vrrp mstp 配置实验（学习笔记）

VRRP是一种容错协议，当主机的下一跳路由器出现故障时，由另一台路由器来代替出现故障的路由器进行工作，从而保持网络通信的连续性和可靠性。

MSTP：多生成树协议，通过生成多个生成树，来解决以太网环路问题，以及交换机负载

拓扑图：

具体配置步骤

1.在lsw1和lws2上基于接口划分vlan 10 20。

2.lsw3和lsw4交换机之间的链路聚合，并将接口类型配置为trunk，允许所以vlan通过。

3.在lsw3和lsw4上基于端口划分3个vlan，交换机之间接口用trunk，交换机与路由器之间用access，并配置ip地址。

4.在lsw3和lsw4上配置vrrp，配置虚拟地址和优先级。

5.在lsw3和lsw4上配置mstp，并设置实例，设置主根和词根

6.在lsw3，lsw4 ,R1上配置ospf 。

各设备的配置如下：
