Which network virtualization technologies can be used with an Ethernet VPN (EVPN) deployment in NSX-T Data Center?

In an Ethernet VPN (EVPN) deployment within NSX-T Data Center, Virtual Extensible Local Area Network (VXLAN) is the correct technology to use. VXLAN acts as an overlay technology that facilitates the creation of virtual Layer 2 networks over a Layer 3 infrastructure. This encapsulation allows for the extension of Layer 2 networks across diverse physical locations while maintaining the scalability and efficiency required for large-scale data center environments.

In the context of an EVPN, VXLAN provides the necessary tunneling mechanism to enable communication between different segments of the virtual networks, making it integral to the proper functioning of EVPN. The encapsulated packets in VXLAN can carry both unicast traffic and multicast traffic, which is essential for efficiently managing broadcast domains in virtualized environments.

This deployment leverages the benefits of both EVPN and VXLAN, including better network segmentation, enhanced scalability, and improved routing capabilities, which are critical for multi-tenant environments where such requirements are paramount.
