First highlight the required commands to:
To configure the members of HSRP:
Router (config-if) #standby Backup Group number IP Backup Group Virtual IP Address
Configuration HSRP Priority:
Router (config-if) #standby Backup Group number Priority Priority Level
Configure Port Tracking: Configure on the active router
Router (config-if) #standby Backup Group number Track Trace Interface
Configuration HSRP preemptive right: Configure on the backup router
Router (config-if) #standby Backup Group number preempt
To view the HSRP information:

Here is an explanation of the experiment:

Three layer switch 0 Configuration Fast Ethernet interface F0/2:
Switch (config) #interface fastethernet 0/2
Switch (config-if) #no Switchport
Switch (config-if) #ip address 192.168.2.1 255.255.255.0
Switch (config-if) #no shutdown
Switch (config-if) #exit
Yes, of course. Three Layer switch 1 Configure the Ethernet interface F0/2 the same.
Switch (config) #interface fastethernet 0/2
Switch (config-if) #no Switchport
Switch (config-if) #ip address 192.168.3.1 255.255.255.0
Switch (config-if) #no shutdown
Switch (config-if) #exit
Since the configuration of HSRP must be configured on the gateway, the IP address is configured on the VLAN1 of the two three-layer switches respectively, which is the address of the gateways for the two hosts below.
The configuration commands are as follows:
Switch (config) #interface vlan 1
Switch (config-if) #ip address 192.168.1.252 255.255.255.0
Switch (config-if) #no shutdown
Switch (config-if) #exit
Similarly, the three layer switch is configured as follows:
Switch (config) #interface vlan 1
Switch (config-if) #ip address 192.168.1.253 255.255.255.0
Switch (config-if) #no shutdown
Switch (config-if) #exit
Why is there no configuration 192.168.1.254 here, because 192.168.1.254 is the virtual gateway address of HSRP. The routing feature is turned on for layer three switches below.
Switch (config) #ip routing
Here are the detailed configuration steps for configuring the router: Configure the IP address and enable the port for the router's three interfaces, as a simple one:
Router (config) #interface fastethernet 0/0
Router (config-if) #ip address 192.168.2.254 255.255.255.0
Router (config-if) #no shutdown
Router (config-if) #exit
Router (config) #interface fastethernet 0/1
Router (config-if) #ip address 192.168.3.254 255.255.255.0
Router (config-if) #no shutdown
Router (config-if) #exit
Router (config) #interface fastethernet 1/0
Router (config-if) #ip address 192.168.4.254 255.255.255.0
Router (config-if) #no shutdown
Router (config-if) #exit
After configuring RIP for layer three switches and routers, the command is as follows:
(1) Three-layer switch 0 configuration:
Switch (config) #do sh ip rou
CODES:C-connected, s-static, I-igrp, R-rip, M-mobile, B-BGP
D-EIGRP, Ex-eigrp External, O-OSPF, IA-OSPF Inter area
N1-OSPF NSSA External Type 1, N2-OSPF NSSA external type 2
E1-OSPF external Type 1, E2-OSPF external type 2, E-EGP
I-is-is, L1-is-is level-1, L2-is-is level-2, ia-is-is Inter area
*-Candidate default, U-per-user static route, O-ODR
P-periodic downloaded static route
Gateway of last resort are not set
C 192.168.1.0/24 is directly connected, Vlan1
C 192.168.2.0/24 is directly connected, FASTETHERNET0/2
Switch (config) #router rip
Switch (config-router) #version 2
Switch (config-router) #no auto-summary
Switch (config-router) #network 192.168.1.0
Switch (config-router) #network 192.168.2.0
(2) Three-layer switch 1 configuration:
Switch (config) #do sh ip rou
CODES:C-connected, s-static, I-igrp, R-rip, M-mobile, B-BGP
D-EIGRP, Ex-eigrp External, O-OSPF, IA-OSPF Inter area
N1-OSPF NSSA External Type 1, N2-OSPF NSSA external type 2
E1-OSPF external Type 1, E2-OSPF external type 2, E-EGP
I-is-is, L1-is-is level-1, L2-is-is level-2, ia-is-is Inter area
*-Candidate default, U-per-user static route, O-ODR
P-periodic downloaded static route
Gateway of last resort are not set
C 192.168.1.0/24 is directly connected, Vlan1
C 192.168.3.0/24 is directly connected, FASTETHERNET0/2
Switch (config) #router rip
Switch (config-router) #version 2
Switch (config-router) #no auto-summary
Switch (config-router) #network 192.168.1.0
Switch (config-router) #network 192.168.3.0
Switch (Config-router) #exit
If this is all configured, then use the ping command to test it!
Here is a start-up-configuring HSRP Hot Spares:
Configure on the active three-layer switch:
Switch (config) #interface vlan 1
Switch (config-if) #standby 1 IP 192.168.1.254
Switch (config-if) #standby 1 priority 200
Switch (config-if) #standby 1 track fastethernet 0/2
Switch (config-if) #standby 1 preempt
Configure on the backup layer three switch:
Switch (config) #interface vlan 1
Switch (config-if) #standby 1 IP 192.168.1.254
Switch (config-if) #standby 1 priority 195
Switch (config-if) #standby 1 preempt
