Service Manual

Version Description
7.5.1.0 Introduced on the C-Series.
pre- 6.1.1.1 Introduced on the E-Series.
Usage Information The distribute-list out command applies to routes autonomous system 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.
S3048–ON
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

Version Description
9.8(0.0) Introduced on the S3048-ON and S4048-ON.
9.7(0.0) Introduced on the S6000-ON.
9.0.2.0 Introduced on the S6000.
8.3.19.0 Introduced on the S4820T.
8.3.11.1 Introduced on the Z9000.
8.3.7.0 Introduced on the S4810.
7.8.1.0 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.
