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.
S3048–ON
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

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.
