一、实验题目
实验要求：
1，内网IP地址172.16.0.0/16合理分配
2，SW1/2之间互为备份
3，VRRP/STP/VLAN/TRUNK均使用
4，所有PC通过DHCP获取IP地址
二、实验思路
2.1 拓扑设计（IP地址规划）
内网依据172.16.0.0/16划分，使用172.16.0.0/24即可，两个骨干链路172.16.0.0/30 172.16.0.4/30
vlan1：172.16.1.0/25 vlan2：172.16.1.128/25
R1-R2网段：12.1.1.0/24 LSP环回：1.1.1.0/24
2.2 实施
拓扑的搭建
配置
交换---拓扑搭建
底层---所有节点拥有合法IP地址
路由---全网可达
策略（优化，规则，安全）
测试
排错
2.3 维护
2.4 升级
涉及知识点：
交换---eth-trunk STP SVI vlan（创建、划分） trunk DHCP VRRP（网关冗余）
配置顺序:
eth-trunk 创建vlan、划分vlan trunk STP SVI VRRP DHCP
