1.BFD
配置双向转发检测(Bidirectional Forwarding Deteletion,BFD)实现链路故障快速检测和静态路由的自动切换。
以R3为例配置R3和R2之间的BFD会话
[R3]BFD
[R3-bfd] quit
[R3]bfd 1 bind peer-ip 10.23.0.1 source-ip 10.23.0.3 auto
[R3-bfd-session-1]commit
[R3-bfd-session-1]quit
\\配置去往服务器网段的浮动静态路由,优先选择经R1路由器转发,而将经R3路由器转发作为备份链路
[R2]ip route-static 10.2.2.0 0.255.255.255 10.12.0.1
[R2]ip route-static 10.2.2.0 0.255.255.255 10.23.0.3 preference 100
