BFD配置三层物理链路单跳检测
组网需求如图6-23所示,RouterA和RouterB之间通过三层物理链路直连。用户希望可以实现设备间链路故障的快速检测。图6-23配置三层物理链路单跳检测组网图https://download.huawei.com/mdl/image/download?uuid=e80b08795a4c421cbf4743f907b0e7f1
配置思路采用如下思路配置BFD单跳检测:在RouterA和RouterB上分别配置BFD会话,实现RouterA和RouterB间链路的检测。
操作步骤配置RouterA和RouterB的直连接口IP地址# 配置RouterA的接口IP地址。
<Huawei> system-view sysname RouterA interface gigabitethernet 1/0/0 ip address 10.1.1.1 24 quit# 配置RouterB的接口IP地址。
<Huawei> system-view sysname RouterB interface gigabitethernet 1/0/0 ip address 10.1.1.2 24 quit配置BFD单跳检测# 在RouterA上使能BFD,并配置与RouterB之间的BFD Session。需要在BFD Session中绑定接口。
bfd quit bfd atob bind peer-ip 10.1.1.2 interface gigabitethernet 1/0/0 discriminator local 1 discriminator remote 2 commit quit# 在RouterB上使能BFD,并配置与RouterA之间的BFD Session。需要在BFD Session中绑定接口。
bfd quit bfd btoa bind peer-ip 10.1.1.1 interface gigabitethernet 1/0/0 discriminator local 2 discriminator remote 1 commit quit验证配置结果# 配置完成后,在RouterA和RouterB上执行display bfd session all verbose命令,可以看到建立了一个单跳(one hop)的BFD Session,且状态为Up。
# 以RouterA上的显示为例。
