1. 配置各接口所属的VLAN
[LSW1]vlan batch 13 14
[LSW1-GigabitEthernet0/0/3]port link-type trunk
[LSW1-GigabitEthernet0/0/3]port trunk allow-pass vlan 13
[LSW1-GigabitEthernet0/0/4]port link-type trunk
[LSW1-GigabitEthernet0/0/4]port trunk allow-pass vlan 14
[LSW2]vlan batch 23 24
[LSW2-GigabitEthernet0/0/3]port link-type trunk
[LSW2-GigabitEthernet0/0/3]port trunk allow-pass vlan 23
[LSW2-GigabitEthernet0/0/4]port link-type trunk
[LSW2-GigabitEthernet0/0/4]port trunk allow-pass vlan 24
[LSW3]vlan batch 13 23
[LSW3-GigabitEthernet0/0/1]port link-type trunk
[LSW3-GigabitEthernet0/0/1]port trunk allow-pass vlan 13
[LSW3-GigabitEthernet0/0/2]port link-type trunk
[LSW3-GigabitEthernet0/0/2]port trunk allow-pass vlan 23
[LSW4]vlan batch 14 24
[LSW4-GigabitEthernet0/0/1]port link-type trunk
[LSW4-GigabitEthernet0/0/1]port trunk allow-pass vlan 14
[LSW4-GigabitEthernet0/0/2]port link-type trunk
[LSW4-GigabitEthernet0/0/2]port trunk allow-pass vlan 24
2. 配置各接口的IP地址
[LSW1-Vlanif13]ip add 10.1.13.1 24
[LSW1-Vlanif14]ip add 10.1.14.1 24
[LSW2-Vlanif23]ip add 10.1.23.2 24
[LSW2-Vlanif24]ip add 10.1.24.2 24
[LSW3-Vlanif13]ip add 10.1.13.3 24
[LSW3-Vlanif23]ip add 10.1.23.3 24
[LSW4-Vlanif14]ip add 10.1.14.4 24
[LSW4-Vlanif24]ip add 10.1.24.4 24
[LSW1]int LoopBack 0
[LSW1-LoopBack0]ip add 10.1.1.1 32
[LSW2]int LoopBack 0
[LSW2-LoopBack0]ip add 10.2.2.2 32
[LSW3]int LoopBack 0
[LSW3-LoopBack0]ip add 10.3.3.3 32
[LSW4]int LoopBack 0
[LSW4-LoopBack0]ip add 10.4.4.4 32
3. 配置OSPF基本功能
[LSW1]ospf 1 router-id 10.1.1.1
[LSW1-ospf-1]area 0
[LSW1-ospf-1-area-0.0.0.0]network 10.1.13.0 0.0.0.255
[LSW1-ospf-1]area 10
[LSW1-ospf-1-area-0.0.0.10]network 10.1.14.0 0.0.0.255
[LSW2]ospf 1 router-id 10.2.2.2
[LSW2-ospf-1]area 0
[LSW2-ospf-1-area-0.0.0.0]network 10.1.23.0 0.0.0.255
[LSW2-ospf-1]area 10
[LSW2-ospf-1-area-0.0.0.10]network 10.1.24.0 0.0.0.255
[LSW3]ospf 1 router-id 10.3.3.3
[LSW3-ospf-1]area 0
[LSW3-ospf-1-area-0.0.0.0]network 10.1.13.0 0.0.0.255
[LSW3-ospf-1-area-0.0.0.0]network 10.1.23.0 0.0.0.255
[LSW4]ospf 1 router-id 10.4.4.4
[LSW4-ospf-1]area 10
[LSW4-ospf-1-area-0.0.0.10]network 10.1.14.0 0.0.0.255
[LSW4-ospf-1-area-0.0.0.10]network 10.1.24.0 0.0.0.255
4. 配置Area10区域为NSSA区域
[LSW1]ospf 1
[LSW1-ospf-1]area 10
[LSW2]ospf 1
[LSW2-ospf-1]area 10
[LSW2-ospf-1-area-0.0.0.10]nssa
[LSW4]ospf 1
[LSW4-ospf-1]area 10
[LSW4-ospf-1-area-0.0.0.10]nssa
5. 配置LSW4引入静态路由
[LSW4]ip route-static 10.1.0.0 16 NULL 0
[LSW4]ospf 1
[LSW4-ospf-1]import-route static
可以看出NSSA区域引入的AS外部路由是通过LSW1向其他区域发布的，即LSW1将Type7 LSA转换成了Type5 LSA
6. 配置LSW2为转换路由器
[LSW2]ospf 1
[LSW2-ospf-1]area 10
[LSW2-ospf-1-area-0.0.0.10]nssa translator-always
7. 验证配置
可以看出NSSA区域引入的AS外部路由是通过LSW2向其他区域发布的，即LSW2成了转换路由器
