Description
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. The cost is inversely
proportional to the speed of an interface. The cost can be either manually
assigned or be automatically determined. By default, the cost of an interface is
calculated based on reference bandwidth. The cost corresponds to a reference
bandwidth of 1. Select the Default option to use the default value which is 1.
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. Select the Default option to use the default value which
is 10 seconds.
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. Specifying a smaller Dead Interval ensures faster detection of
topology changes, but might cause routing instability. Select the Default option to
use the default value which is 40 seconds.
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
