华为设备stp、vrrp的实力应用

实验拓扑：

实验目的：1.熟练地应用stp、vrrp的应用及配置

          2.了解环路以及解决方案

          3.使全网互通

实验思路：首先把拓扑图分为三个部分

          1.配置相同vlan相通，相同网段看交换，先配置交换机，左右两边各有三个交换机，所有会有环路，就要用到stp ，把sw2，3配置为根网桥，所有交换流量都要通过他俩：    配置命令：stp root primary

其他两个交换机配置stp，实现负载均衡，以及备份链路

  [sw]stp region-configuration

[sw-mst-region]region-name haha

[sw-mst-region]instance 1 vlan 10 

[sw-mst-region]instance 2 vlan 20     

[sw-mst-region]active region-configuration

[sw]stp instance 1 priority 4096

[sw]stp instance 2 priority 8192

交换机与交换机之间用trunk链接

2. 在配置第二部分，不同网段用路由。

 三个路由器都要使用的情况下，要实现冗余，就用vrrp协议配置优先级

配置命令：

R1

vrrp vrid 10 virtual-ip 192.168.10.250 创建虚拟网关

vrrp vrid 10 priority 150    配置优先级为150，默认100

vrrp vrid10 interface gi 0/0/2 reduce 100 

配置链路跟踪，当interface gi0/0/2 端口为down时，优先级减100

 R2

vrrp vrid 10 virtual-ip 192.168.10.250

vrrp vrid 10 priority 100

R3

vrrp vrid 10 virtual-ip 192.168.10.250

vrrp vrid 10 priority 80

3.配置第三部分

 交换机端口开启
