Hi All,

Just playing about with setting up OSPF in packet tracer to understand how it works but running into an issue with just setting up the bliming interface!!

Currently have one site setup with the router running 4 vlans over 6 switches and 10 PCs. I have had no issues with this and works as expected. My issue is when I came to setting up multiple sites to begin to route between each other that I added an extra module to each router so I had enough interfaces for the job.

Below is a screen shot of the current setup;

I have gone to Router 3 and want to set an ip of 172.16.10.1 to interface fa0/0/0, once I go to the CLI and go through "en","conf t","int fa0/0/0" I then put in the below and get this result.

I have looked through everywhere and cannot find the solution, I know this will be an easy I hope!!

Cheers
