You may 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 may cause a backup to trigger a change of its status because the backup

problem, prolong the time interval to send VRRP advertisements.
z
Configuring different intervals for sending VRRP advertisements on the routers in a VRRP
group may 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.

Monitoring Configuration Guide.
