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?
