网络安全-HSRP协议
2022-07-05 13:31:00 【IT之一小佬】
HSRP协议(Hot StandBy Router Protocol)热备份路由器协议
- HSRP组号:1-255
- 组号没有大小之分
- 虚拟路由器的IP称为虚拟IP地址
- HSRP组成员
虚拟路由器(老大)
活跃路由器
备份路由器
其他路由器
- HSRP优先级(1-255):默认100
- HSRP组成员通过定时发送hello包来交流默认每隔3秒
- 占先权preempt:作用–当检测不到对方,或检测到对方优先级低于自己,立即抢占活跃路由的名分。
- 配置跟踪track,跟踪外网端口状态,当外网down掉,则自降优先级
