Fast-Convergence - Dell Z9500 Command Reference Manual

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.

8.3.7.0
7.8.1.0
Usage
The higher this parameter is set, the faster OSPF converge takes place.
Information
Generally, convergence level 1 meets most convergence requirements. Higher
convergence levels should only be selected following consultation with Dell
Networking technical support.
1270
Enter the convergence level desired. The higher this
parameter is set, the faster OSPF converge takes place. The

Introduced on the Z9000.
Introduced on the S4810.
Introduced on all platforms.
