Router ID : A 32-bit integer in dotted decimal format identifying the router, about which information is
displayed. This is a configured value.

OSPF Admin Mode : Shows whether the administrative mode of OSPF in the router is enabled or
disabled. This is a configured value.

ASBR Mode : Indicates whether the ASBR mode is enabled or disabled. Enable implies that the
router is an autonomous system border router. Router automatically becomes an ASBR when it is
configured to redistribute routes learnt from other protocol. The possible values for the ASBR status
is enabled (if the router is configured to re-distribute routes learned by other protocols) or disabled (if
the router is not configured for the same).

RFC 1583 Compatibility : Indicates whether 1583 compatibility is enabled or disabled. This is a
configured value.

External LSDB Limit : The maximum number of non-default AS-external-LSA (link state
advertisement) entries that can be stored in the link-state database.

Exit Overflow Interval : The number of seconds that, after entering overflow state, a router will
attempt to leave overflow state.

Spf Delay Time : The number of seconds between two subsequent changes of LSAs, during which
time the routing table calculation is delayed.

Spf Hold Time: The number of seconds between two consecutive spf calculations.

Opaque Capability: Shows whether the router is capable of sending Opaque LSAs. This is a
configured value.

Autocost Ref BW: Shows the value of auto-cost reference bandwidth configured on the router.

ABR Status: Shows whether the router is an OSPF Area Border Router.

ASBR Status: Reflects whether the ASBR mode is enabled or disabled. Enable implies that the
router is an autonomous system border router. The router automatically becomes an ASBR when it
is configured to redistribute routes learnt from other protocols. The possible values for the ASBR
status is enabled (if the router is configured to redistribute routes learned by other protocols) or
disabled (if the router is not configured for the same).

Stub Router: When OSPF runs out of resources to store the entire link state database, or any other
state information, OSPF goes into stub router mode. As a stub router, OSPF re-originates its own
router LSAs, setting the cost of all non-stub interfaces to infinity. To restore OSPF to normal
operation, disable and re-enable OSPF.

Exit Overflow Interval: The number of seconds that, after entering overflow state, a router will
attempt to leave overflow state.

External LSDB Overflow: When the number of non-default external LSAs exceeds the configured
limit, External LSDB Limit, OSPF goes into LSDB overflow state. In this state, OSPF withdraws all of
its self-originated non-default external LSAs. After the Exit Overflow Interval, OSPF leaves the
overflow state, if the number of external LSAs has been reduced.

External LSA Count: The number of external (LS type 5) link-state advertisements in the link-state
database.

External LSA Checksum: The sum of the LS checksums of external link-state advertisements
contained in the link-state database.

AS_OPAQUE LSA Count: Shows the number of AS Opaque LSAs in the link-state database.

AS_OPAQUE LSA Checksum: Shows the sum of the LS Checksums of AS Opaque LSAs
contained in the link-state database.

New LSAs Originated: The number of new link-state advertisements that have been originated.

LSAs Received: The number of link-state advertisements received determined to be new
instantiations.
