seconds: Dead interval of the OSPF neighbor. It is in seconds and ranges from 1 to
65,535.
minimal : Specifies the port to run Fast Hello function.
multi-hello : Sends multiple hello packets.
packets : Number of Hello packets sent within one second.
Description
Use the ospf timer dead command to configure the dead interval of the OSPF
peer. Use the undo ospf timer dead command to restore the default value of the
dead interval of the peer.
By default, the dead interval for the OSPF peers of broadcast interfaces are 40
seconds.
The dead of OSPF peers means that within this interval, if no Hello packet is
received from the peer, the peer will be considered to be invalid. The value of
dead seconds should be at least four times that of the Hello seconds . The dead
seconds for the routers on the same network segment must be identical.
Related command: ospf timer hello .
Use the ospf timer dead minimal multi-hello packets command to set Fast
Hello function on the port. The fixed dead interval is 1. The packets argument is
the specified number of sent Hello packets.
