Reference Guide
Parameters cost — Enter a value as the OSPF cost for the interface (1 to 65335).
Default 1
Command Mode INTERFACE
Usage Information Interface cost is based on the auto-cost command if not congured. This command congures OSPF over
multiple vendors to ensure that all routers use the same cost. If you manually congure 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 conguration.
Example
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 removes the
IP OSPF cost conguration.
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.
Example
OS10(conf-if-vl-10)# ip ospf hello-interval 30
Supported Releases 10.2.0E or later
