15.18 ip ospf dead-interval
To set the interval during which at least one hello packet must be received from a neighbor before the
router declares that neighbor down, use the ip ospf dead-interval command in interface configuration
mode. To restore the default value, use the no form of this command.
Command Syntax
ip ospf dead-interval seconds
no ip ospf dead-interval
seconds Interval (in seconds) during which the router must receive at least one hello packet
from a neighbor or else that neighbor is removed from the peer list and does not
participate in routing. The range is 1 to 65535. The value must be the same for all
nodes on the network.
Default
seconds: Four times the interval set by the ip ospf hello-interval command.
Command Mode
Interface configuration
Usage
The dead interval is advertised in OSPF hello packets. This value must be the same for all networking
devices on a specific network.
Specifying a smaller dead interval (seconds) will give faster detection of a neighbor being down and
improve convergence, but might cause more routing instability.
Examples
The following example sets the OSPF dead interval to 20 seconds:
interface eth-0-1
ip ospf dead-interval 20

configuration mode. To restore the OSPF functionality, use the no form of this command.
