Configures frequency for monitoring database overflow.
0 seconds. If the device enters OverflowState, you must reboot before the device leaves this state.
OSPF router configuration mode
OSPF router VRF configuration mode
This command specifies how long a device that has entered the OverflowState waits before resuming normal operation of external LSAs. However, if the external link state database (LSDB) is still full, the device lapses back into OverflowState. If the configured value of the database overflow interval is zero, then the device never leaves the database overflow condition.
When the maximum size of the LSDB is reached (this is a configurable value in the external-lsdb-limit CLI), the device enters OverflowState. In this state, the device flushes all non-default AS-external-LSAs that the device had originated. The devie also stops originating any non-default external LSAs. Non-default external LSAs are still accepted if there is space in the database after flushing. If no space exists, the Non-default external LSAs are dropped and not acknowledged.
The no form of the command disables the overflow interval configuration.
The following example configures a database-overflow interval of 60 seconds.
device# configure terminal device(config)# router ospf device(config-router-ospf-vrf-default-vrf)# database-overflow-interval 60
