Chapter 38 Configuring IP Unicast Routing
Configuring OSPF
To end an OSPF routing process, use the
no router ospf
process-id
global configuration command.
This example shows how to configure an OSPF routing process and assign it a process ID of 109:
Switch(config)#
router ospf 109
Switch(config-router)#
network 131.108.0.0 255.255.255.0 area 24
Configuring OSPF Interfaces
You can use the
ip ospf
interface configuration commands to modify interface-specific OSPF
parameters. You are not required to modify any of these parameters, but some interface parameters (hello
interval, dead interval, and authentication key) must be consistent across all routers in an attached
network. If you modify these parameters, be sure all routers in the network have compatible values.
Beginning in privileged EXEC mode, follow these steps to modify OSPF interface parameters:
Step 6
show ip protocols
Verify your entries.
Step 7
copy running-config startup-config
(Optional) Save your entries in the configuration file.

Step 1

Enter global configuration mode.
Step 2
interface
interface-id
Enter interface configuration mode, and specify the Layer 3 interface
to configure.
Step 3
ip ospf
cost
(Optional) Specify the cost of sending a packet on the interface.
Step 4
ip ospf retransmit-interval
seconds
(Optional) Specify the number of seconds between link-state
advertisement transmissions. The range is 1 to 65535 seconds. The
default is 5 seconds.
Step 5
ip ospf transmit-delay
seconds
(Optional) Set the estimated number of seconds to wait before
sending a link state update packet. The range is 1 to 65535 seconds.
The default is 1 second.
Step 6
ip ospf priority
number
(Optional) Set priority to help find the OSPF designated router for a
network. The range is from 0 to 255. The default is 1.
Step 7
ip ospf hello-interval
seconds
(Optional) Set the number of seconds between hello packets sent on
an OSPF interface. The value must be the same for all nodes on a
network. The range is 1 to 65535 seconds. The default is 10 seconds.
Step 8
ip ospf dead-interval
seconds
(Optional) Set the number of seconds after the last device hello
packet was seen before its neighbors declare the OSPF router to be
down. The value must be the same for all nodes on a network. The
range is 1 to 65535 seconds. The default is 4 times the hello interval.
Step 9
ip ospf authentication-key
key
(Optional) Assign a password to be used by neighboring OSPF
routers. The password can be any string of keyboard-entered
characters up to 8 bytes in length. All neighboring routers on the
same network must have the same password to exchange OSPF
information.
