Setting the Dead Time of the Neighbor Relationship
Procedure
- 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 after which the neighbor relationship between two routers is set.
By default, the dead time of the neighbor relationship on a P2P or broadcast interface is 40s; the dead time of the neighbor relationship on a P2MP or NBMA interface is 120s; the dead time of the neighbor relationship on the same interface is four times the interval for sending Hello packets.
Setting the dead interval of an OSPF neighbor to longer than 20s is recommended. If the dead interval of an OSPF neighbor is shorter than 20s, the session may be closed.
Both the Hello timer and the Dead timer are restored to their respective default values upon a change to the network type.
