Hot Backup HSRP detailed configuration instance

HSRPThe hot backup router protocol is designed to support the failure of IP traffic transfer under certain circumstances, which will not cause confusion and allow the host to use a single router, and maintain the connectivity between routers even if the first hop router fails to be used. Next let's take a look at the configuration of the next instance.

Detailed configuration process of hot backup HSRP

R1 Configuration

 
 

  
  
R1 (config) # int f0/0
  
  
R1 (config-if) # ip add 192.168.1.1 255.255.255.0
  
  
R1 (config-if) # no shu
  
  
R1 (config-if) # int f1/0
  
  
R1 (config-if) # ip add 192.168.2.1 255.255.255.0
  
  
R1 (config-if) # no shu
  
  
R1 (config) # router rip
  
  
R1 (config-router) # network 192.168.1.0
  
  
R1 (config-router) # network 192.168.2.0
  
  
R1 (config) # int f0/0
  
  
R1 (config-if) # standby 47 ip 192.168.1.254 the backup group is 47 and the virtual IP address is 1.254.
  
  
R1 (config-if) # standby 47 priority 180 priority is 180
  
  
R1 (config-if) # standby 47 preemtp configuration Preemption
  
  
R1 (config-if) # standby 47 track f1/0 100 port tracking, priority reduced by 100
 
 

R2 Configuration

 
 

  
  
R2 (config) # int f0/0r2 (config-if) # ip add 192.168.1.2 255.255.255.0
  
  
R2 (config-if) # no shu
  
  
R2 (config-if) # int f1/0
  
  
R2 (config-if) # ip add 192.168.3.1 255.255.255.0
  
  
R2 (config-if) # no shu
  
  
R2 (config) # router rip
  
  
R2 (config-router) # network 192.168.1.0
  
  
R2 (config-router) # network 192.168.3.0
  
  
R2 (config) # int f0/0
  
  
R2 (config-if) # standby 47 ip address 192.168.1.254 the backup group is 47 and the virtual IP address is 1.254.
  
  
R2 (config-if) # standby 47 priority 150 priority is 150
 
 

R3 Configuration

 
 

  
  
R3 (config) # int f0/0
  
  
R3 (config-if) # ip add 192.168.2.2 255.255.255.0
  
  
R3 (config-if) # no shu
  
  
R3 (config-if) # int f1/0
  
  
R3 (config-if) # ip add 192.168.3.2 255.255.255.0
  
  
R3 (config-if) # no shu
  
  
R3 (config-if) # int f2/0
  
  
R3 (config-if) # ip add 192.168.4.1 255.255.255.0
  
  
R3 (config-if) # no shu
  
  
R3 (config) # router rip
  
  
R3 (config-router) # network 192.168.2.0
  
  
R3 (config-router) # network 192.168.3.0
  
  
R3 (config-router) # network 192.168.4.0
  
  
VPCS1: ip 192.168.1.3 192.168.1.254 24 VPCS1IP: 1.3 Gateway: 1.254
  
  
VPCS2: ip 192.168.4.2 192.168.4.1 24 VPCS2IP: 4.2 Gateway: 4.1
 
 

Then you can test it.

The introduction of the HSRP protocol does not know whether you have understood the above experiment. I hope you will learn more.
