configuring cisco 837

[aquaguy]

Please help.

I need to program the router to direct all requests for onen ip address to a different router.

ie. all to the 837 router (10.10.10.1) for internet, accept 172.16.1.1 which needs to be directed through another router(10.10.10.100)

Thanks for any advise

To forward packets with *destination* 172.16.1.1 to router 10.10.10.100, use the following command in configuration mode (use "conf term" to go to this mode):

ip route 172.16.1.1 255.255.255.255 10.10.10.100

Otoh, if you mean that packets coming *from* 172.16.1.1 should be treated differently, that's a whole other story; then you'ld need to implement policy based routing (pbr). Let me know if you need this.

That is exactly what I tried, but when I enter that I get the message:

%Inconsistent address and mask

And that's it...

any ideas?

thanks

Are you sure it is *exactly* what you tried?

Maybe you made a typo, or used 255.255.255.0 (or other mask) instead of 255.255.255.255 ?

These are really the most probable causes I can think of...

I got the router to work... however... as soon as it reboots the settings are lost. Is there another command I require to save the setting or is there some enabled to stop changes being made?

thanks

Hi,

Change the configuration and save the conf with "wr" command at privileged mode and then reboot.

I'm not sure if this is what you need but try this:

At CLI type : copy running-config startup-config
