The correct answer is D. Change the route preference on OSPF external routes. Arranging metric on the backup link will not work. Route preferrance of OSPF is 150. BGP is 170. Router will never choose to route traffic as soon as OSPF route is up. Route preference should be lowered for BGP or increased for OSPF external routes.
Question
Click the Exhibit button. Site HQ connects to Site A through a provider using BGP. The BGP route for Site A destinations is redistributed info OSPF within site HQ. You provision a backup link over a dedicated leased line that connects to Site A, which should only be used when Site A is not reachable through the provider. When the backup circuit is provisioned, traffic destined to Site A transits the backup link instead of the provider link. Referring to the exhibit, how do you solve this problem?
