Usage
Information
The distribute-list out command applies to routes being redistributed by autonomous system boundary
routers (ASBRs) 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-converge
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-converge {number}
To cancel fast-convergence, use the no fast converge command.
Parameters
Defaults
none
Command Modes
ROUTER OSPF
Command
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 Force10 Technical Support.
flood-2328
Enable RFC-2328 flooding behavior.
Syntax
flood-2328
To disable, use the no flood-2328 command.
Defaults
Disabled
Command Modes
ROUTER OSPF
Command
History
Usage
Information
In OSPF, flooding is the most resource-consuming task. The flooding algorithm, described in
RFC-2328, requires that OSPF flood LSAs (Link State Advertisements) on all interfaces, as governed
by LSAs flooding scope (see Section 13 of the RFC). When multiple direct links connect two routers,
the RFC-2328 flooding algorithm generates significant redundant information across all links.
number
Enter the convergence level desired. The higher this parameter is set, the
faster OSPF converge takes place.
