Final answer:
VMware NSX uses Open vSwitch (OVS) as the open source management framework to manage VXLANs on a Junos device.
Step-by-step explanation:
The open source management framework that VMware NSX uses to manage VXLANs on a Junos device is Open vSwitch (OVS). OVS is a multilayer virtual switch that is used for network virtualization, allowing for the creation and management of virtual networks. It enables the decoupling of the virtual network from the physical infrastructure, providing flexibility and scalability.
With OVS, NSX can create VXLANs, which are virtual LANs that use an overlay network to extend layer 2 connectivity across physical networks. VXLANs are commonly used in software-defined networking (SDN) environments to provide network segmentation and enable multi-tenancy.
By using OVS as the underlying management framework, VMware NSX can effectively manage VXLANs on Junos devices, providing a scalable and flexible solution for network virtualization.
