华为三层架构实验

拓扑图如上，该实验需要实现LSW3和LSW4互为vlan2和vlan3的主网关，且做到热机互备，另外需要实现vlan2通过R1去AR1，vlan3通过R2去AR1。

一、二层配置

1.vlan的创建及将接口划入相应的vlan

LSW1

vlan batch 2 to 3

interface GigabitEthernet0/0/3
[s1-GigabitEthernet0/0/3] port link-type access
 port default vlan 2
 stp edged-port enable

interface GigabitEthernet0/0/4
[s1-GigabitEthernet0/0/3] port link-type access
 port default vlan 3
 stp edged-port enable

LSW2

interface GigabitEthernet0/0/3
[s1-GigabitEthernet0/0/3] port link-type access
 port default vlan 2
 stp edged-port enable

interface GigabitEthernet0/0/4
[s1-GigabitEthernet0/0/3] port link-type access
 port default vlan 3
 stp edged-port enable

2.干道及链路聚合

[s1]interface g0/0/1

port link-type trunk
port trunk allow-pass vlan 2 to 3

[s1]interface g0/0/2

port link-type trunk
port trunk allow-pass vlan 2 to 3

[s2]interface g0/0/1

port link-type trunk
port trunk allow-pass vlan 2 to 3

[s2]interface g0/0/2

port link-type trunk
port trunk allow-pass vlan 2 to 3

LSW3

[s3]interface Eth-Trunk 0
[s3-Eth-Trunk0]trunkport g0/0/1

[s3-Eth-Trunk0]trunkport g0/0/2

 port link-type trunk
