Abstract:
Techniques are provided for hosting a first virtual switch and one or more virtual machines (VMs) configured to be part of a virtual LAN (VLAN). The first virtual switch enables communications among the VMs arranged in one or more private VLANs (PVLANs). The first virtual switch receives a packet from a source VM that is evaluated for source identifier information associated and destination identifier information associated with a destination VM serviced by a second virtual switch for which the packet is destined. An evaluation result is obtained. Based on the evaluation result, the first virtual switch determines whether the source and destination VMs belong to a same PVLAN and drops the packet if the source VM and the destination VM do not belong to the same PVLAN.
