配置单跳PW的PWE3 Trace测试示例
组网需求
如图6-53所示。CE-A、CE-B分别通过VLAN方式接入PE-A和PE-B。PE-A和PE-B用MPLS骨干网连接。在PE-A和PE-B之间使用LSP隧道建立动态PW。
使用单跳PW的PWE3 Trace功能测试PE-A与PE-B之间的PW连通性状态。
配置思路
采用如下思路进行配置：
在骨干网上运行IGP路由协议，使骨干网各Switch能互通。
在骨干网上配置MPLS基本能力，建立LSP隧道。且PW两端的PE之间要建立MPLS LDP远端对等体关系。
在PE上创建MPLS L2VC连接。
在PE-A上配置单跳PW的PWE3 Trace测试例。
操作步骤
- 配置单跳动态PW。
在MPLS骨干网上配置单跳动态PW。具体配置过程请参见《S9300, S9300X V200R019C10 配置指南-VPN》 PWE3配置。
- 配置单跳PW的PWE3 Trace测试例。
# 配置PE-A。
<Quidway> system-view [Quidway] sysname PE-A [PE-A] nqa test-instance test pwe3trace [PE-A-nqa-test-pwe3trace] test-type pwe3trace [PE-A-nqa-test-pwe3trace] local-pw-type vlan [PE-A-nqa-test-pwe3trace] local-pw-id 100
- 启动测试操作。
[PE-A-nqa-test-pwe3trace] start now
- 验证测试结果。
在PE上执行display nqa history命令，可以看到相应状态为成功。

在PE上执行display nqa results命令，可以看到测试结果为成功。
