Cisco配置HSRP网关冗余

  Router1(config)# int GigabitEthernet 0/0
  Router1(config)# ip address 192.168.1.1 255.255.255.255.0
  Router1(config-if)# standby 1 ip add 192.168.1.254    //激活HSRP,设置虚拟网关地址
  Router1(config-if)# standby 1 priority 120    //设定HSRP优先级,具有最高优先级的HSRP为活动路由器默认100
  Router1(config-if)# standby 1 preempt    //开启抢占
  Router1(config-if)# standby 1 track interface GigabitEthernet 0/1 30    //跟踪接口,若接口down则优先级减30
  Router2(config)# int GigabitEthernet 0/0
  Router2(config)# ip address 192.168.1.2 255.255.255.255.0
  Router2(config-if)# standby 1 ip add 192.168.1.254
  Router2(config-if)# standby 1 priority 120
  Router2(config-if)# standby 1 preempt
  Router1# show standby brief    //查看hsrp信息
