Description

Configure the local routing device so that it appears to be overloaded. You might do this when you want the routing device to participate in OSPF routing, but do not want it to be used for transit traffic.

Note:

Traffic destined to directly attached interfaces continues to reach the routing device.

Options

timeout seconds—(Optional) Number of seconds at which the overloading is reset. If no timeout interval is specified, the routing device remains in overload state until the overload statement is deleted or a timeout is set.

  • Range: 60 through 1800 seconds

  • Default: 0 seconds

The timeout is configured with a prefix-limit. If the number of prefixes exceeds the configured limit, the overload state is reached. The routing device remains in the overload state even though the prefixes have been reduced under the limit. Therefore, you need to clear the overload state using the clear (ospf | ospf3) overload command.

Note:

Multitopology Routing does not support the timeout option.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.

Release Information

Statement introduced before Junos OS Release 7.4.

Support for Multitopology Routing introduced in Junos OS Release 9.0.

Support for Multitopology Routing introduced in Junos OS Release 9.0 for EX Series switches.

Support for the realm statement introduced in Junos OS Release 9.2.

Support for the realm statement introduced in Junos OS Release 9.2 for EX Series switches.
