No, because I get a Error, if I config the sec. VIP:

The entered virtual IP is in the same subnetwork as one of the network interfaces or virtual IPs that already exist in the system.
It is recommend to use IP that has a unique subnetwork class and is not used in any other place in your configuration.
Do you want to continue?

first VIP: 192.168.8.40 / 255.255.248.0
sec. VIP: 192.168.9.40 / 255.255.248.0
