Follow this procedure to configure OSPF support as shown in Figure 12-7:

1.Configure IP interfaces for each network which will be attached to OSPF areas.

>> # /cfg/l3/if	1	# addr 10.10.7.1	(Select menu for IP interface 1)
>> IP Interface	1	# addr 10.10.7.1	(Set IP address on backbone network)
>> IP Interface 1 # mask 255.255.255.0			(Set IP mask on backbone network)
>> IP Interface	1	# ena	(Enable IP interface 1)
>> IP Interface 1 # ../if 2			(Select menu for IP interface 2)
>> IP Interface	2	# addr 36.128.192.1	(Set IP address on stub area network)
>> IP Interface 2 # mask 255.255.192.0			(Set IP mask on stub area network)
>> IP Interface	2	# ena	(Enable IP interface 2)

2.Enable OSPF.

>> IP Interface 2 # /cfg/l3/ospf/on (Enable OSPF on the switch)

3. Define the backbone.

	>> Open Shortest Path First #					aindex 0	(Select menu for area index 0)
	>> OSPF Area (index) 0			# areaid 0.0.0.0			(Set the ID for backbone area 0)
	>> OSPF	Area	(index) 0	#	type	transit	(Define backbone as transit type)
	>> OSPF	Area	(index) 0	#	enable		(Enable the area)

4. Define the stub area.

	>> OSPF Area	(index) 0 #		../aindex 1	(Select menu for area index 1)
	>> OSPF Area	(index) 1	#	areaid 0.0.0.1	(Set the area ID for OSPF area 1)
	>> OSPF Area	(index) 1	#	type stub	(Define area as stub type)
	>> OSPF Area	(index) 1	#	enable	(Enable the area)

5. Attach the network interface to the backbone.

	>> OSPF Area (index) 1 # ../if 1				(Select OSPF menu for IP interface 1)
	>> OSPF Interface	1	#	aindex 0	(Attach network to backbone index)
	>> OSPF Interface	1	#	enable	(Enable the backbone interface)

6. Attach the network interface to the stub area.

>> OSPF Interface 1		# ../if 2			(Select OSPF menu for IP interface 2)
>> OSPF Interface	2	#	aindex	1	(Attach network to stub area index)
>> OSPF Interface	2	#	enable		(Enable the stub area interface)
