Ospf Timer Hello - HP 5920 Series Command Reference Manual

Usage guidelines
If an interface receives no hello packet from a neighbor within the dead interval, the interface considers
the neighbor down. The dead interval on an interface is at least four times the hello interval. Routers
attached to the same segment must have the same dead interval.
Examples
# Configure the dead interval for VLAN-interface 10 as 60 seconds.
<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] ospf timer dead 60
