Intelligent way to load balance management IP Addresses

You can't add an irule to the management address. One way would be to manage the bigip via a self-ip. That way you could use the floating self-ip and it'll always use the active one.

Else, you could add a splash page to ask people to check it's the active device when they login. If I recall this is in the Platform section of the GUI, but I may be wrong.
