A route filter is a configuration mechanism used in Junos OS, the operating system for Juniper Networks devices. It is used to control the flow of routing updates by filtering which routes are allowed to be advertised or accepted by a routing protocol.
A route filter can be defined as either a list of prefixes or a single prefix. The prefixes that are listed in a route filter can be configured separately and then referenced in a routing policy.
Answer A is incorrect because it refers to "a list of prefixes" but does not specify whether it is a route filter or some other type of list.
Answer B is incorrect because it describes a single prefix that is configured separately but does not specify whether it is part of a route filter or a different type of configuration.
Answer C is the correct answer because it describes a route filter as "a list of prefixes that is configured separately and can be referenced in a policy."
Answer D is incorrect because it describes a single prefix that can be configured within a policy, but does not specify whether it is part of a route filter or a different type of configuration.
In summary, a route filter is a list of prefixes that is configured separately and can be referenced in a policy to control the flow of routing updates.
