The command output shows "Lost packet ratio is 100%", indicating that the link is faulty.

The static route is associated with the NQA test instance on Router B. After detecting a link
fault, NQA rapidly notifies Router B that the associated static route is unavailable. Router A
cannot learn the route to 2001:db8:7::/64 from Router B. However, Router A can learn the route
to 2001:db8:7::/64 from Router C. The outbound interface to 2001:db8:7::/64 is changed to GE
2/0/0 and the cost is 20. Traffic will be switched to Router C→Switch B.
