通过配置BGP方式VPLS和LDP方式VPLS interworking示例，可以实现BGP方式VPLS和LDP方式VPLS的对接。

组网需求

如图10-24，PE1和SPE之间部署LDP方式VPLS，SPE、PE2、PE3之间部署BGP方式VPLS。为实现CE1、CE2和CE3设备之间的互通，需要在LDP方式VPLS和BGP方式VPLS之间的边缘节点SPE上部署混合VSI，在此VSI实例下创建LDP信令和BGP信令。

图10-24 配置BGP VPLS和LDP VPLS interworking示例

本示例中interface1，subinterface1.1，inerface2，inerface3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VPLS的基本功能：

在骨干网上配置路由协议实现互通，并配置MPLS基本能力。
在PE和SPE之间建立LSP隧道。
在PE和SPE上使能MPLS L2VPN。
在PE和SPE上使能BGP对等体交换VPLS信息的能力。
在SPE上配置混合VSI实例
将AC接口与VSI进行绑定。

数据准备

为完成此配置例，需准备如下的数据：

对等体的IP地址。
VSI实例的名称
绑定VSI的接口和接口上封装的VLAN ID值。

操作步骤

配置各设备的IP地址。

验证配置结果

完成上述配置后，执行display vpls connection命令，可以看到建立的VPLS状态为up。以SPE的配置为例：

[~SPE] display vpls connection

3 total connections,
connections: 3 up, 0 down, 1 ldp, 2 bgp, 0 bgpad

执行display vsi name vsi1 verbose命令，可以看到名字为bgp1的VSI建立了的PW，VSI状态为UP。以SPE的配置为例：
