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.
