Introduction to Virtual Extensible LAN (VXLAN) - NetworkLessons.com

VXLAN is a tunneling protocol that tunnels Ethernet (layer 2) traffic over an IP (layer 3) network. It uses an overlay and underlay network, a VNI identifier, and a VTEP device to encapsulate and de-encapsulate layer 2 frames. Learn the advantages, disadvantages, and examples of VXLAN in this lesson.

Virtual Extensible LAN - Wikipedia

VXLAN is a solution to support a flexible, large-scale multitenant environment over a shared common physical infrastructure. The transport protocol over the physical data center network is IP plus UDP. VXLAN defines a MAC-in-UDP encapsulation scheme where the original Layer 2 frame has a VXLAN header added and is then placed in a UDP-IP packet.

What Is VXLAN? How Does It Differ from VLAN? - Huawei

VxLAN is a way to group devices at layer-2 and create virtual networks that are overlaid on a physical network. It has advantages such as large address space, decoupling, scalability, and mobility. Learn the key concepts, frame format, and topology of VxLAN.

What is VXLAN? | Juniper Networks US

VXLAN technology allows you to segment your networks (as VLANs do), but it provides benefits that VLANs cannot. Here are the most important benefits of using VXLANs: You can theoretically create as many as 16 million VXLANs in an administrative domain (as opposed to 4094 VLANs on a Juniper Networks device).

Configure VXLAN - Cisco

Virtual eXtensible Local Area Network (VXLAN) is one of the Network Virtualization over Layer 3 (NVO3) technologies defined by the Internet Engineering Task Force (IETF) and is an extension to Virtual Local Area Network (VLAN). VXLAN encapsulates a Layer 2 Ethernet frame into a UDP packet and transmits the packet over a Layer 3 network.

Introduction to VXLAN - Cisco Learning Network

VXLAN components are: VTEP: this is where VXLAN encapsulation and decapsulation is done, basically a Router or A Switch; VNID: VXLAN network identifier which is the 24-bit segment that identifies the broadcast domain; NVE: Network virtual interface (logically) created on the VTEP; Examples of VXLAN

That said, here are the main differences between VXLAN and VLAN. VLAN has a 12-bit identifier called VID while VXLAN has a 24-bit identifier called VID network identifier. This means that with VLAN you can create only 4094 networks over ethernet, while with VXLAN, you can create up to 16 million.

Virtual Extensible LAN (VXLAN) Overview - Cisco Press

Learn what VXLAN is, how it works, and where to use it. VXLAN is an overlay network virtualization technology that can scale layer 2 segments across layer 3 network infrastructure.

What is VXLAN (Virtual Extensible LAN) - IP With Ease

Virtual Extensible LAN (VXLAN) is a network virtualization technology that attempts to address the scalability problems associated with large cloud computing deployments. It uses a VLAN -like encapsulation technique to encapsulate OSI layer 2 Ethernet frames within layer 4 UDP datagrams, using 4789 as the default IANA -assigned destination UDP ...

PDF Introduction to VXLAN - Cisco

Virtual eXtensible Local Area Network (VXLAN) is a tunneling protocol designed to solve the problem of limited VLAN IDs (4096) in IEEE 802.1Q, and it is described by IETF RFC 7348. With VXLAN the size of the identifier is expanded to 24 bits (16777216). It creates a Layer 2 overlay scheme on a Layer 3 network and the protocol runs over UDP.
