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

如图1所示，在MPLS骨干网中，从Router A到Router C建立MPLS TE隧道Primary LSP，由Router D到Router 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。

图1 MSR系列路由器MPLS TE双向链路保护FRR功能配置组网图

设备	接口	IP地址	设备	接口	IP地址
Router A	Loop0	1.1.1.1/32	Router B	Loop0	2.2.2.2/32
	Eth0/1	192.168.1.1/24		Eth0/1	1.0.0.2/24
	Eth0/2	3.0.0.1/24		Eth0/2	2.0.0.1/24
	Eth0/3	1.0.0.1/24	Router D	Loop0	4.4.4.4/32
Router C	Loop0	3.3.3.3/32		Eth0/1	192.168.1.2/24
	Eth0/1	192.168.2.1/24	Router E	Loop0	5.5.5.5/32
	Eth0/2	3.0.0.2/24		Eth0/1	192.168.2.2/24
	Eth0/3	2.0.0.2/24

 

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。

3.3  使用版本

本举例是在Release 2311版本上进行配置和验证的。
