配置虚拟集群接入VC接入L2VPN（多段PW）示例
本例描述了在IP RAN虚拟集群接入技术在IP RAN网络中承载TDM业务的基本配置过程。
组网需求
如图2-11所示，AP1为接入设备，负责连接基站，Master设备分为一主一备，在这三台设备上配置虚拟集群接入，配置完成后，将建立AP节点到Master节点的VP路径及VC连接，以承载基站传输过来的数据报文。现在需要让虚拟集群接入内部的设备与集群外设备互通并一起完成TDM业务的端到端承载。此时，可以在Master设备上配置虚拟集群接入VC接入L2VPN形成多段PW，达到上述目的。

配置思路
采用如下的思路配置虚拟集群接入VC接入L2VPN（多段PW）：
配置各节点接口的IP地址及作为管理IP的Loopback接口的地址。
使能Master和AP上全局和接口下虚拟集群接入的使能、配置各节点的管理IP以及AP所属的主备Master，以便完成虚拟集群接入的配置。
配置汇聚侧设备使用的IGP路由
在汇聚侧设备上配置LDP LSP隧道
在汇聚侧设备上配置VPWS PW，并在RSG1和RSG2之间配置Bypass PW
数据准备
为完成此配置例，需准备如下的数据：
各节点上直连接口的IP地址和Loopback接口的地址。
AP1所属的主Master是Master1，备份Master是Master2。
Master1节点上Remote-AP接口的编号为2，Master2上Remote-AP接口的编号为2。
操作步骤
- 配置各节点接口的IP地址及作为管理IP的Loopback接口的地址
配置各接口的IP地址和掩码，具体配置过程请参照配置文件。
- 使能Master和AP上全局和接口下虚拟集群接入的使能、配置各节点的管理IP以及AP所属的主备Master
具体配置过程请参照配置文件。
- 配置汇聚侧设备使用的IGP路由，以OSPF为例
具体配置过程请参照配置文件。
- 在汇聚侧设备上配置LDP LSP隧道

- 检查配置结果
配置完成后，在Master设备上执行display virtual-cluster-access vc命令，可以看到虚拟集群接入的VC状态为Up。以Master1为例：
[~Master1] display virtual-cluster-access vc -------------------------------------------------------------------------------- MasterID ApID State ApIF -------------------------------------------------------------------------------- 2.2.2.2 1.1.1.1 Up Serial0/1/0:1
在Master设备上执行display mpls l2vc命令，可以看到创建了LDP方式的VPWS PW连接。以Master1为例子：
