3.1.45 ospf timer dead
Syntax
ospf timer dead seconds
undo ospf timer dead
View
Interface view
Parameters
seconds: Dead interval in seconds, in the range 1 to 2147483647.
Description
Use the ospf timer dead command to set the dead interval.
Use the undo ospf timer dead command to restore the default.
The dead interval defaults to 40s for Broadcast, P2P interfaces and defaults to 120s for
P2MP and NBMA interfaces.
If an interface receives no hello packet from the 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. Any two routers attached to the same segment must have the
same dead interval.
This configuration is not supported on the NULL interface.
Related commands: ospf timer hello.
Examples
# Configure the dead interval on the current interface as 60 seconds.
<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] ospf timer dead 60
