Description

Configure statically configured routes to be deleted from or retained in the forwarding table when the routing protocol process shuts down normally:

Default

Statically configured routes are deleted from the forwarding table when the routing protocol process shuts down normally. Doing this greatly reduces the time required to restart a system that has a large number of routes in its routing table.

Options

no-retain

Delete statically configured routes from the forwarding table when the routing protocol process shuts down normally. To explicitly specify that routes be deleted from the forwarding table, include the no-retain statement. Include this statement when configuring an individual route in the route portion of the static statement to override a retain option specified in the defaults portion of the statement.

retain

Have a static route remain in the forwarding table when the routing protocol process shuts down normally. Doing this greatly reduces the time required to restart a system that has a large number of routes in its routing table.

Required Privilege Level
