一、规划IP地址
Vlan2：192.168.1.0/24
Vlan3、4、5：192.168.2.0/24
二、创建vlan
SW1:
[SW1]vlan batch 2 to 5
SW2:
[SW2]vlan batch 2 to 5
SW3:
[SW3]vlan batch 2 to 5
三、trunk干道
SW1：
[SW1-GigabitEthernet0/0/1]int g0/0/4
[SW1-GigabitEthernet0/0/4]port link-type trunk
[SW1-GigabitEthernet0/0/4]port trunk allow-pass vlan 2 to 5
通过使用混杂模式来区分vlan2 和其它vlan的标签在到路由器时的撕与不撕
[SW1]int g0/0/1
[SW1-GigabitEthernet0/0/1]port link-type hybrid
[SW1-GigabitEthernet0/0/1]port hybrid untagged vlan 3 to 5
[SW1-GigabitEthernet0/0/1]port hybrid tagged vlan 2
SW2：
[SW2]int g0/0/1
[SW2-GigabitEthernet0/0/1]port link-type trunk
[SW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 2 to 5
[SW2-GigabitEthernet0/0/1]int g0/0/2
[SW2-GigabitEthernet0/0/2]port link-type trunk
[SW2-GigabitEthernet0/0/2]port trunk allow-pass vlan 2 to 5
SW3：
[SW3]int g0/0/1
[SW3-GigabitEthernet0/0/1]port link-type trunk
[SW3-GigabitEthernet0/0/1]port trunk allow-pass vlan 2 to 5
四、接口划分vlan
PC1所在接口：
[SW1]int g0/0/2
[SW1-GigabitEthernet0/0/2]port link-type access
[SW1-GigabitEthernet0/0/2]port default vlan 2
PC3所在接口：
[SW2-GigabitEthernet0/0/2]int g0/0/3
[SW2-GigabitEthernet0/0/3]port link-type access
[SW2-GigabitEthernet0/0/3]port default vlan 2
PC2所在接口：
[SW1]int g0/0/3
[SW1-GigabitEthernet0/0/3]port hybrid pvid vlan 5
[SW1-GigabitEthernet0/0/3]port hybrid untagged vlan 2 to 5
PC4所在接口：
[SW2]int g0/0/4
[SW2-GigabitEthernet0/0/4]port hybrid pvid vlan 3
[SW2-GigabitEthernet0/0/4]port hybrid untagged vlan 2 to 5
PC5所在接口：
[SW3]int g0/0/2
[SW3-GigabitEthernet0/0/2]port hybrid pvid vlan 3
[SW3-GigabitEthernet0/0/2]port hybrid untagged vlan 2 to 5
PC6所在接口：
[SW3-GigabitEthernet0/0/2]int g0/0/03
[SW3-GigabitEthernet0/0/3]port hybrid pvid vlan 4
[SW3-GigabitEthernet0/0/3]port hybrid untagged vlan 2 4 5
SW1：vlan转发规则
SW2：vlan转发规则
SW3：vlan转发规则
五、单臂路由
[R1]int g0/0/0.1
[R1-GigabitEthernet0/0/0.1]ip add 192.168.1.1 24
[R1-GigabitEthernet0/0/0.1]dot1q termination vid 2
[R1-GigabitEthernet0/0/0.1]arp broadcast ena
六、DHCP
[R1]dhcp ena
[R1]ip pool v2
[R1-ip-pool-v2]network 192.168.1.0 mask 255.255.255.0
[R1-ip-pool-v2]gateway-list 192.168.1.1
[R1-ip-pool-v2]dns-list 8.8.8.8
[R1]int g0/0/0.1
[R1-GigabitEthernet0/0/0.1]dhcp select global
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 192.168.2.1 24
[R1]ip pool v345
[R1-ip-pool-v345]gateway-list 192.168.2.1
[R1-ip-pool-v345]network 192.168.2.0 mask 255.255.255.0
[R1-ip-pool-v345]dns-list 8.8.8.8
[R1-GigabitEthernet0/0/0.1]int g0/0/0
[R1-GigabitEthernet0/0/0]dhcp select global
