NE综合实验3

链路聚合：通过LACP或静态聚合提升带宽与冗余性
VLAN与Trunk：跨交换机VLAN通信及Trunk端口配置
STP：生成树协议优化网络拓扑防环
DHCP：动态地址分配与中继配置
OSPF：动态路由协议实现多区域互联
默认路由：边界设备外网流量引导
PPP：广域网链路认证与封装

一、实验拓扑

请添加图片描述

二、实验需求

IP地址配置如图，公司网络通过R1连接互联网
SW1和SW2之间的直连链路配置链路聚合
公司内部业务网段为vlan10和vlan20；PC1属于vlan10，PC2属于vlan20，vlan30用于SW1和SW2建立OSPF邻居；vlan111为SW1和R1的互联vlan，vlan222为SW2和R2的互联vlan
所有交换机相连的端口配置为trunk，不允许无关流量通过
交换区域配置生成树，要求SW2为根网桥，闭塞端口在SW3上
交换机连接PC的端口配置为边缘端口
在SW1配置DHCP服务，为vlan10和vlan20的PC动态分配IP地址、网关和DNS地址；要求vlan10的网关是192.168.1.252，vlan20的网关是192.168.2.253
按图示分区域配置OSPF实现公司内部网络全网互通，R1和R2的环回口宣告进骨干区域；业务网段不允许出现协议报文（即配置静默接口）
R1上配置默认路由指向互联网，并引入到OSPF
R1通过双线连接到互联网，配置MP-GROUP，并配置双向chap验证
只有业务网段192.168.1.0/24和192.168.2.0/24的数据流可以通过R1访问互联网
R1开启TELNET远程管理
