VIP - MAC Address

Where multiple VLANs are concerned the same rules apply but per VLAN, so the VS will have a different MAC for each VLAN it is listening/enabled on. ARP responses 'would' change per VLAN to reflect this but as the IP range could only exist on one VLAN or VLAN group, ARP will only be used where the VS address is in the same subnet as the Self IP for a VLAN, if any. For all others traffic would have to be directly routed to the device. It doesn't matter where the Pool Members are as the VS address is not used to communicate with them, the floating (if configured) or real Self IP of the egress VLAN is.
