Hi Jacob, A does not connect to C. In the given example, the desired result is that traffic does not flow from C to A *at all*. The permissible traffic flows are: WA WB WBC AB CB These traffic flows do not occur: ABC (A lacks a route for C) W->A->B->C (A lacks a route for C) This traffic flow is intended to fail but doesn't because of W's more-specifics: C->B->A->W Regards, Bill Herrin -- William D.
