1.4.5 VRRP Auto Detect Configuration Example

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.
