H3CNE综合实验机器人
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 Van20:Vlan10 是市场部，Van20 是技术部，要求对 Vlana 进行命名以便识别: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
4.所有交换机相连的端口配置为 Trunk，允许相关流量通过
5.交换机连接 PC 的端口配置为边缘端口
6.在 SW1 上配置 DHCP 服务，为 Van10 和 Van20 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
7.按图示分区域配置 OSPF 实现公司内部网络全网互通，ABR 的环回口宣告进骨干区域:业务网段不允许出现协议报文
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 PPP-MP，并配置双向 chap 验证
10.配置 EASY IP，只有业务网段 和 的数据流可以通过 R1 访问互联网192.168.1.0/24 192.168.2.0/2411.R1 开启 11.TELNET 远程管理，使用用户ikun登录，密码 123456abc，只允许技术部远程管理 R1
