Both devices are connected to both data centers. I want one BIG-IP to remain active for both unless there is a problem. Really the only problem that I am trying to overcome is if the locally connected switch stops functioning properly. With that said, I think what I need to do is configure gateway fail-safe on each device, with the real switch IP address for each VLAN (ie. not the vrrp virtual gateway). If that stops responding, it's safe to say communications on that switch will not be functioning.
Let's see if I am understanding this right...
VLAN 1 is in DC1 and is in Traffic Group 1. VLAN2 is in DC2 and is in Traffic Group 2.
In DC1, SW1 is 1.1.1.1, SW2 is 1.1.1.2 and the virtual is 1.1.1.3. On F51, which connects to SW1, I will have gateway failsafe on 1.1.1.1. On F52, which connects to SW2, I will have gateway failsafe on 1.1.1.2. F51 is active, loses connectivity to 1.1.1.1, and fails over traffic group 1 ONLY to F52. What happens to VLAN 2 and traffic group 2? Does the F5 know to only failover traffic group 1 since that is the traffic group VLAN1 resides in?
Hopefully that is not too confusing...
Thanks for all the help.
