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.
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
