ospf timer retransmit multi-area

Function

The ospf timer retransmit multi-area command configures an LSA retransmission interval on a multi-area adjacency interface.

The undo ospf timer retransmit multi-area command restores the default LSA retransmission interval.

By default, the LSA retransmission interval on multi-area adjacency interfaces is 5s.

Format

ospf timer retransmit interval multi-area { area-id | area-id }

undo ospf timer retransmit multi-area { area-id | area-id }

Parameters

Parameter	Description	Value
interval	Specifies an LSA retransmission interval.	The value is an integer ranging from 1 to 3600, 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

To set up an OSPF neighbor relationship with a neighbor, a device sends an LSA and waits for an LSAck packet from the neighbor. If the device does not receive an LSAck packet within the specified interval, it retransmits the LSA.

The LSA retransmission interval must not be too small; otherwise, unnecessary retransmission occurs.

Prerequisites

The ospf enable multi-area command has been run.

Precautions

The ospf timer retransmit multi-area command does not apply to null interfaces.

Example

# Set the LSA retransmission interval to 8s on multi-area adjacency interface.
