NOTE:
• You might configure different authentication modes and authentication keys for the VRRP groups on an
interface. However, the members of the same VRRP

roup 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, prolon
