Why each option
MAC masquerading is configured by specifying a desired MAC address for each VLAN on which this failover feature is to be enabled.
MAC masquerading is configured on a per-VLAN basis by assigning a specific MAC address to a VLAN. This ensures that the active BIG-IP system uses the same MAC address for traffic on that VLAN, regardless of which physical device is active, facilitating seamless failover for upstream devices.
MAC masquerading is associated with VLANs and network interfaces, not directly with self-IP addresses, although self-IPs reside on VLANs.
While synchronization occurs, the primary configuration step is to specify the MAC address for each VLAN, not just on the active system for synchronization.
Floating self-IP addresses are used for failover, but MAC masquerading is applied to the VLAN itself, not individually to each floating self-IP address.
