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.

Description Use the
ospf timer hello command to set the hello interval on an interface.
Use the
undo ospf timer hello command to restore the default hello interval on
an interface.
The hello interval defaults to 10s for P2P and Broadcast interfaces, and defaults to
30s for P2MP and NBMA interfaces.
The shorter the hello interval is, the faster the topology converges and the more
resources are consumed. Make sure the hello interval on two neighboring
interfaces is the same.
This configuration is not supported on the NULL interface.

Examples # Configure the hello interval on the current interface as 20 seconds.
