no ip ospf (A.B.C.D) dead-interval

Parameters

A.B.C.D

optional parameter.

between 1 and 65,535. The default interval is 40
seconds.

Description

Use the IP OSPF DEAD-INTERVAL command to set the interval during
which no hello packets are received and after which a neighbor is declared
dead.

The dead-interval is the amount of time that the router waits to receive an
OSPF hello packet from the neighbor before declaring the neighbor down.
This value is advertised in the router’s hello packets. It must be a multiple
of the hello-interval and be the same for all routers on a specific network.

Use the no form of this command to return to the default time. If you have
configured this command specifying the IP address of the interface and
want to remove the configuration, use the no form of this command with
the specified IP address.

Command Mode

Interface mode

Example

The following example shows configuring dead-interval for 10 seconds on
interface 2:

switch# configure terminal

switch(config)# interface xe2

switch(config-if)# ip ospf dead-interval 10
