I knew it would not work because the router was telling me exactly what you said.
I just wanted to make sure.
what if I used 192.168.2.8/29 for f0/1 It should work right? Because the address don't fall within the same range.My daily blog about IT and tech stuff

That would be fine. In this case you noticed the problem because you're putting the overlapping ranges onthe same router. It can be very difficult to troubleshoot VLSM if you have overlapping subnets at different points in the network. In that case you won't get an error message from the router, just missing routes.The only easy day was yesterday!
