When a floating static route is configured, which action ensures that the backup route is used when the primary route fails?
Click on the arrows to vote for the correct answerA. B. C. D.
When configuring a floating static route, it is used as a backup route that only becomes active when the primary route fails. This allows network administrators to provide redundancy in case of network failures.
Administrative distance is a metric used by routers to determine the trustworthiness of routing information from different sources. It is a value assigned to a particular routing protocol, and the lower the administrative distance, the more reliable the protocol.
When configuring a floating static route, the administrative distance must be configured to be higher than that of the primary route. This is because routers prefer routes with lower administrative distances, and by configuring the floating static route with a higher administrative distance, it will only become active when the primary route fails. Therefore, answer D is incorrect.
The default-information originate command is used to redistribute a default route into a routing protocol. It is not directly related to the configuration of a floating static route. Therefore, answer B is incorrect.
Answer C is the correct choice. By configuring the floating static route with a lower administrative distance than the primary route, it will be preferred as the primary route until the primary route fails, at which point the floating static route will become active.
In summary, when configuring a floating static route, ensure that it has a lower administrative distance than the primary route so that it is used as a backup.
