Aren't > you generating default from the Internet gateways? On switch 3550-02 the default route of 0.0.0.0 0.0.0.0 10.50.2.24 is pointing to switch 3550-24. The default route on that switch is 0.0.0.0 0.0.0.0 10.50.1.20 which is 3560-20 and then it hits the router. So locations 2960-14 & 2960-07 are getting there internet from Internet west because of the default routes. What I want to do is have location 2960-07 get its internet from Internet east.

Would you have an example of this?
