Well... Yes. You really do need big3d. Although you could probably get away with defining the GTM server as 'Other' and manually defiing everythign and sorting out a decent monitor, but defining it as BigIP and using bigip as the monitor is probably the best (Then big3d tells gtmd the status of the VS's).
The VS's are then added as members to the GTM pool, and the GTM pool added to the wideip. CHeck teh status of the GTM pool members. If at least one of them isn't up you'll get strange results (With 0 TTL's) on the wideip responses).
