End   为了测试配置结果，当把R2DOWN的时候R3自动转成了Active状态，当R2UP后因为R2配了抢占，而且R2的优先级要高于R3，R2又抢占回Active状态。而R3又回到了Speak状态。 R2(config-if)#sh 01:13:48: %STANDBY-5-STATECHANGE: FastEthernet0/0 Group 1 state Active -> Init   R3#      01:09:26: %STANDBY-5-STATECHANGE: FastEthernet0/0 Group 1 state Standby -> Active     R2(config-if)# 01:18:08: %STANDBY-5-STATECHANGE: FastEthernet0/0 Group 1 state Listen -> Active   R3# 01:13:29: %STANDBY-5-STATECHANGE: FastEthernet0/0 Group 1 state Active -> Speak
