Just an idea did not think about it too much - what about running each bridge device in separate VLAN and make virtual IPs behind the bridging devices? Someting like this:

 

 

VIP MX has pool of nodes AC1 AC2 AC3 and AC4, these are each in different VLAN each containing one bridging device, which forces LTM to push traffic through given bridging device. AC1-4 are VIPs each having pool of internal SMTP servers.

 

 

To solve:

 

- is it possible to use one F5 or is it needed to have external and internal one? Easiest way is to have two of them with inbound VIP on external and AC VIPs on internal. The same on the way out.

 

- monitoring of bridging devices.
