Cisco Cisco routers HSRP configuration and troubleshooting those things ~ ~

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
