IP Connectivity

When a floating static route is configured, which action ensures that the backup route is used when the primary route fails?

  • A The administrative distance must be higher on the primary route so that the backup route becomes secondary.
  • B The default-information originate command must be configured for the route to be installed into the routing table.
  • C The floating static route must have a lower administrative distance than the primary route so it is used as a backup.
  • D The floating static route must have a higher administrative distance than the primary route so it is used as a backup
Explanation

A floating static route works as a backup only when it is assigned a higher administrative distance than the primary route. The router prefers the route with the lower administrative distance while it is available; if the primary route is lost, the higher-distance static route is then installed and used as the fallback path.
