2811 ROUTERS and adding routing information. How to

[dschneidermars1]

I am looking for some guidance. I do not know what to do in this situation and how to do it. I need to route traffic internally going to 10.x.x.x to two external ip addresses and subnets. Anyone have any step buy step configuration methods on how to do this? I have cisco 2811 devices

Okay you added this route to your router -

172.16.24.0 255.255.248.0 10.0.0.243 

this covers 172.16.28.2 so I can't see what else you can do on the router.

Can you post a "sh ip route" from your router ?

And what is the subnet mask for 10.0.0.58 and 10.0.0.243 ?

Jon

[dschneidermars1]

correct I added that to the router. And the mask for 10.0.0.243 and 58 is 255.255.255.0

You have entered the static incorrectly. You have put -

ip route 172.16.24.0 255.255.255.248 10.0.0.243

and it should be -

ip route 172.16.24.0 255.255.248.0 10.0.0.243

notice the difference in the subnet mask.

Great that worked.

I have branch offices that I added those routes to as well.

I did a tracert at a branch office to 172.16.24.2

and the tracert reaches the main office then the vpn interface of 243 and stops there. Any ideas?

[Jon Marshall]

The traceroute might well stop at the VPN device depending on how the vendor has configured it.

If it is still not working then it is time to go back to the vendor because your routing is working now.

We added this route to the routers

route ip 172.16.24.0 255.255.248.0 10.0.100.10

route ip 192.168.244.0 255.255.255.0 10.0.100.100

I wanted to add an alternative route to those routers in case something happen to our production line. I want to add these routes below. How can I do this in case those primary lines go down.

a.route ip 172.16.24.0 255.255.248.0 10.0.1.243

b.route ip 192.168.224.0 255.255.255.0 10.0.1.243
