配置公网IPv6静态路由FRR示例

通过配置公网IPv6静态路由FRR，可以快速检查链路故障。

组网需求

如图4-6所示，在DeviceD上配置下一跳分别为DeviceA和DeviceB的两条IPv6静态路由，使链路B为链路A的备份。当链路A出现故障时，流量可以快速切换到链路B上。

图4-6 配置公网IPv6静态路由FRR组网图

本例中interface1，interface2，interface3，interface4和interface5分别代表GE 0/1/1，GE 0/1/2，GE 0/1/3，GE 0/2/3，GE 0/3/3。

配置注意事项

在配置过程中，需注意以下事项：

使能IPv6静态路由FRR时，到达同一目的地址至少有两条IPv6静态路由存在。

配置思路

采用如下的思路配置公网IPv6静态路由FRR：

在DeviceD上配置下一跳分别为DeviceA和DeviceB的两条IPv6静态路由。
在DeviceD上为链路A配置较高的Preference值，使系统优选链路A。
在DeviceD上使能IPv6静态路由FRR功能，查看备份出接口和备份下一跳的信息。
配置静态BFD for IPv6静态路由，已达到快速检测故障的目的。

为了达到快速检测故障的目的，建议配置动态BFD for IPv6静态路由或配置静态BFD for IPv6静态路由。在现网中比较常用的是静态BFD for IPv6静态路由，因此本示例采用静态BFD for IPv6静态路由。
IPv6静态路由FRR去使能后，查看备份出接口和备份下一跳的信息。

数据准备

为完成此配置例，需准备如下的数据：

IPv6静态路由的Preference值。

操作步骤

配置各接口的IP地址，请参见配置文件
