Figure 6-58 OSPFv2 Interface Settings (Show Detail) Window The fields that can be configured are described below: Parameter Cost Hello Interval Dead Interval Priority 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. By default, this value is 1. Select the Default option to use the default value. 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 hellointerval 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. 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. 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 become the DR, the router with the higher router priority will be elected the DR. If the routers have the same priority, the router with the higher router ID takes precedence. Only routers with non-zero router priority values are eligible to become the DR or Backup Designated Router (BDR). By default, this value is 1. 267
