Setting the Dead Time of an OSPF Neighbor

If no Hello packet is received from a neighbor within a dead interval, the neighbor is considered Down.

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The OSPF interface view is displayed.
Run ospf timer dead interval
The dead time is set for the neighbor relationship.

If the dead interval of an OSPF neighbor is shorter than 10s, the session may be closed. Therefore, if dead interval is shorter than 10s, the actual dead interval of an OSPF neighbor is not shorter than 10s. If the conservative mode is configured using the ospf timer hello command, the configured dead timer takes effect even when its value is less than 10s.

Both the Hello timer and Dead timer are restored to the default values if the network type is changed.
