vlan实验(三种模式)

一、实验拓扑

二、实验要求

1. PC1和PC3所在接口为access;pvlan vlan2
2. PC2/4/5/6处于同一网段，其中PC2可以访问PC4/5/6；但PC4可以访问PC5，不能访问PC6
3. PC5不能访问PC6
4. PC1/3与PC2/4/6不在一个网段
5. 所有PC通过DHCP获取IP地址，且PC1/3可以正常访问PC2/4/5/6

三、实验思路

1. pc1/pc3–>vlan2 给它们划分一个固定网段为192.168.2.0/24 ，路由器R1为vlan2设置子接口专门管理pc1/pc3,并在子接口上设置DHCP池塘获取IP。因为PC1/3可以正常访问PC2/4/5/6，它们又不在同一个网段，需要路由器进行路由，普通二层交换机无法实现。
2. 由要求2，PC2/4/5/6处于同一网段，需要在交换机上把他们隔离开。 pc2–>vlan3,pc4/pc5–>vlan4,pc6–>vlan5 。
   因为PC2可以访问PC4/5/6；但PC4可以访问PC5，不能访问PC6，
   v3 -----> v4/5
   v4 --/–>v5
   所以pc2与sw1的接口允许vlan3上去，允许vlan3/4 /5下来，且剥离标签
   pc4与sw2的接口和pc5与sw3的接口 允许vlan4上去，允许vlan 3/4下来 pc6与sw3的接口允许vlan5
   上，允许vlan3/5下来。
3. sw1与sw2之间左边配trunk，右边配混杂
4. 由于2456都在一个范围，且都属于混杂模式，允许vlan1进入。在路由器那块，就把2456都看作在vlan1

四、实验配置

1.将接口划入vlan
[sw1]vlan batch 2 to 5
[sw1] int g0/0/1
[sw1-GigabitEthernet0/0/1]port link-type access
[sw1-GigabitEthernet0/0/1]port default vlan 2

[sw1]int g0/0/2
[sw1-GigabitEthernet0/0/2]port hybrid untagged vlan 3 to 5
[sw1-GigabitEthernet0/0/2]port hybrid pvid vlan 3

[sw1]int g0/0/23
[sw1-GigabitEthernet0/0/23]port link-type trunk
[sw1-GigabitEthernet0/0/23]port trunk allow-pass vlan 2 to 5

[sw2] vlan batch 2 to 5
[sw2]int g0/0/23
[sw2-GigabitEthernet0/0/23]port hybrid tagged vlan 2 to 5
[sw2]int g0/0/1
[sw2-GigabitEthernet0/0/1]port link-type access
[sw2-GigabitEthernet0/0/1]port default vlan 2
[sw2]int g0/0/2
[sw2-GigabitEthernet0/0/2]port hybrid untagged vlan 3 to 4
[sw2-GigabitEthernet0/0/2]port hybrid pvid vlan 4
[sw2]int g0/0/24
[sw2-GigabitEthernet0/0/24]port hybrid tagged vlan 2 to 5

[sw3]int g0/0/24
[sw3-GigabitEthernet0/0/24]port hybrid tagged vlan 2 to 5

[sw3]vlan batch 2 to 5
[sw3]int g0/0/1
[sw3-GigabitEthernet0/0/1]port hybrid pvid vlan 4
[sw3-GigabitEthernet0/0/1]port hybrid untagged vlan 3 to 4

[sw3]int g0/0/2
[sw3-GigabitEthernet0/0/2]port hybrid pvid vlan 5
[sw3-GigabitEthernet0/0/2]port hybrid untagged vlan 3 5

2.配置路由器，通过池塘下发地址
[sw1]int g0/0/24
[sw1-GigabitEthernet0/0/24]port hybrid tagged vlan 2
[sw1-GigabitEthernet0/0/24]port hybrid untagged vlan 3 to 5

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip add
[r1-GigabitEthernet0/0/0]ip address 192.168.1.1 24
[r1-GigabitEthernet0/0/0]int g0/0/0.1
[r1-GigabitEthernet0/0/0.1]dot1q termination vid 2
[r1-GigabitEthernet0/0/0.1]ip address 192.168.2.1 24
[r1-GigabitEthernet0/0/0.1]arp broadcast enable

[r1]dhcp enable

3.PC端获取地址

4. 测试
