A VXLAN overview
VXLAN is a technology developed by vendors such as Arista, VMware, Cisco, and Broadcom. Each of these VXLAN networks is called a logical switch (virtual wires in vCloud network security solution) and they are identified by a 24-bit segment-ID. In this way, customers can create up to 16 million VXLAN networks. Virtual Tunnel End Points (VTEPs) are the endpoints that encapsulate and de-encapsulate the VXLAN frames. Let's understand a few key terminologies in VXLAN; and we will discuss VXLAN frames after that:
VXLAN VIB: VXLAN VIB or VMkernel modules are pushed to an underlying hypervisor during ESXi host preparation from NSX Manager.
Vmknic adapter: Virtual adapter is responsible for sending ARP, DHCP, and multicast join messages. Yes, there would be an IP assigned (static/dynamic) to vmknic from the VTEP IP pool, which is one of the prerequisites for VXLAN configuration. NSX supports multiple VXLAN vmknics per host for uplink load balancing features.
VXLAN port group: VXLAN...
