ospf trans-delay

Function

The ospf trans-delay command adds a transmission delay to LSAs before they are sent by an interface.

The undo ospf trans-delay command restores the default transmission delay of LSAs on an interface.

By default, the transmission delay is 1 second.

Format

ospf trans-delay interval

undo ospf trans-delay

Parameters

Parameter	Description	Value
interval	Specifies a transmission delay to be added to LSAs before they are sent by an interface.	The value is an integer ranging from 1 to 500, in seconds.

Usage Guidelines

Usage Scenario

LSAs age (increase by 1 each second) in LSDBs but do not age during transmission in the network. To ensure that the aging time of LSAs transmitted to the remote device is correct, run the ospf trans-delay command to add a transmission delay to LSAs before they are sent by a local interface. This configuration is especially important to low-speed networks.

Precautions

OSPF does not support the configuration on a null interface.
