I. Network requirements
Switch B and switch D form VRRP backup group 1, whose virtual IP address is
192.168.1.10.
Packets sourced from Switch A and destined for Switch C is forwarded by Switch
B under normal situations.
When the connection between Switch B and Switch C fails, Switch D becomes
the Master in backup group 1 automatically and the link from Switch D to Switch
C, the secondary link, is enabled.
