题目：

操作：

1.进行VLAN划分以及配置DHCP服务
以R1为例：
[Huawei]interface GigabitEthernet0/0/1.1
[Huawei-GigabitEthernet0/0/1.1]ip address 192.168.1.65 27
[Huawei-GigabitEthernet0/0/1.1]q
[Huawei]interface GigabitEthernet 0/0/1.2
[Huawei-GigabitEthernet0/0/1.2]ip address 192.168.1.97 27
划分VLAN
[Huawei]vlan 2
[Huawei-vlan2]vlan 3
[Huawei-vlan3]q
[Huawei]interface Ethernet 0/0/2
[Huawei-Ethernet0/0/2]port link-type access
[Huawei-Ethernet0/0/2]port default vlan 2
[Huawei]interface Ethernet 0/0/3
[Huawei-Ethernet0/0/3]port link-type access
[Huawei-Ethernet0/0/3]port default vlan 2
[Huawei]interface Ethernet 0/0/4
[Huawei-Ethernet0/0/4]port link-type access
[Huawei-Ethernet0/0/4]port default vlan 3
[Huawei]dhcp enable
[Huawei]ip pool a
[Huawei-ip-pool-a]network 192.168.1.64 mask 27
[Huawei-ip-pool-a]gateway-list 192.168.1.65
[Huawei-ip-pool-a]dns-list 114.114.114.114 8.8.8.8
[Huawei]ip pool b
[Huawei-ip-pool-a]network 192.168.1.96 mask 27
[Huawei-ip-pool-a]gateway-list 192.168.1.97
[Huawei-ip-pool-a]dns-list 114.114.114.114 8.8.8.8
开启服务：
[Huawei]interface GigabitEthernet0/0/1.1
[Huawei-GigabitEthernet0/0/1.1]dhcp select global
[Huawei]interface GigabitEthernet0/0/1.2
[Huawei-GigabitEthernet0/0/1.2]dhcp select global
2.启动ospf协议
R1上配置：
[Huawei]ospf 1 router-id 192.168.1.1
[Huawei-ospf-1]area 0
[Huawei-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255
R2上配置：
[R2]ospf 1 router-id 192.168.1.129
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255
配置trunk干道：
[LSW1]interface Ethernet 0/0/1
[LSW1-Ethernet0/0/1]port link-type trunk
[LSW1-Ethernet0/0/1]port trunk allow-pass vlan all
[LSW2]interface GigabitEthernet 0/0/1
[LSW2-GigabitEthernet0/0/1]port link-type trunk
[LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan all
3.在路由器R1，R2上设置telnet登录；
[r1]aaa
[r1-aaa]local-user abc privilege level 15 password cipher 123456
[r1-aaa]local-user abc service-type telnet
[r1]user-interface vty 0 4
[r1-ui-vty0-4]authentication-mode aaa
[r2]aaa
[r2-aaa]local-user cba privilege level 15 password cipher 123456
[r2-aaa]local-user cba service-type telnet
[r2]user-interface vty 0 4
[r2-ui-vty0-4]authentication-mode aaa
R1上设置策略：
[r1-acl-adv-3001]rule deny tcp source 192.168.1.93 0 destination 192.168.1.1 0 destination-port eq 23
[r1-acl-adv-3001]rule deny tcp source 192.168.1.93 0 destination 192.168.1.65 0 destination-port eq 23
[r1-acl-adv-3001]rule deny tcp source 192.168.1.93 0 destination 192.168.1.97 0 destination-port eq 23
调用该命令
[r1-GigabitEthernet0/0/1]traffic-filter inbound acl 3000
4.通过公有IP12.1.1.1使得PC1-PC4可以访问PC5 ：
[r2-acl-basic-2000]rule permit source 192.168.0.0 0.0.255.255
[r2]interface GigabitEthernet 0/0/2
[r2-GigabitEthernet0/0/2]nat outbound 2000
[r2]ip route-static 0.0.0.0 0.0.0.0 1.1.1.0
即PC1-PC4可以访问PC5

测试成功
