• A high volume of network traffic might cause a backup to fail to receive VRRP advertisements from
the master within the specified time, resulting in an unexpected master switchover. To solve this
problem, configure a larger interval.
Configuration procedure
To configure the IPv6 VRRP advertisement interval:

To maintain system stability, HP
recommends that you set the
VRRP advertisement interval to
be greater than 100
centiseconds.
