Routing Protocol Configuration Command Set
Configuring OSPF
13.2.3.22 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.

Specifies the LSA type as external (Type 5.)
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.
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.
Specifies the number of LSAs at which a warning of
pending overflow will be generated. Valid values are 0 -
4000. Default is 0.
