13.1.2.22 database-overflow
Use this command to limit the size of OSPF link state database overflow, a condition where the
router is unable to maintain the database in its entirety. Setting database overflow allows you to set
a limit on the number of external LSAs. If the limit is exceeded, self-originated external LSAs will
be removed so that OSPF can handle the large number of external LSAs coming from another
router. When the warning level is set, a Syslog message will be issued when the number of external
LSAs has reached the specified level. Every exit-overflow interval seconds, the database will be
checked and, if the total is less than the limit specified, the self originated external LSAs will be
restored.
database-overflow external {[exit-overflow-interval interval] [limit limit]
[warning-level level]}
Syntax Description
Command Syntax of the “no” Form
The “no” form of this command removes the database overflow limits:
no database-overflow external {[exit-overflow-interval interval] [limit limit]
[warning-level level]}
Command Type
Router command.
Command Mode
Router configuration: Matrix->Router(config-router)#
external Specifies the LSA type as external (Type 5.)
exit-overflow-
interval interval
Specifies an interval (in seconds) the OSPF link state
database will be checked to determine if the overflow limit
has been reached. Valid values are 0 - 86400. Default is 0.
limit limit Specifies the peak number of LSAs accepted before
overflow occurs. Valid values are 0 - 4000. Default is 0.
NOTE: Limit value must be greater than the
warning-level value and set prior to it since all
defaults are 0.
warning-level
level
Specifies the number of LSAs at which a warning of pending
overflow will be generated. Valid values are 0 - 4000.
Default is 0.
