H3CNE综合实验之机器人
实验拓扑图
实验需求
1.按照图示配置 IP 地址
2.SW1 和 SW2 之间的直连链路配置链路聚合
3.公司内部业务网段为 Vlan10 和 Vlan20;Vlan10 是市场部，Vlan20 是技术部，要求对 Vlan 进行命名以识别;
PC8 属于 Vlan10，PC9 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
4.所有交换机相连的端口配置为 Trunk，允许相关流量通过
5.交换区域配置生成树，要求SW2为根网桥，闭塞端口在SW3上
6.交换机连接 PC 的端口配置为边缘端口
7.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）
8.R1 上配置默认路由指向互联网，并引入到 OSPF
9.R1通过双线连接到互联网，配置MP-GROUP，并配置双向chap验证
10.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
11.R1开启TELNET远程管理，使用用户abc登录，密码123456.com
1.按照图示配置 IP 地址（略）
