MPLS实验

设计思路：
第一阶段 路由通信
第一步：
创建 VRF 定义RT RD
接口划入VRF
12 运行动态协议 45 之间相同做法 eigrp 需要声明
2 4 BGP
MP–BGP （VPNv4–BGP）
动态路由重发布 BGP 识别RT BGP重发布到 5
双层标签
客户和运营商的边界路由器启动相应的路由协议，然后在PE路由器的路由表下 创建多个虚拟路由表（VRF）并创建一个标识RD值 （为了区分不同的客户之间将路由重发布到主运营商的路由表中，IP地址 可能会出现相同的） ；
第二步： VPNv4路由（传递IPV6的路由为VPNv6路由） 重发布到主路由表中， 则主网络中必须开启BGP邻居 ； 2 4 之间必须建立 BGP邻居 和VPNv4的邻居 中间的路由器例如 3 不需要考虑 （BGP传递路由使用单播，TCP三次握手）；
第三步 由于 RD VRF 只具有本地意义，所以需要 RT值；RT值重发布到BGP中，变成扩展团体属性携带在路由中；从而路由导入和导出只能进入RT值相同的VRF中;
第四步
4 5 之间建立IGP协议 将4中的BGP路由表与5中VRF的RT值相同的路由重发布到5中。
