I don't know if you have seem this already, but there is a good response to a similar MAC masquerade question here: https://devcentral.f5.com/questions/how-does-mac-masquerading-work-exactly-50993

 

MAC Masquerade applies to the traffic group. Yes, gARPs are still issued when a failover occurs but, as the article states, the effect is minimized since the MAC address itself does not change. MAC masquerade reduces the possibility that devices that are slower to respond to gARP will still try to send traffic to the device that failed.
