HSRP实现链路冗余实验
这是我用小黄帽做得实验,实验拓扑图如下：下面是配置（以上设备均使用的是思科的3640的IOS）：R1#show running-configBuilding configuration...Current configuration : 943 bytesversion 12.4service timestamps debug datetimemsecservice timestamps log datetimemsecno service password-encryptionhostname R1boot-start-markerboot-end-markernoaaa new-modelmemory-sizeiomem 5ipcefnoip domain lookup interface FastEthernet0/0ip address 192.168.100.1 255.255.255.0duplex autospeed auto interface FastEthernet1/0ip address 192.168.0.1 255.255.255.0duplex autospeed auto interface FastEthernet2/0ip address 192.168.1.1 255.255.255.0shutdownduplex autospeed autoip http servernoip http secure-serverip route 192.168.2.0 255.255.255.0192.168.0.2 50ip route 192.168.2.0 255.255.255.0192.168.1.2 60ip route 192.168.3.0 255.255.255.0192.168.1.2 50ip route 192.168.3.0 255.255.255.0192.168.0.2 60 control-planeline con 0exec-timeout 0 0logging synchronousline aux 0linevty 0 4 endSW1#show running-configBuilding configuration...

在用PC1 PING PC3 1000次时，过一会把SW1的ｆ0/0端口和R1的f1/0端口DOWN时，出现如下现象：在用PC2 PING PC3 1000次时，过一会把SW2的ｆ0/0端口和R1的f2/0端口DOWN时，出现如下现象：以上两个图很容易看到HSRP的运行效果。
走过了年少，脚起了水泡 如果有一双眼睛陪我一同哭泣，就值得我为生命受苦。 有事秘书干，没事干秘书! 找到好贴不容易，我顶你了，谢了 为中华而努力读书!一包中华好多钱啊~~~ 不知该说些什么。。。。。。就是谢谢
