   • 3.1. MSTP简介

MSTP（多生成树协议）是在STP的基础上发展而来的，用于在局域网中消除数据链路层的物理环路，作为一种二层协议，MSTP通过选择性的阻塞网络中的冗余链路来消除二层环路，将环路网络结构修剪无环路的树型网络结构，从而防止在环路网络中不断增生和无限循环，避免设备由于重复接收相同报文造成报文处理能力的下降；同时，它还具备链路备份的能力。与STP相比，MSTP可以实现网络拓扑的快速收敛，也能使不同VLAN的流量沿各自的路径转发，从而为冗余链路提供了更好的负载分担机制。
• 3.2. VRRP简介

VRRP用来为网关设备提供冗余备份。VRRP将可以承担网关功能的一组设备加入到备份组中，形成一台虚拟路由器，局域网内的主机将此虚拟路由器设置为缺省网关。VRRP根据优先级从备份组中选举一台网关设备作为Master，负责转发局域网内主机与外部通信的流量，其他网关设备作为Backup。当Master出现故障后，VRRP重新选举新的Master，保证流量转发不会中断。

5.3. 步骤总结
MSTP+VRRP配置步骤
1、配置交换机的基本配置，例如接口信息、主机名等
2、配置交换机聚合链路为samartgroup1
3、配置主VRRP ID、虚拟IP、优先级，然后设置备VRRP的虚拟IP、优先级（此处的优先级一定要比主设备的低）
4、配置MSTP，进入MSTP配置接口、配置name、实例映射、激活，退出后设置主备
5、配置完成
