本文介绍了通过MPLS L3VPN技术提供VPN服务的典型配置举例。
本文档中的配置均是在实验室环境下进行的配置和验证,配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置,为了保证配置效果,请确认现有配置和以下举例中的配置不冲突。
本文档假设您已了解MPLS L3VPN特性。
如图1所示,Customer A和Customer B分别有位于两地的分支机构,现要求通过MPLS L3VPN技术,实现用户分支机构间路由信息的正常交互,且用户数据可以通过VPN方式在各站点间安全传输,不会发送至私网IP地址相同的其它用户站点中。
图1 MPLS L3VPN基本组网图
· 为了使报文能够通过MPLS网络传输,需要在MPLS骨干网络中配置IGP路由协议,并利用LDP分发公网标签,作为VPN报文的外层标签。
· 为区分不同用户的路由信息,需要在PE上分别创建两个VPN实例,并为VPN实例配置RD和RT,在各实例内通过BGP分别引入不同用户的私网路由。
· 在PE设备之间配置MP-BGP协议并建立对等体,用于传输VPN的私网路由信息并分发内层标签,即私网标签。
由于在配置接口与VPN实例绑定后,接口上的IP地址等配置会清除,因此先配置接口与VPN实例的绑定关系,再进行其他配置。
(1) 配置PE 1
# 配置骨干网接口以及环回口地址。
<PE1> system-view
[PE1] interface loopback 0
[PE1-LoopBack0] ip address 1.1.1.9 32

配置完成后,PE 1、P、PE 2之间应能建立OSPF邻居,执行display ospf peer命令可以看到邻居达到Full状态。执行display ip routing-table命令可以看到PE之间学习到对方的Loopback路由。
