The fields that can be configured are described below:
Parameter Description
Cost
Enter the cost value here. The range is from 1 to 65535. The interface cost reflects
the overhead for sending the packet across the interface. This cost is advertised
as the link cost in the router link advertisement. By default, this value is 1.
Select the Default option to use the default value.
Hello Interval
Enter the Hello Interval time value here. The range is from 1 to 65535 seconds.
The Hello Interval is advertised in the hello packets. Configure the same hello-
interval for all routers on a specific network. A shorter Hello Interval ensures faster
detection of topological changes but generates more routing traffic and might
cause routing instability. By default, this value is 10 seconds.
Select the Default option to use the default value.
Dead Interval
Enter the Dead Interval time value here. The range is from 1 to 65535 seconds.
The Dead Interval is the amount of time that the router waits to receive an OSPF
hello packet from the neighbor before declaring the neighbor down. This value is
advertised in the router's hello packets. It must be the same for all routers on a
specific network. A smaller dead interval will ensure faster topology change
detection but might cause routing instability. By default, this value is 40 seconds.
Select the Default option to use the default value.
Priority
Enter the priority value here. The range is from 0 to 255. The OSPF router will
determine a Designated Router (DR) for the multi-access network. This sets the
priority used to determine the OSPF DR for a network. If two routers attempt to
