VLAN 实验

实验要求及拓扑

实验内容及步骤

1、合理划分网段
将PC1、PC3划分在192.168.1.0 / 24中，PC2、PC4、PC5、PC6划分在192.168.2.0 / 24中

2、 SW1、SW2、SW3上配置VLAN及各个接口类型的配置
SW1

[sw1]vlan batch 2 to 6
[sw1]int g0/0/1
[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 4 5 6
[sw1-GigabitEthernet0/0/2]int g0/0/3
[sw1-GigabitEthernet0/0/3]port link-type trunk
[sw1-GigabitEthernet0/0/3]port trunk allow-pass vlan all
[sw1]int g 0/0/4
[sw1-GigabitEthernet0/0/4]port hybrid untagged vlan 3 4 5 6
[sw1-GigabitEthernet0/0/4]port hybrid tagged vlan 2

SW2

[sw2]vlan batch 2 to 6
[sw2]int g 0/0/3
[sw2-GigabitEthernet0/0/3]port link-type trunk
[sw2-GigabitEthernet0/0/3]port trunk allow-pass vlan all
[sw2-GigabitEthernet0/0/3]int g0/0/1
[sw2-GigabitEthernet0/0/1]port link-type access
[sw2-GigabitEthernet0/0/1]port default vlan 2
[sw2-GigabitEthernet0/0/1]int g0/0/2
[sw2-GigabitEthernet0/0/2]port hybrid pvid vlan 4
[sw2-GigabitEthernet0/0/2]port hybrid untagged vlan 3 4 5
[sw2-GigabitEthernet0/0/2]int g0/0/4
[sw2-GigabitEthernet0/0/4]port link-type trunk
[sw2-GigabitEthernet0/0/4]port trunk allow-pass vlan all

SW3

[sw3]vlan batch 2 to 6
[sw3]int g0/0/3
[sw3-GigabitEthernet0/0/3]port link-type trunk
[sw3-GigabitEthernet0/0/3]port trunk allow-pass vlan all
[sw3-GigabitEthernet0/0/3]int g 0/0/1
[sw3-GigabitEthernet0/0/1]port hybrid pvid vlan 5
[sw3-GigabitEthernet0/0/1]port hybrid untagged vlan 3 4 5
[sw3-GigabitEthernet0/0/1]int g 0/0/2
[sw3-GigabitEthernet0/0/2]port hybrid pvid vlan 6
[sw3-GigabitEthernet0/0/2]port hybrid untagged vlan 3 6

3、在R1上配置DHCP及子接口

R1

[r1]int g0/0/0.1
[r1-GigabitEthernet0/0/0.1]ip a 192.168.1.1 24
[r1-GigabitEthernet0/0/0.1]dot1q termination vid 2
[r1-GigabitEthernet0/0/0.1]arp broadcast enable
[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip a 192.168.2.1 24
[r1]dhcp enable
[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 114.114.114.114
[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 114.114.114.114
[r1]int g 0/0/0.1
[r1-GigabitEthernet0/0/0.1]dhcp select global
[r1]int g 0/0/0
[r1-GigabitEthernet0/0/0]dhcp select global

实验验证及结果
