Dell C1048P Port Extender Networking Command-Line Reference Guide for the C900 - Page 1251

Version 8.3.7.1 7.5.1.0 6.1.1.1 Description Introduced on the S4810. Introduced on the C-Series. Introduced on the E-Series. 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. C9000 Series 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 Command History This guide is platform-specific. For command information about other platforms, see the relevant Dell Networking OS Command Line Reference Guide. The following is a list of the Dell Networking OS version history for this command. Version 9.9(0.0) 9.2(1.0) 8.3.19.0 8.3.11.1 8.3.7.0 7.8.1.0 Description Introduced on the C9010. Introduced on the Z9500. Introduced on the S4820T. Introduced on the Z9000. Introduced on the S4810. Introduced on all platforms. 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.
