路由和交换在运营商网络的综合实验

测试结果

---

 要求：

1、按照拓扑图规划网络；
2、实现网络全网互通，总部实现默认路由下发，降低设备要求；
3、二层网络实现流量负载分担；
4、总部网络终端实现网关冗余备份，且实现上行链路监控；
5、总部网络终端主机使用dhcp获得ip；
6、总部网络汇聚层实现链路聚合(动态，最大链路数5条，可激活3条)；
7、分部终端要尽快进入转发状态，且上下线不会造成网络震荡；MSTP
8、总部vlan 10之间不能互相访问，vlan 20之间可互相访问。端口隔离

9 ，PC 2 3 4 DHCP 获取地址

注：1 由于是运营商网络 在LSP中不能出现私网ip因此 vlan 10 20 30 40 使用 MPLS VPN 隧道连接

        2 接口绑定实例后接口已有的配置会自动删除 因此先接入实例后配置地址

        3 先创建Eth-trunk 组并在端口加入，后配置三层交换机 

        4 在SW1 SW2 创建接口下DHCP  

配置思路

1 LSP骨干网ospf 联通R1 R2 R3
2 开启 R1 R2 R3 mpls ldp
3 创建 R2 R3 VPN 实例
4 接口绑定 VPN 实例
5 配置接口地址
6 配置MPLS VPN 用户接入 
7 在配置 vlan 10 20 30 40 时一并配置 VRRP 和 链路聚合 
8 测试 排错

已给配置
