配置CE非对称接入3PE的PW Redundancy示例（移动承载组网）
在CE非对称接入3PE的PW Redundancy场景中，E-Trunk确定PE的主备关系。
组网需求
如图9-33所示，CE1和CE2属于同一个企业用户，CE1单归接入公网设备PE1，CE2通过Eth-Trunk双归接入公网设备PE2和PE3。为了满足CE1与CE2之间互通并保证可靠性的要求，PE1与PE2、PE3之间通过PW Redundancy模式提供PW保护。为了提高公网链路故障的快速检测，实现PW的快速切换，需要部署BFD检测公网链路故障。
配置思路
采用如下的思路配置CE非对称接入3PE的PW Redundancy：
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。
配置MPLS和公网隧道。
配置业务PW和管理PW，并将业务PW和管理PW绑定。
配置BFD检测管理PW。
配置E-Trunk，协商PW主备关系；并配置BFD和E-Trunk绑定。
数据准备
为完成此配置例，需准备如下的数据：
PE接口编号、接口IP地址和OSPF进程号
PE的LSR ID
E-Trunk的LACP系统ID和优先级
L2VC的目的地址、VC ID和VC Type
BFD会话的名称、本地标识符、远端识别符
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。
- 配置MPLS基本功能。配置PE1和PE2之间、PE1和PE3之间的TE隧道，配置PE2和PE3之间的LDP-LSP隧道。
具体配置过程请参见配置文件。
- 配置PWE3
- 配置PE1和PE2之间、PE1和PE3之间的MPLS LDP远端会话。
具体配置过程请参见配置文件。
因为PE1和PE2之间、PE1和PE3之间是TE隧道，没有配置MPLS LDP，但是PWE3使用扩展的LDP信令分配私网标签，所以此处需要配置MPLS LDP远端会话。
因为PE2和PE3之间已经是LDP-LSP隧道，且是直连的，所以不用配置LDP远端会话。
- 配置PE1和PE2之间、PE1和PE3之间的MPLS LDP远端会话。
- 配置BFD会话检测管理PW
# 配置PE1。

PE2和PE1之间的公网链路故障
# 关闭PE2的GE1/0/0接口，模拟主用PW故障。本步骤仅为验证配置效果所用，实际配置中请不要这样操作。[~PE2] interface gigabitethernet 1/0/0

此时由于主用PW故障，在PE1上执行命令display mpls l2vc，可以看到PE1与PE2之间的管理PW和业务PW的VC状态为down，PE1与PE3之间的管理PW和业务PW的VC状态为up。

[*PE2] commit此时主用PW所在链路虽然故障恢复，但是主用PW需要一定时间协商建立，此时流量仍然走备份PW。待主用PW协商建立成功后，在PE1上执行命令display mpls l2vc，可以看到PE1与PE2之间的管理PW和业务PW的VC状态变为up。
