142IP Routing Configuration and Management

Configure R1 in stub area 2 with the Router-ID 1.1.1.5. Add the

OSPF interfaces to area 2 and enable OSPF on these interfaces.

5530-24TFD(config-router)# router-id 1.1.1.5

5530-24TFD(config-router)# area 0.0.0.2 import noexternal

5530-24TFD(config-router)# network 10.1.1.18 area 0.0.0.2

5530-24TFD(config-router)# network 172.3.3.1 area 0.0.0.2

5530-24TFD(config)# router ospf enable

2Configure router R2.

a.Configure the OSPF interface on R2.

Configure port 2/6 as a brouter port in VLAN 100.

5530-24TFD(config)# interface fast 2/6

5530-24TFD(config-if)# brouter port 2/6 vlan 100 subnet 10.1.1.17/30

b.Configure the second OSPF interface on R2.

Configure port 2/1 as a brouter port in VLAN 300. Enable OSPF on this interface.

5530-24TFD(config)# interface fast 2/1

5530-24TFD(config-if)# brouter port 2/1 vlan 300 subnet 10.1.1.22/30

5530-24TFD(config-if)# ip ospf enable

c.Enable OSPF on R2.

Configure R2 in stub area 2 with an area default cost of 10. Disable import summary to prevent R2 from sending summary LSAs of area 0 into area 2. R2 will originate only summary LSA for default route into area 2. Note that, by default, OSPF interface 10.1.1.22 is placed into OSPF area 0.0.0.0. Because one additional area of 0.0.0.2 is added and OSPF interface 10.1.1.17 is added to area 0.0.0.2, R2 automatically becomes a stub ABR.

5530-24TFD(config-router)# router-id 1.1.1.2

5530-24TFD(config-router)# area 0.0.0.2 import noexternal

5530-24TFD(config-router)# no area 0.0.0.2 import-summary enable

5530-24TFD(config-router)# area 0.0.0.2 default-cost 10

5530-24TFD(config-router)# network 10.1.1.17 area 0.0.0.2

5530-24TFD(config)# router ospf enable
