database-overflow-interval (OSPFv3)

Configures frequency for monitoring database overflow.

Syntax

database-overflow-interval interval

no database-overflow-interval

Command Default

10 seconds. If the router enters OverflowState, you must reboot before the router leaves this state.

Parameters

interval: Time interval at which the device checks to see if the overflow condition has been eliminated. Valid values range from 0 through 86400 seconds (24 hours).

Modes

OSPFv3 router configuration mode

OSPFv3 router VRF configuration mode

Usage Guidelines

This command specifies how long after a router that has entered the OverflowState before it can resume normal operation of external LSAs. However, if the external link state database (LSDB) is still full, the router lapses back into OverflowState.

When the maximum size of the LSDB is reached (this is a configurable value in the external-lsdb-limit CLI), the router enters OverflowState. In this state, the router flushes all non-default AS-external-LSAs that the router had originated. The router 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.

Examples

The following example configures a database-overflow interval of 120 seconds.

device# configure terminal
device(config)# ipv6 router ospf
device(config-ipv6-router-ospf-vrf-default-vrf)# database-overflow-interval 120
