HCIP-5.6 VRRP联动BFD

1.当主设备R1上连故障时，心跳报文抑制正常，不会切换

R2一直是Backup状态，此时无法和Internet通信

跟踪上连接口 track

int g0/0/1
 vrrp vrid 1 track intface g0/0/1 reduced 15 #被跟踪接口故障，优先级自定义减15。缺省自动减10

VRRP联动BFD

[R1]bfd
     bfd aa bind peer-ip 12.1.1.2 source-ip 12.1.1.1 auto
     commit

Internet路由Router

[Router]bfd
         bfd aa bind peer-ip 12.1.1.1 source-ip 12.1.1.2 auto

VRRP调用BFD

int g0/0/0
 vrrp vrid 1 track bfd-session session-name aa   # aa bfd会话名称

检测到bfd-session down之后会减优先级，缺省减10

dis bfd session dynamic
