Quidway S8500 Series Routing Switches Chapter 3 OSPF Configuration Commands
Huawei Technologies Proprietary

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 p2p and broadcast interfaces are
40 seconds, and that for those of p2mp and nbma interfaces is 120 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.
Example
# Set the peer dead timer on the interface Vlan-interface 10 to 80 seconds.
[Quidway] interface Vlan-interface 10
[Quidway-Vlan-interface10] ospf timer dead 80
# Configure the number of Hello packets sent on the port Vlan-interface 10 within three
seconds.
[Quidway] interface Vlan-interface 10
