配置多跳PW的PWE3 Ping测试示例
组网需求
如图6-52所示。CE-A、CE-B分别通过VLAN方式接入U-PE1和U-PE2。U-PE1和U-PE2通过MPLS骨干网连接。使用LSP隧道，并以S-PE作为交换节点，在U-PE1和U-PE2之间建立多跳动态PW。
使用多跳PW的PWE3 Ping功能测试U-PE1与U-PE2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。U-PE1与S-PE之间、U-PE2与S-PE之间需建立MPLS LDP远端对等体关系。
U-PE之间创建MPLS L2VC连接。
在交换节点S-PE上创建交换PW。
在U-PE1上配置多跳PW的PWE3 Ping测试例。
操作步骤
- 配置多跳动态PW。
在MPLS骨干网上配置多跳纯动态PW。具体配置过程请参见《S9300, S9300X V200R019C10 配置指南-VPN》 PWE3配置。
- 配置多跳PW的PWE3 Ping测试例。
# 配置U-PE1。
<Quidway> system-view [Quidway] sysname U-PE1 [U-PE1] nqa test-instance test pwe3ping [U-PE1-nqa-test-pwe3ping] test-type pwe3ping [U-PE1-nqa-test-pwe3ping] local-pw-id 100 [U-PE1-nqa-test-pwe3ping] local-pw-type vlan [U-PE1-nqa-test-pwe3ping] label-type control-word [U-PE1-nqa-test-pwe3ping] remote-pw-id 200
- 启动测试操作。
[U-PE1-nqa-test-pwe3ping] start now
- 验证测试结果。
在PE上执行display nqa results命令，可以看到测试结果为成功。
