eNSP下园区网综合实验分步配置（2）MSTP、VRRP、BFD
MSTP配置：
//所有核心、汇聚设备及服务器交换机（SW1、SW2、SW3、SW4、SW8）都做如下命令，接入层设备可以不做。
[SW]stp region-configuration
[SW-mst-region]region-name A //mst域的名称
[SW-mst-region]revision-level 1 //修订号为1
[SW-mst-region]instance 1 vlan 2 3 200 //将vlan 2 3 200映射到实例1
[SW-mst-region]instance 2 vlan 4 5 //将vlan 4 5映射到实例2
[SW-mst-region]active region-configuration //激活配置
----------------
SW1（核心）：
[HeXin-SW1]stp instance 1 root primary //该设备成为实例1的根桥
[HeXin-SW1]stp instance 2 root secondary //该设备成为实例2的备份根桥
SW2（核心）：
[HeXin-SW2]stp instance 2 root primary
[HeXin-SW2]stp instance 1 root secondary

STP优化：
边缘端口配置：

[JieRu-SW5-Ethernet0/0/2]stp edged-port enable
SW6（接入）：
[JieRu-SW6]int Ethernet 0/0/3

SW7（接入）：
[JieRu-SW7]int Ethernet0/0/1
[JieRu-SW7-Ethernet0/0/1]stp edged-port enable
[JieRu-SW7-Ethernet0/0/1]qu
[JieRu-SW7]int eth

[SW8-Ethernet0/0/3]stp edged-port enable
[SW8-Ethernet0/0/3]qu
[SW8]int Ethernet0/0/4
[SW8-Ethernet0/0/4]stp edged-port enable
[SW8-Ethernet0/0/4]qu取消核心设备上联口的STP功能：
该接口的Down及Up不影响生成树计算（该接口也不会产生环路）。
