VLAN实验 - 技术栈

一、实验拓扑

二、实验需求

1、全网可达

2、使用DHCP获取IP地址

三、实验思路

1、划分地址、进行地址配置

2、vlan配置：

划分vlan；

更改接口的链路类型，将相应的接口加入vlan；

在trunk链路上放行网络中的vlan

3、配置子接口

4、DHCP配置

四、实验步骤

1、创建vlan

$SW1$ vlan 2

$SW1-vlan2$ vlan 3

$SW2$ vlan 2

$SW2-vlan2$ vlan 3

$SW3$ vlan 2

$SW3-vlan2$ vlan 3

2、接口加入相应vlan，配置trunk链路，精确放行相应VLAN

$SW1$ int e0/0/2

$SW1-Ethernet0/0/2$ port link-type access

$SW1-Ethernet0/0/2$ port default vlan 2

$SW1-Ethernet0/0/2$ int e0/0/3

$SW1-Ethernet0/0/3$ port link-type access

$SW1-Ethernet0/0/3$ port default vlan 3

$SW1-Ethernet0/0/3$ int e0/0/1

$SW1-Ethernet0/0/1$ port link-type trunk

$SW1-Ethernet0/0/1$ port trunk allow-pass vlan 2 3

$SW2$ int e0/0/3

$SW2-Ethernet0/0/3$ port link-type access

$SW2-Ethernet0/0/3$ port default vlan 2

$SW2-Ethernet0/0/3$ int e0/0/4

$SW2-Ethernet0/0/4$ port link-type access

$SW2-Ethernet0/0/4$ port default vlan 3

$SW2-Ethernet0/0/4$ int e0/0/2

$SW2-Ethernet0/0/2$ port link-type trunk

$SW2-Ethernet0/0/2$ port trunk allow-pass vlan 2 3

$SW2$ int e0/0/1

$SW2-Ethernet0/0/1$ port link-type trunk

$SW2-Ethernet0/0/1$ port trunk allow-pass vlan 2 3

$SW3$ int e0/0/2

$SW3-Ethernet0/0/2$ port link-type access

$SW3-Ethernet0/0/2$ port default vlan 2

$SW3-Ethernet0/0/2$ int e0/0/3

$SW3-Ethernet0/0/3$ port link-type access

$SW3-Ethernet0/0/3$ port default vlan 3

$SW3-Ethernet0/0/3$ int e0/0/1

$SW3-Ethernet0/0/1$ port link-type trunk

$SW3-Ethernet0/0/1$ port trunk allow-pass vlan 2 3

3、在路由器上配置路由信息或者子接口信息，实现全网通

$R1$ int g0/0/0.2

$R1-GigabitEthernet0/0/0.2$ ip a 192.168.1.254 24

$R1-GigabitEthernet0/0/0.2$ dot1q termination vid 2

$R1-GigabitEthernet0/0/0.2$ arp broadcast enable

$R1$ int g0/0/0.3

$R1-GigabitEthernet0/0/0.3$ ip a 192.168.2.254 24

$R1-GigabitEthernet0/0/0.3$ dot1q termination vid 3

$R1-GigabitEthernet0/0/0.3$ arp broadcast enable

$R1$ int g0/0/1.2

$R1-GigabitEthernet0/0/1.2$ ip a 192.168.3.254 24

$R1-GigabitEthernet0/0/1.2$ dot1q termination vid 2

$R1-GigabitEthernet0/0/1.2$ arp broadcast enable

$R1$ int g0/0/1.3

$R1-GigabitEthernet0/0/1.3$ ip a 192.168.4.254 24

$R1-GigabitEthernet0/0/1.3$ dot1q termination vid 3

$R1-GigabitEthernet0/0/1.3$ arp broadcast enable

4、DHCP配置

$R1$ dhcp enable

$R1$ ip pool aa

$R1-ip-pool-aa$ net 192.168.1.0 mask 24

$R1-ip-pool-aa$ gateway-list 192.168.1.254

$R1-ip-pool-aa$ dns-list 114.114.114.114 8.8.8.8

$R1$ int g0/0/0.2

$R1-GigabitEthernet0/0/0.2$ dhcp select global

$R1$ ip pool bb

$R1-ip-pool-bb$ net 192.168.2.0 mask 24

$R1-ip-pool-bb$ gateway-list 192.168.2.254

$R1-ip-pool-bb$ dns-list 114.114.114.114 8.8.8.8

$R1$ int g0/0/0.3

$R1-GigabitEthernet0/0/0.3$ dhcp select global

$R1$ ip pool cc

$R1-ip-pool-cc$ net 192.168.3.0 mask 24

$R1-ip-pool-cc$ gateway-list 192.168.3.254

$R1-ip-pool-cc$ dns-list 114.114.114.114 8.8.8.8

$R1$ int g0/0/1.2

$R1-GigabitEthernet0/0/1.2$ dhcp select global

$R1$ ip pool dd

$R1-ip-pool-dd$ net 192.168.4.0 mask 24

$R1-ip-pool-dd$ gateway-list 192.168.4.254

$R1-ip-pool-dd$ dns-list 114.114.114.114 8.8.8.8

$R1$ int g0/0/1.3

$R1-GigabitEthernet0/0/1.3$ dhcp select global
