Use this command to set the number of seconds a router must wait to receive a hello packet from its neighbor before determining that the neighbor is out of service.
| seconds | Specifies the number of seconds that a router must wait to receive a hello packet. This parameter is an unsigned integer ranging from 1 to 65535. Default: 40 Seconds. |
| minimal | Sets the dead-interval to 1 second for fast hello. |
| hello-multiplier number | (Optional) Specifies the number of hello-packets that will be sent in 1 second. |
If no parameter is specified, default values are assigned.
Configuration command, Interface configuration.
Dead interval must be the same on neighboring routers (on a specific subnet), but can vary between subnets.
The “no” form of this command sets the dead interval value to the default.
This example shows how to set the dead interval to 20 for VLAN 1:
System(rw-config)->interface vlan 1 System(rw-config-intf-vlan.0.1)->ip ospf dead-interval 20
