. Welcome any suggestions.

Greetings:

Not sure. I need to see the IP addresses/mask on each port in the routers plus the static routes in each.

Thanks...Steve

Hi,

From your configs it shows that you are using the same network on ISDN and on your serial interfaces on router 3. This is never a good idea.

Try using a unique network adress&mask for each link.
