Local ND proxy implements Layer 3 communication for two hosts in the following cases:
• The two hosts connect to ports of the same device and the ports must be in different VLANs.
• The two hosts connect to isolated Layer 2 ports in the same isolation group of a VLAN.
• If super VLAN is used, the two hosts must belong to different sub VLANs.
• If Private VLAN is used, the two hosts must belong to different secondary VLANs.
