- Network requirements
• • Host A needs to access Host B on the Internet, the default gateway of Host A is 10.1.1.111/24;
• • When Switch A normal working hours, Host A sends packets to Host B are forwarded through Switch A ; Switch a occurs when the
failure, Host a to Host B transmits packets are forwarded by Switch B.
Configuration procedure
NOTE: IntranetSwitch only play the role of the exchange, in this case do not have to configure
(1) A Configuration Switch
1. Configure VLAN2
2. Create a backup group 1, and configure the virtual IP address group 1 is 10.1.1.111
3 set in Switch a backup group 1 priority 110, is higher than the priority of Switch B 100

(2) Configuration Switch B
1. Configure VLAN2
2. Create backup group 1, and configure the virtual IP address of the group 1 is 10.1.1.111
3. Switch B is provided in the backup priority group 1 to 100
4. Set Switch B work in preemptive mode, the delay time is 5 seconds preemption
(3) Configuration C Switch
1. Configuration VLAN2
3. configuration on Host A can ping Host B. See the results after the configuration of the display vrrp verbose command. For more information on the display 1 VRRP group Switch A.
