Field Reference
Configuring Static Routes
A static route is a specific path to a particular destination network that is manually defined on the current
device. Static routes are used in a variety of situations, and can be a quick and effective way to route data
from one network to another when there is no dynamic route to the destination, or when use of a dynamic
routing protocol is not feasible.
All routes have a value or “metric” that represents its priority of use. (This metric is also referred to as
“administrative distance.”) When two or more routes to the same destination are available, devices use
administrative distance to decide which route to use.
For static routes, the default metric value is one, which gives them precedence over routes from dynamic
routing protocols. If you increase the metric to a value greater than that of a dynamic route, the static
route operates as a back-up in the event that dynamic routing fails. For example, Open Shortest Path First
