HCIE必考题：HUB Spoke实验
HCIE必考的一个lab题，可以添加微信 领取实验压缩包和实验图。（微信号：taige8080）多的不说了，直接上图和配置文件。
太真实了，自己敲过才知道，会错在什么地方。
BGP中：
Ipv4单播邻居跑公网路由
VPNv4 跑穿透路由
Vpnv4 instance和客户CE建立邻居传递私网路由。
VPN-IPv4地址结构
图片
RD（route distinguisher）：64bits，用于区分使用相同地址空间的IPv4前缀，增加了RD的IPv4地址称为VPN-IPv4地址（即VPNv4地址）。PE从CE接收到IPv4路由后，转换为全局唯一的VPN-IPv4路，并在公网上发布。
RD的两个功能：
1) 与 32bits 的 Ipv4 前缀一起构成 96bits 的 VPNv4 前缀；
2) 如果不同的 VPN 客户，存在相同的 IPv4 地址空间，那么可以通过设置不同的 RD 值从而保证前缀的唯一性。
• 每一个VRF有一个全局唯一的RD。
• 同一个VPN的不同站点可以配置相同的RD，不同VPN的RD必须唯一。
RT（Route Target）：用来区分VPN customer ，是BGP community 的扩展属性，在VRF 中进行配置。它跟在VPNv4 前缀后面被一起传递。一条路由可以附加多个RT 值。
有两类VPN Target属性：
• Export Target：本地PE从直接相连Site学到IPv4路由后，转换为VPN-IPv4路由，并为这些路由设置Export Target属性。Export Target属性作为BGP的扩展团体属性随路由发布。
• Import Target：PE收到其它PE发布的VPN-IPv4路由时，检查其Export Target属性。当此属性与PE上某个VPN实例的Import Target匹配时，PE就把路由加入到该VPN实例中。
在BGP/MPLS IP VPN网络中，通过VPNTarget属性来控制VPN路由信息在各Site之间的发布和接收。VPN Export Target和ImportTarget的设置相互独立，并且都可以设置多个值，能够实现灵活的VPN访问控制，从而实现多种VPN组网方案。
