static routes

[meehanian]

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

[lgijssel]

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.

[meehanian]

Thank you, I will try that .
