Version 8.3.11.1
Version 7.5.1.0
pre-Version
6.1.1.1

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.
C-Series, E-Series, S-Series, Z-Series, S4810
Syntax fast-convergence {number}
To cancel fast-convergence, use the no fast convergence command.
Parameters
number
Defaults none.
Command Modes ROUTER OSPF
Command History
Version 8.3.11.1
Version 8.3.7.0
Version 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 Force10 technical support.

flood-2328

Enable RFC-2328 flooding behavior.
C-Series, E-Series, S-Series, Z-Series, S4810
Syntax flood-2328
To disable, use the no flood-2328 command.
Defaults Disabled.
Command Modes ROUTER OSPF
Introduced on the Z9000.
Introduced on the C-Series.
Introduced on the E-Series.
Enter the convergence level desired. The higher this parameter is set,
the faster OSPF converge takes place. The range is 1 to 4.
Introduced on the Z9000.
Introduced on the S4810.
Introduced on all platforms.
NOTE: The faster the convergence, the more frequent the route calculations and updates.
This impacts CPU utilization and may impact adjacency stability in larger topologies.
