fast-convergence

This command sets the minimum LSA origination and arrival times to zero (0), allowing more rapid route computation so that convergence takes less time.

Syntax

fast-convergence { number}

To cancel fast-convergence, use the no fast convergence command.

Parameters

number

Enter the convergence level desired. The higher this parameter is set, the faster OSPF converge takes place. The range is from 1 to 4.

Defaults

none.

Command Modes

ROUTER OSPF

Supported Modes

Full—Switch

Command History

Version	Description
9.9(0.0)	Introduced on the FN IOM.
8.3.16.1	Introduced on the MXL 10/40GbE Switch IO Module.

Usage Information

The higher this parameter is set, the faster OSPF converge takes place.

NOTE: The faster the convergence, the more frequent the route calculations and updates. This behavior impacts CPU utilization and may impact adjacency stability in larger topologies.

Generally, convergence level 1 meets most convergence requirements. Higher convergence levels should only be selected following consultation with Dell Networking technical support.
