目的:

1.实现多交换机不同Vlan间通信.

2.基于三层交换机配置路由,实现全网互通.

拓扑图:

步骤:

1. 配置PC主机的IP,掩码,网关.

2. 在二层交换机LSW1和LSW2上配置VLAN

[Huawei]sysname sw1      //配置LSW1
[sw1]vlan 2
[sw1-vlan2]quit
[sw1]vlan 3
[sw1-vlan3]quit
[sw1]interface e0/0/1
[sw1-Ethernet0/0/1]port link-type access
[sw1-Ethernet0/0/1]port default vlan 1
[sw1-Ethernet0/0/1]quit
[sw1]interface e0/0/2
[sw1-Ethernet0/0/2]port link-type access
[sw1-Ethernet0/0/2]port default vlan 2
[sw1-Ethernet0/0/2]quit
[sw1]interface e0/0/3
[sw1-Ethernet0/0/3]port link-type access
[sw1-Ethernet0/0/3]port default vlan 3
[sw1-Ethernet0/0/3]quit
[sw1]interface g0/0/1
[sw1-GigabitEthernet0/0/1]port link-type trunk
[sw1-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[sw1-GigabitEthernet0/0/1]quit

[Huawei]sysname sw2   //配置LSW2
[sw2]vlan 4
[sw2-vlan4]quit
[sw2]vlan 5
[sw2-vlan5]quit
[sw2]interface e0/0/1
[sw2-Ethernet0/0/1]port link-type access
[sw2-Ethernet0/0/1]port default vlan 4
[sw2-Ethernet0/0/1]quit
[sw2]interface e0/0/2
[sw2-Ethernet0/0/2]port link-type access
[sw2-Ethernet0/0/2]port default vlan 5
[sw2-Ethernet0/0/2]quit
[sw2]interface g0/0/2
[sw2-GigabitEthernet0/0/2]port link-type trunk
[sw2-GigabitEthernet0/0/2]port trunk allow-pass vlan all
[sw2-GigabitEthernet0/0/2]quit

3. 配置三层交换机

<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname sw3
[sw3]vlan batch 1 to 5
Info: This operation may take a few seconds. Please wait for a moment…done.
[sw3]interface g0/0/1
[sw3-GigabitEthernet0/0/1]port link-type trunk
[sw3-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[sw3-GigabitEthernet0/0/1]quit
[sw3]interface g0/0/2
[sw3-GigabitEthernet0/0/2]port link-type trunk
[sw3-GigabitEthernet0/0/2]port trunk allow-pass vlan all
[sw3-GigabitEthernet0/0/2]quit
[sw3]interface vlanif 1
[sw3-Vlanif1]ip address    
[sw3-Vlanif1]ip address 192.168.1.254 24
[sw3-Vlanif1]quit
[sw3]interface vlanif 2
[sw3-Vlanif2]ip address 192.168.2.254 24
[sw3-Vlanif2]quit
[sw3]interface vlanif 3
[sw3-Vlanif3]ip address 192.168.3.254 24
[sw3-Vlanif3]quit
[sw3]interface vlanif 4
[sw3-Vlanif4]ip address 192.168.4.254 24
[sw3-Vlanif4]quit
[sw3]interface vlanif 5
[sw3-Vlanif5]ip address 192.168.5.254 24
[sw3-Vlanif5]quit
[sw3]vlan 6
[sw3-vlan6]interface g0/0/3
[sw3-GigabitEthernet0/0/3]port link-type access
[sw3-GigabitEthernet0/0/3]port default vlan 6
[sw3-GigabitEthernet0/0/3]quit
[sw3]interface vlanif 6
[sw3-Vlanif6]ip address 192.168.6.254 24
[sw3-Vlanif6]quit
[sw3]ip route-static 192.168.7.0 255.255.255.0 192.168.6.1

4. 配置路由

<Huawei>system-view
Enter system view, return user view with Ctrl+Z.

[AR1-GigabitEthernet0/0/0]ip address 192.168.6.1 24
[AR1-GigabitEthernet0/0/0]quit
[AR1]interface g0/0/1
[AR1-GigabitEthernet0/0/1]ip address 192.168.7.254 24
[AR1-GigabitEthernet0/0/1]quit
[AR1]ip route-static 0.0.0.0 0.0.0.0 192.168.6.254
[AR1]quit
[AR1]display ip routing
