Default Not configured
Command Mode INTERFACE
Usage
Information
The no version of this command removes an interface from an OSPF area.
Example

ip ospf authentication-key
Configures a text authentication key to enable OSPF traffic on an interface.
Syntax
ip ospf authentication-key key
Parameters key — Enter an eight-character string for the authentication key.
Defaults Not configured
Command Mode INTERFACE
Usage
Information
To exchange OSPF information, all neighboring routers in the same network must use the same
authentication key. The no version of this command deletes the authentication key.
Example
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# ip ospf authentication-key sample
Supported
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, from 1 to 65335.
Default Based on bandwidth reference
Command Mode INTERFACE
Usage
Information
if not configured, interface cost is based on the auto-cost command. 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, from 1 to 65535.
