一、实验要求：

二、配置思路：

1）拓扑设计，IP地址规划

基于172.16.0.0/16划分：

172.16.0.0/24用于骨干 --172.16.0.0/30 172.16.0.4/30

172.16.1.0/24用于用户--vlan 1:172.16.1.0/25 vlan 2:172.16.1.128/25

2)拓扑搭建

3）配置流程

Eth trunk-->创建VLAN-->划入VLAN-->trunk干道-->STP-->SVI-->VRRP-->DHCP

三、配置

1.SW1 SW2直接起Eth trunk:

[SW2]interface Eth-Trunk 0
[SW2-Eth-Trunk0]q

[SW2]interface g0/0/2 接口划入eth trunk
[SW2-GigabitEthernet0/0/2]eth-trunk 0

[SW2]interface g0/0/3 接口划入eth trunk
[SW2-GigabitEthernet0/0/3]eth-trunk 0

2.SW1 SW2 SW3 SW4创建vlan，只需创建vlan2，默认为vlan1。

[SW3]interface Ethernet 0/0/2
[SW3-Ethernet0/0/2]port link-type access

[SW3-Ethernet0/0/2]port default vlan 2

3.trunk干道，每台交换机的接口均配置，除上行链路。

[SW2]port-group group-member g0/0/1 g0/0/4 Eth-Trunk 0 以组划分
[SW2-port-group]port link-type trunk
[SW2-GigabitEthernet0/0/1]port link-type trunk
[SW2-GigabitEthernet0/0/4]port link-type trunk
[SW2-Eth-Trunk0]port link-type trunk

[SW2-port-group]port trunk allow-pass vlan 2
[SW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 2
[SW2-GigabitEthernet0/0/4]port trunk allow-pass vlan 2
[SW2-Eth-Trunk0]port trunk allow-pass vlan 2
[SW2-port-group]q

4.STP的配置

[SW2]stp mode mstp
[SW2]stp enable
[SW2]stp region-configuration
[SW2-mst-region]instance 1 vlan 1
[SW2-mst-region]instance 2 vlan 2
[SW2-mst-region]active region-configuration

[SW2]stp instance 1 root secondary

[SW2]stp instance 2 root primary

5.SVI配置

[SW2]interface vlan 1
[SW2-Vlanif1]ip address 172.16.1.2 25

[SW2]interface vlan 2

[SW2-Vlanif2]ip address 172.16.1.130 25

6.VRRP配置：在SW2上，vlan2为主，vlan1为辅；反之，在SW1上vlan1为主，vlan2为辅。

[SW2]interface vlan 2
[SW2-Vlanif2]vrrp vrid 1 virtual-ip 172.16.1.254

[SW2-Vlanif2]vrrp vrid 1 priority 105

[SW2-Vlanif2]vrrp vrid 1 track interface g0/0/5 reduced 6

[SW2]interface vlan 1
[SW2-Vlanif1]vrrp vrid 1 virtual-ip 172.16.1.126
[SW2-Vlanif1]q

7.DHCP配置
