Release Information

Statement introduced before JUNOS Release 7.4.

Support for the topology statement introduced in JUNOS Release 9.0.

Support for the realm statement introduced in JUNOS Release 9.2.

Description

Enable OSPF routing on a router interface.

You must include at least one interface statement in the configuration to enable OSPF on the router.

Options

interface-name—Name of the interface. To configure all interfaces, you can specify all. For details about specifying interfaces, see interface naming in the JUNOS Network Interfaces Configuration Guide.
The remaining statements are explained separately.

Usage Guidelines

See Minimum OSPF Configuration, Configuring an Interface on a Broadcast or Point-to-Point Network, Configuring Interface Properties for MT-OSPF, and Configuring Multiple Address Families for OSPFv3.

Required Privilege Level

routing—To view this statement in the configuration.

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