前言

华为ensp小实验走起来。

一、题目及需求

要求按照拓扑图配置相关命令使得图中所有终端能够网络互通。
（1）MSTP+链路聚合：在SW1和SW2之间配置链路聚合，要求正常情况下有2条链路活跃、一条链路备份。常情况下各VLAN流量路径要求：VLAN10:SW3->SW2->R1；VLAN20:SW3->SW1->R1
（2）VRRP：正常情况下要求VLAN10的Master为SW2；VLAN20的Master为SW1
（3）DHCP：R3为DHCP中继代理，R2为DHCP服务器，为PC4、PC5提供动态分配IP服务。
（4）按照拓扑图中的要求在各三层交换机和路由器上配置路由，使得所有PC终端能够网络互通(10分)。
（5）NAT：使用EasyIp进行转换使得Client1能够使用R1的外网口IP访问外网；并使用NAT-Server使得Client1访问Server1的web服务时能够使用目标网址23.0.0.3/24的8080端口进行访问
