Users report that traffic is negatively affected every time a BIG-IP device fails over. The traffic becomes stabilized after a few minutes. What should the BIG-IP Administrator do to reduce the impact of future failovers?
When a failover occurs, the newly active device must inform the surrounding network that it now " owns " the shared IP addresses. Without MAC Masquerade, the new device uses its own hardware MAC, requiring upstream routers to update their ARP tables (which causes a delay). MAC Masquerading allows the HA pair to share a " floating " MAC address, ensuring the Control Plane transition is transparent to the network layer
