The video looks into Virtual Extension LAN (VXLAN) support on Cisco Nexus 1000V. VXLAN allows VLAN ID to be extended to 24 bits, or in other words, essentially increases number of available VLAN from 4096 to more than 16 million VLAN. We will configure VXLAN on port-profile. In this lab, we intentionally have VEM control interfaces separated by layer 3 to demonstrate MAC-in-IP encapsulation provided by VXLAN to extend an isolated layer 2 domain across a routable and multicast-enabled network.
