一、实验拓扑
二、实验要求
1、pc1和pc3所在接口为access;属于vlan2;
pc可以号间pe.ce0不一网段: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获职IP地址，且pc1/pc3可以正常访问pc2/pc4/pc5/pc6;
三、实验思路
1、PC端设置DHCP自动获取IP地址；
2、创建vlan；
3、进入到交换机的接口下加入VLAN；
4、给路由器的子接口（VLAN 2）和物理接口(VLAN 3/4/5/6 )分别配置IP地址;
5、在路由器上创建两个地址池，并开启DHCP服务；
四、实验步骤
1、PC端设置DHCP自动获取IP地址
2、创建vlan
LSW1VLAN batch 2 to 6
LSW2vlan batch 2 to 6
LSW3vlan batch 2 to 6
3、进入到交换机的接口下加入VLAN
LSW1int g0/0/2
LSW1-GigabitEthernet0/0/2port link-type access
LSW1-GigabitEthernet0/0/2port default vlan 2
LSW1-GigabitEthernet0/0/2int g0/0/3
LSW1-GigabitEthernet0/0/3port hybrid pvid vlan 3
LSW1-GigabitEthernet0/0/3port hybrid untagged vlan 3 to 6
LSW1int g0/0/4
LSW1-GigabitEthernet0/0/4port link-type trunk
LSW1-GigabitEthernet0/0/4port trunk allow-pass vlan 2 to 6
LSW1-GigabitEthernet0/0/4int g0/0/1
LSW1-GigabitEthernet0/0/1port hybrid untagged vlan 3 to 6
LSW1-GigabitEthernet0/0/1port hybrid tagged vlan 2
LSW2-GigabitEthernet0/0/2port link-type accessLSW2-GigabitEthernet0/0/2port default vlan 2
LSW2-GigabitEthernet0/0/2int g 0/0/3
LSW2-GigabitEthernet0/0/3port hybrid pvid vlan 4
LSW2-GigabitEthernet0/0/3port hybrid untagged vlan 3 to 6
LSW2-GigabitEthernet0/0/3int g 0/0/1
LSW2-GigabitEthernet0/0/1port link-type trunk
LSW2-GigabitEthernet0/0/1port trunk allow-pass vlan 2 to 6
LSW2-GigabitEthernet0/0/1int g 0/0/4
LSW2-GigabitEthernet0/0/4port link-type trunk
LSW2-GigabitEthernet0/0/4port trunk allow-pass vlan 2 to 6
LSW3int g 0/0/1LSW3-GigabitEthernet0/0/1port link-type trunk
LSW3-GigabitEthernet0/0/1port trunk allow-pass vlan 2 to 6
LSW3-GigabitEthernet0/0/1]int g 0/0/2
LSW3-GigabitEthernet0/0/2port hybrid pvid vlan 5
LSW3-GigabitEthernet0/0/2port hybrid untagged vlan 3 4 5
LSW3-GigabitEthernet0/0/2int g 0/0/3
LSW3-GigabitEthernet0/0/3port hybrid pvid vlan 6
LSW3-GigabitEthernet0/0/3port hybrid untagged vlan 3 4 6
查看接口下vlan的状态：
4、给路由器的子接口（VLAN 2）和物理接口(VLAN 3/4/5/6 )分别配置IP地址
R1int g 0/0/0
R1-GigabitEthernet0/0/0ip add
R1-GigabitEthernet0/0/0ip address 192.168.1.1 24
R1-GigabitEthernet0/0/0int g 0/0/0.1
R1-GigabitEthernet0/0/0.1ip address 192.168.2.1 24
R1-GigabitEthernet0/0/0.1dot1q termination vid 2 //接口开启802.1q帧识别
R1-GigabitEthernet0/0/0.1arp broadcast enable //开启arp广播协议
查看以下接口的IP地址：
5、在路由器上创建两个地址池，并开启DHCP服务
R1dhcp enable
R1ip pool aa
R1-ip-pool-aanetwork 192.168.2.0 mask 24
R1-ip-pool-aagateway-list 192.168.2.1
R1-ip-pool-aadns-list 8.8.8.8
R1int g 0/0/0.1
R1-GigabitEthernet0/0/0.1dhcp select global
R1dhcp enable
R1ip pool bb
R1-ip-pool-bbnetwork 192.168.1.0 mask 24
R1-ip-pool-bbgateway-list 192.168.1.1
R1-ip-pool-bbdns-list 8.8.8.8
R1int g 0/0/0.1
R1-GigabitEthernet0/0/0dhcp select global
pc2访问pc4/pc5/pc6：
pc4访问pc6：
pc5不能访问pc6：
