1. Configure IP interfaces on each network that will be attached to OSPF areas.
2. Enable OSPF.
3. Define the backbone.
4. Define the stub area.
5. Attach the network interface to the backbone.
6. Attach the network interface to the stub area.

NE2552E Application Guide for ENOS 8.4
Follow this procedure to configure OSPF support as shown in Figure
In this example, two IP interfaces are needed:
 Interface 1 for the backbone network on 10.10.7.0/24
 Interface 2 for the stub area network on 10.10.12.0/24
NE2552E(config)# interface ip 1
NE2552E(config-ip-if)# ip address 10.10.7.1 255.255.255.0 enable
NE2552E(config-ip-if)# exit
NE2552E(config)# interface ip 2
NE2552E(config-ip-if)# ip address 10.10.12.1 255.255.255.0 enable
NE2552E(config-ip-if)# exit
Note:
OSPFv2 supports IPv4 only. IPv6 is supported in OSPFv3 (see "OSPFv3
Implementation in Lenovo ENOS" on page
NE2552E(config)# router ospf
NE2552E(config-router-ospf)# enable
The backbone is always configured as a transit area using areaid 0.0.0.0.
NE2552E(config-router-ospf)# area 0 area-id 0.0.0.0
NE2552E(config-router-ospf)# area 0 type transit
NE2552E(config-router-ospf)# area 0 enable
NE2552E(config-router-ospf)# area 1 area-id 0.0.0.1
NE2552E(config-router-ospf)# area 1 type stub
NE2552E(config-router-ospf)# area 1 enable
NE2552E(config-router-ospf)# exit
NE2552E(config)# interface ip 1
NE2552E(config-ip-if)# ip ospf area 0
NE2552E(config-ip-if)# ip ospf enable
NE2552E(config-ip-if)# exit
NE2552E(config)# interface ip 2
NE2552E(config-ip-if)# ip ospf area 1
NE2552E(config-ip-if)# ip ospf enable
NE2552E(config-ip-if)# exit
