要求：PC组1为 Windows系统的PC，PC组2为Liunx系统的PC，从PC组1发送出去的数据包以R2为主路由发送出去，R3为备份路由，从PC组2发送出去的数据以R3为主路由发送数据，R2为备份路由，当其中要是有一台路由DOWN的时候数据全部从UP的那台路由转发送出去。

现在在R2上看一下,发现组1中R2是主路由而R3是主路由,说明配置已经成功
R2#sh standby bri
P indicates configured to preempt.
|
Interface Grp Prio P State Active addr Standby addr Group addr
Fa0/0 1 110 P Active local 192.168.0.5 192.168.0.6
Fa0/0 2 100 Standby 192.168.0.5 local 192.168.0.7
R3#sh standby bri
P indicates configured to preempt.
|
Interface Grp Prio P State Active addr Standby addr Group addr
Fa0/0 1 100 P Standby 192.168.0.1 local 192.168.0.6
Fa0/0 2 110 P Active local 192.168.0.1 192.168.0.7
然后分别在PC1和PC2上用扩展Ping测试一下数据包发送的路径,都能正常按照个自的主路由发送出去
