VLAN实验
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
