一端CE单归接入到PE上，另一端CE双归接入到另一台PE上，通过配置CE非对称接入BGP方式的VPWS FRR，实现CE之间的互通。

组网需求

如图9-32所示，CE1单归接入PE1，CE2双归接入PE2和PE3，PE1和PE2之间配置主用BGP方式VPWS，PE1和PE3之间配置备用BGP方式VPWS，因此主用路径为：CE1->PE1->PE2->CE2。当主用路径发生故障时，VPWS的流量能够快速切换到备份路径CE1->PE1->PE3->CE2上。

图9-32 配置BGP方式VPWS FRR示例组网图-CE非对称接入

本示例中interface1，sub-interface1.1，inerface2，interface3分别代表GE1/0/0，GE1/0/0.1，GE2/0/0，GE3/0/0。

配置思路

采用如下的思路配置BGP方式VPWS FRR示例-CE对称接入的基本功能：

在骨干网相关设备上配置路由协议实现互通，并使能MPLS基本功能和LDP功能。
使能BGP对等体交换VPWS的功能。
在PE上使能MPLS L2VPN功能，并创建一条CE1到CE2的BGP方式VPWS远程连接。
在PE2、PE3上配置AC OAM检测和通告功能，并使能OAM Mapping功能。

数据准备

为完成此配置例，需准备如下的数据：

BGP的AS号。
PE上MPLS-L2VPN实例名。
PE上MPLS-L2VPN实例的RD、VPN-Target。
在PE上需要配置的CE名称及ID。
