Virtual Server between two subnets belonging to two different Traffic Groups.

I should create a Virtual Server in a BIG-IP LTM DSC active-active group between two vlans assigned to two different Traffic-Groups.

The BIG-IP LTM allows to setup a Virtual Server by setting as Source and Destination Addresses the Floating IPs of both vlans belonging to different Traffic-Groups respectively. I understand that this shouldn’t pose any problem if both Traffic Groups are active within the same BIG-IP LTM member of an active-active DSC

My question is what will happen if one of the two Traffic-Groups fails over to another member of the active-active DSC?
