1、实验四十、HSRP的配置一、实验目的1.掌握热备份路由协议的配置2.理解热备份路由协议的原理二、应用环境在企业网内部实现网关的冗余，提高可靠性三、实验设备1.DCR-1751两台2.PC机一台四、实验拓扑五、实验要求ROUTER-AROUTER-BF0/0192.168.10.2/24F0/0192.168.10.3/24优先级200100StandbyIP192.168.10.1/24PC机IP：192.168.10.4/24网关：192.168.10.1目的：正常情况下A为活跃路由器，当A坏掉，B成为活跃路由

2、器，从PC机PING网关没有变化六、实验步骤第一步：配置接口地址，并测试连通性第二步：配置HSRP路由器A的配置：Router-A_config#intf0/0Router-A_config_f0/0#ipaddress192.168.10.2255.255.255.0Router-A_config_f0/0#standbypriority200！配置优先级Router-A_config_f0/0#standbyip192.168.10.1！配置虚拟地址Router-A_config_f0/0#standauth

4、三步：配置PC机IP地址和网关，并测试网关第四步：验证Router-A#shstandbyFastEthernet0/0-Group0HSRPStateisActiveVirtualIPaddress:192.168.10.1/24(config)VirtualMacaddress:0000.0c07.ac00ActiveRouterIP:192.168.10.2StandbyRouterIP:192.168.10.3PreemptisnotsetCurrentPriorityis200ConfigPriorit

7、PC机的网关是StandbyIP，也就是虚拟地址八、配置序列Router-B#shrunBuildingconfiguration...Currentconfiguration:!!version1.3.2Eservicetimestampslogdateservicetimestampsdebugdatenoservicepassword-encryption!hostnameRouter-B!iphosta192.168.1.1iphostc192.168.2.2!!interfaceFastEthernet
