题干要求和实验拓扑图：

实验步骤：

1.根据拓扑图配置vlan

由于配置繁琐，我们就对sw1与sw2的配置进行展示：

sw1:

[sw1]vlan batch 2 to 5
[sw1]vlan 2
[sw1]int vlan 2
[sw1-Vlanif2]ip add 10.1.2.254 24
[sw1]vlan 3
[sw1]int vlan 3
[sw1-Vlanif3]ip add 10.1.3.254 24
[sw1]vlan 114
[sw1]int vlan 114
[sw1-Vlanif114]ip add 10.1.114.1 24
[sw1]vlan 100
[sw1]int vlan 100
[sw1-Vlanif100]ip add 10.1.100.254 24
[sw1-Vlanif11]ip add 10.1.11.2 24
g0/0/2接口：
[sw1-GigabitEthernet0/0/2]port link-type trunk
[sw1-GigabitEthernet0/0/2]port trunk allow-pass vlan 2 3
g0/0/3接口：
[sw1-GigabitEthernet0/0/3]port link-type trunk
[sw1-GigabitEthernet0/0/3]port trunk allow-pass vlan 2
g0/0/1接口：
[sw1]int g0/0/1
[sw1-GigabitEthernet0/0/1]port link-type trunk
[sw1-GigabitEthernet0/0/1]port trunk allow-pass vlan 114
g0/0/4接口：
[sw1]int g0/0/4
[sw1-GigabitEthernet0/0/4]port link-type trunk
[sw1-GigabitEthernet0/0/4]port trunk allow-pass vlan 100
g0/0/5接口：
[sw1]int g0/0/5
[sw1-GigabitEthernet0/0/5]port link-type access
[sw1-GigabitEthernet0/0/5]port default vlan 11
创建池子，建立dhcp：
[sw1]ip pool vlan2
[sw1-ip-pool-vlan2]network 10.1.2.0 mask 24
[sw1-ip-pool-vlan2]gateway-list 10.1.2.254
[sw1-Vlanif2]dhcp select global

sw2:

g0/0/1:
[sw2-GigabitEthernet0/0/3]int g0/0/1
[sw2-GigabitEthernet0/0/1]port link-type trunk
[sw2-GigabitEthernet0/0/1]port trunk allow-pass vlan 2 3
g0/0/2：
[sw2]int g0/0/2
[sw2-GigabitEthernet0/0/2]port link-type access
[sw2-GigabitEthernet0/0/2]port default vlan 2
g0/0/3:
[sw2-GigabitEthernet0/0/2]int g0/0/3
[sw2-GigabitEthernet0/0/3]port link-type access
[sw2-GigabitEthernet0/0/3]port default vlan 3
其余同理即可

r1配置：

[r1]ip route-static 0.0.0.0 0 100.1.1.2
[r1]acl 2000
[r1-acl-basic-2000]rule permit source 10.1.0.0 0.0.0.255
[r1-acl-basic-2000]int g0/0/2
[r1-GigabitEthernet0/0/2]nat outbound 2000

2.OSPF配置：

r1:

[r1]ospf 1 router-id 1.1.1.1
[r1-ospf-1]area 0
[r1-ospf-1-area-0.0.0.0]net 10.1.11.0 0.0.0.255
[r1-ospf-1-area-0.0.0.0]net 10.1.14.0 0.0.0.255
[r1-ospf-1]default-route-advertise

[sw1-ospf-1-area-0.0.0.0]dis this
area 0.0.0.0
network 10.1.11.0 0.0.0.255
network 10.1.114.0 0.0.0.255
return
[sw4-ospf-1-area-0.0.0.0]dis this
area 0.0.0.0
network 10.1.114.0 0.0.0.255
network 10.1.14.0 0.0.0.255

sw1:

[sw1]ospf 1 router-id 11.11.11.11
[sw1-ospf-1]area 1
[sw1-ospf-1-area-0.0.0.1]network 10.1.2.0 0.0.0.255
[sw1-ospf-1-area-0.0.0.1]network 10.1.3.0 0.0.0.255
[sw1-ospf-1-area-0.0.0.1]stub no-summary

[sw1-ospf-1]area 3
[sw1-ospf-1-area-0.0.0.3]net 10.1.100.0 0.0.0.255
[sw1-ospf-1-area-0.0.0.3]stub no-summary

[sw1]ospf 1 router-id 11.11.11.11
[sw1-ospf-1]area 1
[sw1-ospf-1-area-0.0.0.1]network 10.1.2.0 0.0.0.255
[sw1-ospf-1-area-0.0.0.1]network 10.1.3.0 0.0.0.255
[sw1-ospf-1-area-0.0.0.1]stub no
[sw1-ospf-1-area-0.0.0.1]stub no-summary

[sw1-ospf-1]area 3
[sw1-ospf-1-area-0.0.0.3]net 10.1.100.0 0.0.0.255
[sw1-ospf-1-area-0.0.0.3]stub no-summary

3.在PC1上对8.8.8.8即公网进行连通性测试：

对sever1进行连通性测试，发现无法连通，经检验为Bug,需删除vlan100线路。
实验完成
