Configuring OSPF
To configure OSPF version 2 (usually referred to simply as OSPF), you include the following statements:
protocols {ospf {disable;export [ policy-names ];external-preference preference;graceful-restart {disable;helper-disable;notify-duration seconds;restart-duration seconds;}import [ policy-names ];no-nssa-abr;no-rfc-1583;overload {timeout seconds;}preference preference;prefix-export-limit;rib-group group-name;reference-bandwidth reference-bandwidth;sham-link {local address;}spf-options {delay milliseconds;rapid-runs number;holddown milliseconds;}traffic-engineering {advertise-unnumbered-interfaces;multicast-rpf-routes;no-topology;shortcuts {ignore-lsp-metrics;lsp-metric-into-summary;}}traceoptions {file filename <files number> <size size> <world-readable |

To configure OSPF version 3 (OSPFv3), you include the following statements:
protocols {ospf3 {disable;export [ policy-names ];external-preference preference;graceful-restart {disable;helper-disable;notify-duration seconds;restart-duration seconds;}import [ policy-names ];overload {timeout seconds;}preference preference;prefix-export-limit;reference-bandwidth reference-bandwidth;realm (ipv4-unicast | ipv4-multicast | ipv6-multicast);rib-group group-name;spf-options {delay milliseconds;holddown milliseconds;rapid-runs number;}traceoptions {file filename <files number> <size size> <world-readable |
no-world-readable>;flag flag <flag-modifier> <disable>;}area area-id {area-range network/mask-length <restrict>

For a list of hierarchy levels at which you can include these statements, see the statement summary sections for these statements.
For a detailed OSPFv3 example configuration, see the Junos Feature Guide.
By default, OSPFv2 and OSPFv3 are disabled.
 | Note: In this manual, the term OSPF refers to both OSPFv2 and OSPFv3. |
