248BConfiguration guidelines
• 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 firewalls 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 firewall in the VRRP group.
