NOTE:
•
You might configure different authentication modes and authentication keys for the VRRP groups on an
interface. However, the members of the same VRRP group must use the same authentication mode and
authentication key.
• Excessive traffic might cause a backup to trigger a change of its status because the backup does not
receive any VRRP advertisements for a specified period of time. To solve this problem, prolong the time
interval to send VRRP advertisements.
• Configuring different intervals for sending VRRP advertisements on the routers in a VRRP group might
cause a backup to trigger a change of its status because the backup does not receive any VRRP
advertisements for a specified period of time. To solve this problem, configure the same interval for
sending VRRP advertisements on each router in the VRRP group.

Network requirements
• Host A needs to access Host B on the Internet, using 202.38.160.111/24 as its default gateway.
• Router A and Router B belong to VRRP group 1 with the virtual IP address of 202.38.160.111/24.
• If Router A operates normally, packets sent from Host A to Host B are forwarded by Router A. If
Router A fails, packets sent from Host A to Host B are forwarded by Router B.
