OVERFLOW DATABASE EXTERNAL

Syntax

overflow database external MAXDBSIZE <0-2147483647>
WAITTIME <0-65535>

no overflow database external

Parameters

MAXDBSIZE Specifies

the maximum size of an external database.

Note that this value should be the same on all routers in
the Autonomous System

(

AS). Choose a value between

0 and 2,147,483,647.

WAITTIME

Specifies the number of seconds the router waits before

trying to exit the database overflow state. Choose a
value between 0 and 65,535. If this parameter is 0, the
router exits the overflow state only after an explicit
administrator command.

Description

Use the OVERFLOW DATABASE command to configure the size of the
external database and the time the router waits before it tries to exit the
overflow state.

Use this command to limit the number of AS-external-LSAs a router can
receive when it is in the wait state. It takes the number of seconds
specified by the WAITTIME parameter to recover from this state.

Use the no form of this command to reset it to its default value.

Command Mode

Router mode

Example

The following example sets the size of the database overflow to 5 and the
time to recover from the overflow state to 3 seconds:

switch#configure terminal

switch(config)#router ospf 100

switch(config-router)# overflow database external 5 3
