The following fields are shown in the OSPF general status display:

CLI display of OSPF general information

Field

Content

OSPF protocol

Whether OSPF is currently enabled.

Router ID

Router ID that this routing switch is currently using to identify itself.

RFC 1583 compatibility

Whether the routing switch is currently using RFC 1583 (compatible) or RFC 2328 (non-compatible rules for calculating external routes.

Intra-area distance

Administrative distance for routes within OSPF areas.

Inter-area distance

Administrative distance for routes between areas within the same OSPF domain.

AS-external

Administrative distance for routes between the OSPF domain and other, Exterior Gateway Protocol domains.

Default import metric

Default metric that will be used for any routes redistributed into OSPF by this routing switch

Default import metric type

Metric type (type 1 or type 2) that will be used for any routes redistributed into OSPF by this routing switch.

Area Border

Whether this routing switch is currently acting as an area border router.

AS Border

Whether this routing switch is currently acting as an AS border router (redistributing routes.)

External LSA Count

Total number of external LSAs currently in the routing switch's link state database.

External LSA Checksum Sum

Sum of the checksums of all external LSAs currently in the routing switch's link state database (quick check for whether database is in sync with other routers in the routing domain.)

Originate New LSA Count

Count of the number of times this switch has originated a new LSA.

Receive New LSA Count

Count of the number of times this switch has received a new LSA.

Graceful Restart Interval

Maximum seconds between graceful restarts.

Graceful Restart Strict-Lsa Checking

Whether LSA checking is enabled or disabled (terminates graceful restart when a change to an LSA would cause flooding during the restart.)

Nonstop forwarding

Whether nonstop forwarding (NSF) is enabled or disabled.

Log Neighbor Adjacency Changes

Whether changes in adjacent neighbors are logged.
