How to specify a route on a port when the route overlaps with an internal vlan.
Hi,
I need to define/specify a route on my 3560 Catalyst. FE0/1 connects to a router which should be the target for any 10.x.x.x traffic (other than the subnet which has been allocated for my internal use(10.25.x.x)).
I have specified the internal network 10.25.x.x as vlan25.
How can I specify that FE0/1is the route for the 10.x.x.x network without getting messages that vlan25 overlaps with the 10 network I want to route to??
The switch is configured for classless routing - a default router is specified for the rest of my (off network) routing.

And be sure you have "ip classless" and "no auto-summary" commands in. This will allow for VLSM and wont summarize your 10.x.x.x networks into a single class A subnet.

Hi,
The company we link to uses has a class A 10.0.0.0 255.0.0.0 network - I have been allocated 10.25.0.0 255.255.0.0 for my internal use / further subnetting.
I can see the overlap but do not know how to address the issue.

My problem turned out to be a fundamental understanding of how routing works. I was indeed wrong to specify a rote to a network on which I was a part. By using additional subnets I was able to resolve the overlap and specify valid routes.

Thank you for trying with a badly composed question.
