The video looks at how we can achieve network separation at layer 2 with private vlan on Cisco Nexus 1000V. We will go through the concept of Primary, Secondary, Isolated and Community VLANs, and experiment with server communication by placing the servers on different vlan. At the end of the video, we will also go through a scenario where we have two sets of private vlan. Private VLAN allows hosts to remain segregated on the same IP subnet.
