Release Information
Command introduced in Junos OS Release 7.4.
Command introduced in Junos OS Release 9.0 for EX Series switches.
realm option introduced in Junos OS Release 9.2.
Database protection introduced in Junos 10.2.

Description
Display Open Shortest Path First (OSPF) overview information.
Options
none | — | Display standard information about all OSPF neighbors for all routing instances. |
brief | extensive | — | (Optional) Display the specified level of output. |
instance instance-name | — | (Optional) Display all OSPF interfaces under the named routing instance. |
logical-system (all | logical-system-name) | — | (Optional) Perform this operation on all logical systems or on a particular logical system. |
realm (ipv4-multicast | ipv4-unicast | ipv6-multicast) | — | (Optional) (OSPFv3 only) Display information about the specified OSPFv3 realm, or address family. Use the realm option to specify an address family for OSPFv3 other than IPv6 unicast, which is the default. |

Output Fields
Table 1 lists the output fields for the show ospf overview command. Output fields are listed in the approximate order in which they appear.
Table 1: show ospf overview Output Fields
Field name | Field Description | Level of Output |
---|---|---|
Instance | OSPF routing instance. | All levels |
Router ID | Router ID of the routing device. | All levels |
Route table index | Route table index. | All levels |
Configured overload | Overload capability is enabled. If the overload timer is also configured, display the time that remains before it is set to expire. This field is not displayed after the timer expires. | All levels |
Toplogy | Topology identifier. | All levels |
Prefix export count | Number of prefixes exported into OSPF. | All levels |
Full SPF runs | Number of complete Shortest Path First calculations. | All levels |
SPF delay | Delay before performing consecutive Shortest Path First calculations. | All levels |
SPF holddown | Delay before performing additional Shortest Path First (SPF) calculations after the maximum number of consecutive SPF calculations is reached. | All levels |
SPF rapid runs | Maximum number of Shortest Path First calculations that can be performed in succession before the hold-down timer begins. | All levels |
LSA refresh time | Refresh period for link-state advertisement (in minutes). | All levels |
Database protection state | Current state of database protection. | All levels |
Warning threshold | Threshold at which a warning message is logged (percentage of maximum LSA count). | All levels |
Non self-generated LSAs | Number of LSAs whose router ID is not equal to the local router ID: Current, Warning (threshold), and Allowed. | All levels |
Ignore time | How long the database has been in the ignore state. | All levels |
Reset time | How long the database must stay out of the ignore or isolated state before it returns to normal operations. | All levels |
Ignore count | Number of times the database has been in the ignore state: Current and Allowed. | All levels |
Restart | Graceful restart capability: enabled or disabled. | All levels |
Restart duration | Time period for complete reacquisition of OSPF neighbors. | All levels |
Restart grace period | Time period for which the neighbors should consider the restarting routing device as part of the topology. | All levels |
Graceful restart helper mode | (OSPFv2) Standard graceful restart helper capability (based on RFC 3623): enabled or disabled. | All levels |
Restart-signaling helper mode | (OSPFv2) Restart signaling-based graceful restart helper capability (based on RFC 4811, RFC 4812, and RFC 4813): enabled or disabled. | All levels |
Helper mode | (OSPFv3) Graceful restart helper capability: enabled or disabled. | All levels |
Trace options | OSPF-specific trace options. | extensive |
Trace file | Name of the file to receive the output of the tracing operation. | extensive |
Area | Area number. Area 0.0.0.0 is the backbone area. | All levels |
Stub type | Stub type of area: Normal Stub, Not Stub, or Not so Stubby Stub. | All levels |
Authentication Type | Type of authentication: None, Password, or MD5. Note: The Authentication Type field refers to the authentication configured at the [edit protocols ospf area area-id] level. Any authentication configured for an interface in this area will not affect the value of this field. | All levels |
Area border routers | Number of area border routers. | All levels |
Neighbors | Number of autonomous system boundary routers. | All levels |
