Cisco Enhances VXLAN: Eliminates IP Multicast Requirement, integrates virtual services via vPath plus connects to legacy networks
Cisco introduced enhancements to its VXLAN implementation in the Nexus 1000V virtual switch that overcomes the requirement for IP Multicast. In addition Cisco is integrating vPath to VXLAN for service insertion that stitches virtual services into VXLAN overlay tunnels. Network services might include virtual firewalls, application delivery controllers, WAN optimization, network monitors, etc. A final VXLAN challenge that network teams are facing is how to integrate VXLAN into legacy networks and with existing physical networks, appliances and the enterprise WAN. We’ll hear if Cisco has any solutions to get around this issue as well. Han Yang of Cisco joins me to discuss VXLAN, without multicast and with vPath, and how it can be used to deploy virtual network overlays.
