Question Image

Refer to the exhibit. A company is configuring a failover plan and must implement the default routes so that a floating static route takes over traffic forwarding when the primary link fails.

Which primary route configuration must be used?

  • A ip route 0.0.0.0 0.0.0.0 192.168.0.2
  • B ip route 0.0.0.0 0.0.0.0 192.168.0.2 GigabitEthernet1/0
  • C ip route 0.0.0.0 0.0.0.0 192.168.0.2 floating
  • D ip route 0.0.0.0 0.0.0.0 192.168.0.2 tracked
Explanation

A primary static default route must be installed with the normal static-route administrative distance so it is preferred over the backup. A floating static route is the secondary route and is made to "float" by assigning it a higher administrative distance than the primary route. The standard primary default route in this case is ip route 0.0.0.0 0.0.0.0 192.168.0.2. Cisco documentation states that static routes have a default administrative distance of 1, and a floating static route is configured with a higher administrative distance for backup use. (cisco.com)
