本例描述了P2MP TE隧道承载业务的配置过程。

组网需求

如图10-47所示，在VPLS Multi-homing的P2MP双根保护的场景中，PE1、PE2、PE3、PE4通过BGP Multi-homing方式建立VPLS网络，其中，PE1与PE3、PE4之间为主P2MP TE隧道，PE1为主根节点，PE2与PE3、PE4之间为备份P2MP隧道，PE2为备份根节点。组播源发两份流量，通过VPLS的Multi-homing功能，PE2的AC端口阻断，只有主根PE1收到一份流量，到达叶子节点后，发送给相应的接收端，接收端只收到一份流量。当PE1的AC接口故障或者是主P2MP TE隧道故障时，业务流量能够快速的切换到备份P2MP TE隧道上。

表10-9 设备接口及其对应的IP地址

设备	接口	IP地址
PE1	GE1/0/0	10.1.2.1/24
	GE 1/0/2	10.1.3.1/24
	GE 1/0/3	10.1.4.1/24
PE2	GE1/0/0	10.1.5.1/24
	GE 1/0/2	10.1.6.1/24
	GE 1/0/3	10.1.4.2/24
PE3	GE1/0/0	10.1.2.2/24
PE3	GE 1/0/2	10.1.6.2/24
PE4	GE1/0/0	10.1.5.2/24
PE4	GE1/0/2	10.1.3.2/24

配置思路

采用如下的思路配置P2MP TE隧道承载业务：

配置网络中设备各接口的IP地址和路由协议，实现各设备之间网络层互通。本示例配置OSPF路由协议。
在各设备上全局配置MPLS LSR-ID，全局使能MPLS、MPLS TE和P2MP TE能力。
在各节点配置LDP本地会话。
在PE1与PE3、PE1与PE4、PE2与PE3、PE2与PE4之间建立BGP Multi-homing方式的VPLS。
创建主、备P2MP TE隧道。
在PE3和PE4上配置叶子节点。

数据准备

为完成此配置例，需准备如下的数据：

网络中各设备接口的IP地址，具体数据参见表10-9。
各节点的OSPF进程号为100，区域标识为0.0.0.0。
PE1、PE2、PE3和PE4上的BGP AS号。
VSI实例的名称、VPLS ID、VPN-Target。
VSI绑定的接口编号。

操作步骤

配置网络中设备各接口的IP地址和路由协议，实现各设备之间网络层互通
具体配置过程请参见配置文件。
