(Optional) Configuring an Isolated Interface
Context
In data center server virtualization scenarios, multiple virtual machines (VMs) in a physical server may belong to the same VLAN and require Layer 2 isolation. The VMs connect to the same user interface on the MFF-enabled device. Services on the VMs are often isolated, so the MFF-enabled device must respond to ARP request packets. If the MFF-enabled device does not respond to ARP request packets, VMs cannot communicate at Layer 3.
MFF provides the isolated interface to address this issue. After an isolated interface is configured, the MFF-enabled device does not check interface consistency in ARP request packets sent by users. Instead, the MFF-enabled device directly responds to the ARP request packets.
