1  简介

本文档介绍使用MPLS TE双向链路保护FRR功能的典型案例。

2  配置前提

本文档不严格与具体软、硬件版本对应,如果使用过程中与产品实际情况有差异,请参考相关产品手册,或以设备实际情况为准。

本文档中的配置均是在实验室环境下进行的配置和验证,配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置,为了保证配置效果,请确认现有配置和以下举例中的配置不冲突。

本文档假设您已了解MPLS TE的FRR功能特性。

3  配置举例

3.1  组网需求

图1所示,MPLS骨干网中,从Router ARouter C建立MPLS TE隧道Primary LSP,由Router DRouter E的报文优先选择Primary LSP进行转发。要求:

·     建立一条备份MPLS TE隧道Bypass LSP,当Primary LSP中断时,自动快速重路由到备份隧道Bypass LSP

·     MPLS TE隧道使用显式路径方式。

3.2  配置思路

为了使数据报文在Primary LSP中断后快速重路由到Bypass LSP,需要将Bypass LSP绑定到被保护的接口,使得被保护接口中断时触发Bypass LSP

在配置MPLS TE隧道时,由于MPLS TE的LSP隧道是单向的,因此需要在Router A和Router C都向对方建立LSP,只有双向LSP都建立成功,发送给对方的报文才能正常转发回来。
