The above information indicates that in VRRP group 1 LB A is the master, LB B is the backup and packets
sent from Host A to Host B are forwarded by LB A.
If LB A fails, you can still ping through Host B on Host A. You can use the display vrrp verbose command
to view the detailed information of the VRRP group on LB B.
