Command Modes
CONFIGURATION
Command
History
fast-convergence
s z
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, enter no fast convergence.
Parameters
Defaults
None.
Command Modes
ROUTER OSPF

History
Usage
Information
The higher this parameter is set, the faster OSPF converge takes place. Note that the faster the
convergence, the more frequent the route calculations and updates. This will impact 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 Networkingtechnical support.
flood-2328
z
Enable RFC-2328 flooding behavior.
Syntax
flood-2328
To disable, use the no flood-2328 command.
Defaults
Disabled
