目标

配置静态BFD for IP会话

组网模型

配置思路

• 进入BFD视图

• 配置静态bfd for ip

• 配置本端标识符和远端标识符

操作步骤

1. 配置各接口IP地址（略）
2. 全局使能BFD功能

配置CX1

CX1:
bfd

配置CX2

CX2:
bfd

1. 配置静态BFD for IP

配置CX1

CX1:
bfd cx1-cx2 bind peer-ip 10.1.1.2 source-ip 10.1.1.1

配置CX2

CX2:
bfd cx2-cx1 bind peer-ip 10.1.1.1 source-ip 10.1.1.2

1. 配置本端标识符和远端标识符

配置CX1

CX1:
bfd cx1-cx2 bind peer-ip 10.1.1.2 source-ip 10.1.1.1
 discriminator local 80
 discriminator remote 100

配置CX2

CX2:
bfd cx2-cx1 bind peer-ip 10.1.1.1 source-ip 10.1.1.2
 discriminator local 100
 discriminator remote 80

1. 配置验证
