Configure route metrics
You can set route metric settings to override the order in which the routes are searched. The router
always uses routes with lower metric numbers in preference to routes with higher metric numbers,
even if the routes with higher metric numbers appear first in the routing table.
To configure route metrics, use the following route parameters:
n Connected Metric: The metric for a route when its interface is active.
n Disconnected Metric: The metric for a route when its interface is inactive.
Normally, both values should be the same, but in some advanced routing scenarios, it is necessary to
use different values.
You can alter route metrics automatically according to various circumstances. This allows for
automatic backup connection paths.
You can put routes and interfaces out of service. Whenever an interface is out of service (OOS), any
route pointing at the interface is also out of service. Whenever a route is out of service, the metric
value is set to 16 in TransPort routing mode and 17 in CIDR mode.
