Fast-Convergence - Dell S6000 Reference Manual

Version 7.5.1.0
pre-Version
6.1.1.1
Usage The distribute-list out command applies to routes autonomous system
Information boundary routers (ASBRs) redistributes into OSPF. It can be applied to external type
2 and external type 1 routes, but not to intra-area and inter-area routes.

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.

Usage
The higher this parameter is set, the faster OSPF converge takes place.
Information
Open Shortest Path First (OSPFv2 and OSPFv3)
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 from 1 to 4.
Introduced on the S6000.
Introduced on the S4820T.
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 behavior impacts CPU utilization and may impact adjacency
stability in larger topologies.
