1、实验要求：

2、实验拓扑

3、分析过程

1、创建eth-trunk，VLAN
2、将接口划入对应的VLAN
3、trunk干道
4、选择生成树类型并定义事件
5、对生成树进行干预，达到实验最优根
6、配置svi接口
7、VRRP配置
8、dhcp

4、配置内容

1、创建eth-trunk，VLAN
2、将接口划入对应的VLAN
3、trunk干道
4、选择生成树类型并定义事件

[sw1]stp enable
[sw1]stp mode mstp
[sw1]stp region-configuration
[sw1-mst-region]region-name a
[sw1-mst-region]instance 1 vlan 1  --定义事件1
[sw1-mst-region]instance 2 vlan 2  --定义事件2
[sw1-mst-region]active region-configuration
[sw1-mst-region]q
[sw1]stp instance 1 root primary   --定义事件1的主根
[sw1]stp instance 2 root secondary  --定义事件2的备用根

5、对生成树进行干预，达到实验最优根

[sw1]stp instance 1 root primary   --定义事件1的主根
[sw1]stp instance 2 root secondary  --定义事件2的备用根

6、配置svi接口

[sw1]int vlan1
[sw1-Vlanif1]ip add 172.16.1.1 25
[sw1-Vlanif1]q
[sw1]int vlan 2

7、VRRP配置

[sw1]int vlanif 1  --在vlanif1  vrrp
[sw1-Vlanif1]vrrp vrid 1 virtual-ip 172.16.1.126
[sw1-Vlanif1]vrrp vrid 1 priority 105
[sw1-Vlanif1]vrrp vrid 1 track interface Ethernet 0/0/1 reduced 6
[sw1-Vlanif1]q

8、dhcp
