Configuration Example for Auto Detect Implementation in VRRP

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