User’s Guide 700/1523
Default Metric:
Default value for redistributed routes.
Network Area:
Shows area for the Network Area setting.
Default Route Advertise:
Indicates whether the default routes received from other source protocols
are advertised or not.
Always:
Shows whether default routes are always advertised.
Metric:
The metric of the routes being redistributed. If the metric is not configured, this field is blank.
Metric Type:
Shows whether the routes are External Type 1 or External Type 2.
Number of Active
Areas:
The number of active OSPF areas. An “active” OSPF area is an area with at least one
interface up.
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.
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.
LSA Count:
The total number of link state advertisements currently in the link state database.
Maximum Number of LSAs:
The maximum number of LSAs that OSPF can store.
LSA High Water Mark:
The maximum size of the link state database since the system started.
AS Scope LSA Flood List Length:
Length of global flood list for LSAs with AS scope.
Retransmit List Entries:
The total number of LSAs waiting to be acknowledged by all neighbors. An
LSA may be pending acknowledgment from more than one neighbor.
Maximum Number of Retransmit Entries:
The maximum number of LSAs that can be waiting for
acknowledgment at any given time.
Retransmit Entries High Water Mark:
The highest number of LSAs that have been waiting for
acknowledgment.
NSF Helper Support:
Configure graceful restart.
NSF Helper Strict LSA Checking:
Terminate graceful restart helper on topology change.
