Note: NSX doesn’t include provisions for Multicast switching or routing, and follows standard Ethernet behaviour, which is to flood frames with Multicast destination MAC addresses within their L2 domain, i.e., individual VXLAN.Ī frame is considered Unknown Unicast by a host if it doesn’t have a corresponding MAC to VTEP IP cached entry. “BUM”), send it to all VTEPs for that given VXLAN. If that MAC address was a Broadcast, Unknown Unicast, or Multicast (a.k.a.When a VM on that host connected to an LS sends a frame addressed to a particular MAC address, figure out VTEP IP address of a host where this destination MAC address resides and.In general, each host running VXLAN needs to be able to do the following two things: Operational considerations for each of the modes.Additional Control Plane function enabled by NSX Controllers (ARP suppression).Traffic replication in the three modes, and how to calculate corresponding overheads.How VXLAN Control Plane information gets to the hosts. Fundamental VXLAN Control Plane functions, and how they’re implemented in three modes. Since this topic is a bit large, here’s a brief outline of what we’ll be talking about. In this post, I’m covering how each mode works along with some of those negatives and positives, to hopefully help you can make a better informed choice for your circumstances. None of these is “simply better” than others each has it’s positive and negative sides.
