VLAN实验

一、实验拓扑图：

二、实验要求：

1.PC1和PC3所在接口为access；属于vlan2；

pc2/pc4/pc5/pc6处于同一网段；其中pc2可以访问pc4/pc5/pc6；pc4可以访问pc6；pc5不能访问pc6；

2、pc1/pc3与pc2/pc4/pc5/pc6不在同一网段；

3、所有pc通过DHCP获取IP地址，且pc1/pc3可以正常访问pc2/pc4/pc5/pc6；

三、实验步骤

1.创建VLAN：

[SW1]vlan batch 2 to 6

[SW2]vlan batch 2 to 6

[SW3]vlan batch 2 to 6

查看vlan是否创建成功

[SW2]dis vlan

2.把接口划分到对应的vlan里面：

[SW1]int g 0/0/1

[SW1-GigabitEthernet0/0/1]port link-type access

[SW1-GigabitEthernet0/0/1]port default vlan 2

[SW1-GigabitEthernet0/0/1]int g 0/0/2

[SW1-GigabitEthernet0/0/2]port hybrid pvid vlan 3

[SW1-GigabitEthernet0/0/2]port hybrid untagged vlan 3 to 6

[SW1]int g 0/0/3

[SW1-GigabitEthernet0/0/3]port link-type trunk

[SW1-GigabitEthernet0/0/3]port trunk allow-pass vlan 2 to 6

[SW1]dis port vlan active

[SW2-GigabitEthernet0/0/1]port link-type access

[SW2-GigabitEthernet0/0/1]port default vlan 2

[SW2-GigabitEthernet0/0/2]port hybrid pvid vlan 4

[SW2-GigabitEthernet0/0/2]port hybrid untagged vlan 3 to 6

[SW2-GigabitEthernet0/0/3]port link-type trunk

[SW2-GigabitEthernet0/0/3]port trunk allow-pass vlan 2 to 6

[SW2-GigabitEthernet0/0/4]port link-type trunk

[SW2-GigabitEthernet0/0/4]port trunk allow-pass vlan 2 to 6

[SW3-GigabitEthernet0/0/1]port hybrid untagged vlan 3 4 5

[SW3-GigabitEthernet0/0/2]port hybrid pvid vlan 6

[SW3-GigabitEthernet0/0/2]port hybrid untagged vlan 3 4 6

[SW3-GigabitEthernet0/0/3]port link-type trunk

[SW3-GigabitEthernet0/0/3]port trunk allow-pass vlan 2 to 6

[SW1]int g 0/0/4

[SW1-GigabitEthernet0/0/4]port hybrid untagged vlan 3 4 5 6

[SW1-GigabitEthernet0/0/4]port hybrid vlan 2

在R1上创建地址池，下发dhcp服务

[R1-GigabitEthernet0/0/0]ip add 192.168.1.1 24

[R1-GigabitEthernet0/0/0]int g 0/0/0.1

[R1-GigabitEthernet0/0/0.1]ip add 192.168.2.1 24

[R1-GigabitEthernet0/0/0.1]dot1q termination vid 2

[R1-GigabitEthernet0/0/0.1]arp broadcast enable

[R1]dhcp enable

[R1]ip policy-based-route

[R1]ip pool aa

[R1-ip-pool-aa]network 192.168.1.0 mask 24

[R1-ip-pool-aa]gateway-list 192.168.1.1

[R1-ip-pool-aa]dns-list 8.8.8.8

[R1-GigabitEthernet0/0/0]dhcp select global

[R1]ip pool bb

[R1-ip-pool-bb]network 192.168.2.0 mask 24

[R1-ip-pool-bb]gateway-list 192.168.2.1        

[R1-ip-pool-bb]dns-list 8.8.8.8

[R1]int g 0/0/0.1

[R1-GigabitEthernet0/0/0.1]dhcp select global
