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.

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.
