Configuring IP Routing
This example shows how to configure an OSPF routing process and assign it a process number of 1:
Router(config)# router ospf 1
Router(config-router)# network 192.168.1.0 0.0.0.255 area 0
This is an example of output from the show ip protocols privileged EXEC command that verifies the
OSPF process ID.
Router# show ip protocols
Routing Protocol is "ospf 1"
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Router ID 192.168.3.1
Number of areas in this router is 1. 1 normal 0 stub 0 nssa
Maximum path: 4
Routing for Networks:
192.168.2.0 0.0.0.255 area 0
192.168.3.0 0.0.0.255 area 0
Routing Information Sources:
Gateway Distance Last Update
192.168.3.1 110 00:03:34
192.168.2.1 110 00:03:34
Distance: (default is 110)
OSPF Interface Parameters
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.
Note The ip ospf interface configuration commands are all optional.
Beginning in privileged EXEC mode, follow these steps to modify OSPF interface parameters:
Command Purpose
Step 1
Router# configure terminal
Enters global configuration mode.
Step 2
Router(config)# interface
interface-id
Enters interface configuration mode, and specifies the
Layer 3 interface to configure.
Step 3
Router(config-if)# ip ospf
cost
(Optional) Explicitly specifies the cost of sending a packet
on the interface.
Step 4
Router(config-if)# ip ospf
retransmit-interval
seconds
(Optional) Specifies the number of seconds between link
state advertisement transmissions. The range is 1 to 65535
seconds. The default is 5 seconds.
Step 5
Router(config-if)# ip ospf
transmit-delay
seconds
(Optional) Sets 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
Router(config-if)# ip ospf priority
number
(Optional) Sets priority to help determine the OSPF
designated router for a network. The range is from 0 to 255.
The default is 1.
