Example
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# ip ospf authentication-key sample

Releases
10.3.0E or later
ip ospf cost
Changes the cost associated with the OSPF traffic on an interface.
Syntax
ip ospf cost cost
Parameters cost — Enter a value as the OSPF cost for the interface (1 to 65335).
Default Based on bandwidth reference
Command Mode INTERFACE
Usage
Information
Interface cost is based on the auto-cost command if not configured. This command configures OSPF
over multiple vendors to ensure that all routers use the same cost. If you manually configure the cost, the
calculated cost based on the reference bandwidth does not apply to the interface. The no version of this
command removes the IP OSPF cost configuration.
Example
OS10(config)# interface vlan 10
OS10(conf-if-vl-1)# ip ospf cost 10
Supported
Releases
10.2.0E or later
ip ospf dead-interval
Sets the time interval since the last hello-packet was received from a router. After the interval elapses, the neighboring routers
declare the router dead.
Syntax
ip ospf dead-interval seconds
Parameters seconds — Enter the dead interval value in seconds (1 to 65535).
Default 40 seconds
Command Mode INTERFACE
Usage
Information
The dead interval is four times the default hello-interval by default. The no version of this command
resets the value to the default.
Example
OS10(conf-if-vl-10)# ip ospf dead-interval 10
Supported
Releases
10.2.0E or later
ip ospf hello-interval
Sets the time interval between the hello packets sent on the interface.
Syntax
ip ospf hello-interval seconds
Parameters seconds — Enter the hello-interval value in seconds (1 to 65535).
Default 10 seconds
Command Mode INTERFACE
Usage
Information
All routers in a network must have the same hello time interval between the hello packets. The no version
of the this command resets the value to the default.
