VLAN 间通讯实验

一、拓扑图

二、需求

1.pc1 pc3属于VLAN 2
2.pc2 pc4属于VLAN 3
3.通过 DHCP使PC获得IP
4.全网可达

三、需求分析

创建VLAN并划分接口

1.LSW1

[LSW1]vlan 2
[LSW1]int GigabitEthernet 0/0/3
[LSW1-GigabitEthernet0/0/3]port link-type access
[LSW1-port-group-default]port default vlan 2

[LSW1]int GigabitEthernet 0/0/4
[LSW1-GigabitEthernet0/0/4]port link-type access
[LSW1-GigabitEthernet0/0/4]port default vlan 3

 
[LSW1]int GigabitEthernet 0/0/2
[LSW1-GigabitEthernet0/0/2]port link-type trunk 
[LSW1-GigabitEthernet0/0/2]port trunk allow-pass vlan 2 3

[LSW1]int GigabitEthernet 0/0/1
[LSW1-GigabitEthernet0/0/1]port link-type trunk 
[LSW1-GigabitEthernet0/0/1]port trunk allow-pass vlan 2 3

2.LSW2

[LSW2]vlan 2
[LSW2]int GigabitEthernet 0/0/2
[LSW2-GigabitEthernet0/0/2]port link-type access
[LSW2-GigabitEthernet0/0/2]port default vlan 2

[LSW2]int GigabitEthernet 0/0/3
[LSW2-GigabitEthernet0/0/3]port link-type access 
[LSW2-GigabitEthernet0/0/3]port default vlan 3

[LSW2]int GigabitEthernet 0/0/1
[LSW2-GigabitEthernet0/0/1]port link-type trunk 
[LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 2 3

3.R1

对路由器划分子接口

[R1]int GigabitEthernet 0/0/0.1
[R1-GigabitEthernet0/0/0.1]ip address 192.168.1.254 24

[R1-GigabitEthernet0/0/0.1]in g 0/0/0.2
[R1-GigabitEthernet0/0/0.2]ip address 192.168.2.254 24

定义子接口的VLAN 信息并开启接口的ARP应答功能

[R1-GigabitEthernet0/0/0.1]ip address 192.168.1.254 24
[R1-GigabitEthernet0/0/0.1]dot1q termination vid 2
[R1-GigabitEthernet0/0/0.1]arp broadcast enable 
[R1-GigabitEthernet0/0/0.1]in g 0/0/0.2	
[R1-GigabitEthernet0/0/0.2]ip address 192.168.2.254 24
[R1-GigabitEthernet0/0/0.2]dot1q termination vid 3
[R1-GigabitEthernet0/0/0.2]arp broadcast enable

通过 DHCP使PC获得IP

[R1]dhcp enable 
Info: The operation may take a few seconds. Please wait for a moment.done.
[R1]ip pool www
Info: It's successful to create an IP address pool.
[R1-ip-pool-www]network 192.168.1.0 mask 24	
[R1-ip-pool-www]gateway-list 192.168.1.254
[R1-ip-pool-www]dns-list 8.8.8.8
[R1]int GigabitEthernet 0/0/0.1
[R1-GigabitEthernet0/0/0.1]dhcp select global


[R1]ip pool mmm
Info: It's successful to create an IP address pool.
[R1-ip-pool-mmm]network 192.168.2.0 mask 24
[R1-ip-pool-mmm]gateway-list 192.168.2.254
[R1-ip-pool-mmm]dns-list 8.8.8.8
[R1]int GigabitEthernet 0/0/0.2
[R1-GigabitEthernet0/0/0.2]dhcp select global
