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 LSAs in the link state database.
External LSA Checksum - The sum of the LS checksums of the external LSAs in the link-state
database. This sum can be used to determine if there has been a change in a router's link state
database, and to compare the link-state databases of two routers. This value is in hexadecimal.
AS_OPAQUE LSA Count - The number of opaque LSAs with domain wide flooding scope.
AS_OPAQUE LSA Checksum - The sum of the LS checksums of the opaque LSAs with domain
wide flooding scope. This sum can be used to determine if there has been a change in a router's link
state database, and to compare the link-state databases of two routers. This value is in hexadecimal.
New LSAs Originated - The number of LSAs originated by this router.
LSAs Received - The number of LSAs received.
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.
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.
