Chapter 1 Configuring IP Unicast Routing
Configuring OSPF
Configuring Basic OSPF Parameters
To enable OSPF, create an OSPF routing process, specify the range of IP addresses to associate with the
routing process, and assign area IDs to be associated with that range. Beginning in Cisco IOS
Release 12.2(58)SE, for switches running the IP services image, you can configure either the Cisco
OSPFv2 NSF format or the IETF OSPFv2 NSF format.
Beginning in privileged EXEC mode, follow these steps to enable 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 number of 109:
Switch(config)#
router ospf 109
Switch(config-router)#
network 131.108.0.0 255.255.255.0 area 24
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
router ospf
process-id
Enable OSPF routing, and enter router configuration mode. The
process ID is an internally used identification parameter that is
locally assigned and can be any positive integer. Each OSPF
routing process has a unique value.
Note
OSPF for Routed Access supports only one OSPFv2 and
one OSPFv3 instance with a maximum number of 200
dynamically learned routes.
Step 3
nsf cisco
[
enforce global
]
or
nsf ietf
[
restart-interval
seconds
]
(Optional) Enable Cisco NSF operations for OSPF. The
enforce
global
keyword cancels NSF restart when non-NSF-aware
neighboring networking devices are detected.
(Optional) Enable IETF NSF operations for OSPF. The
restart-interval
keyword specifies the length of the graceful
restart interval, in seconds. The range is from 1 to 1800. The
default is 120.
Step 4
network
address wildcard-mask
area
area-id
Define an interface on which OSPF runs and the area ID for that
interface. You can use the wildcard-mask to use a single
command to define one or more multiple interfaces to be
associated with a specific OSPF area. The area ID can be a
decimal value or an IP address.
Step 5
end
Return to privileged EXEC mode.
Step 6
show ip protocols
Verify your entries.
Step 7
copy running-config startup-config
(Optional) Save your entries in the configuration file.
