console(config)#interface vlan 70
console(config-if-vlan70)#ip ospf area 0.0.0.0
console(config-if-vlan70)#ip ospf priority 128
console(config-if-vlan70)#ip ospf cost 32
console(config-if-vlan70)#exit
console(config)#interface vlan 80
console(config-if-vlan80)#ip ospf area 0.0.0.2
console(config-if-vlan80)#ip ospf priority 255
console(config-if-vlan80)#ip ospf cost 64
console(config-if-vlan80)#exit
console(config)#interface vlan 90
console(config-if-vlan90)#ip ospf area 0.0.0.2
console(config-if-vlan90)#ip ospf priority 255
console(config-if-vlan90)#ip ospf cost 64
console(config-if-vlan90)#exit
NOTE: OSPF is globally enabled by default. To make it operational on the
router, you configure OSPF for particular interfaces and identify which area
the interface is associated with.
