Open Shortest Path First (OSPFv2 and OSPFv3) | 709
Command
History
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.
enable inverse mask
c e
FTOS, by default, permits the user to input OSPF network command with a net-mask. This command
provides a choice between inverse-mask or net-mask (the default).
Syntax
enable inverse mask
To return to the default net-mask, enter no enable inverse mask.
Defaults
net-mask

CONFIGURATION
Command
History
fast-convergence
c e s
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.
