ospf trans-delay multi-area

Function

The ospf trans-delay multi-area command configures an LSA transmission delay on a multi-area adjacency interface.

The undo ospf trans-delay multi-area command restores the default LSA transmission delay.

By default, the LSA transmission delay on multi-area adjacency interfaces is 1s.

Format

ospf trans-delay delayValue multi-area { area-id | area-id }

undo ospf trans-delay multi-area { area-id | area-id }

Parameters

Parameter	Description	Value
delayValue	Specifies an LSA transmission delay.	The value is an integer ranging from 1 to 500, in seconds.
area-id	Specifies the ID of an OSPF area.	The value can be a decimal integer ranging from 0 to 4294967295 or in the format of an IP address.

Usage Guidelines

Usage Scenario

The aging time of each LSA in the LSDB increases by one every second, but LSAs do not age during transmission. To configure an LSA transmission delay on a multi-area adjacency interface so that an extension period (the configured delay) is added to the LSAs to be sent, run the ospf trans-delay multi-area command. This configuration is extremely important on low-speed networks.

Prerequisites

The ospf enable multi-area command has been run.

Precautions

The ospf trans-delay multi-area command does not apply to null interfaces.

Example

# Set the LSA transmission delay on multi-area adjacency interface to 3s.
