  • Page 6: Vxlan Overview

    The transport edge devices are VXLAN tunnel endpoints (VTEP). They can be servers that host VMs or independent network devices. An HPE VTEP uses VSIs and VXLAN tunnels to provide VXLAN services. • VSI—A virtual switch instance is a virtual Layer 2 switched domain. Each VSI provides switching services only for one VXLAN.

  • Page 8: Working Mechanisms

    Working mechanisms The VTEP uses the following process to forward an inter-site frame: Discovers remote VTEPs, establishes VXLAN tunnels, and assigns the VXLAN tunnels to VXLANs. Assigns the frame to its matching VXLAN if the frame is sent between sites. Performs MAC learning on the VXLAN's VSI.

  • Page 9: Traffic Forwarding

    The VTEP can also u se VXLAN IS-IS in the c ontrol plane to advertise lo cal MAC reach ability information to remote sites and learn MAC reachability information from remote sites. A VSI's MAC address table includes the following types of MAC address entries: •...

VXLAN supports the following modes for flood traffic: • Unicast mode—Also called head-end replication. The source VTEP replicates the flood frame, and then sends one replica to the destination IP address of each VXLAN tunnel in the VXLAN.

  • Page 13: Vxlan Ip Gateways

    Figure 7 ARP flood suppression ARP flood suppression uses the following workflow: VM 1 sends an ARP request to obtain the MAC address of VM 7. VTEP 1 creates a suppression entry for VM 1, and floods the ARP request in the VXLAN. VTEP 2 and VTEP 3 de-encapsulate the ARP request.

This section uses this figure to describe the forwarding p rocesses for intra-VXLAN traffic, inter-VXLAN traffic, and traffic from a VXLAN to an external netwo rk. In these p rocesses, VTEPs use dynami cally learned ARP entries.
  • Page 32 Intra-VXLAN traffic forwarding between sites As shown in Figure 14, the network uses the following process to forward traffic in a VXLAN between sites (for example, from VM 1 to VM 4 in VXLAN 10): VM 1 sends an ARP request to obtain the MAC address of VM 4. GW 1 performs the following operations: a.

  • Page 33: Configuration Prerequisites

    b. Replaces the sender MAC address in the request with the MAC address of VSI-interface 20 on GW 2, and then sends the reply to GW 1. GW 1 de-encapsulates the ARP request and creates an ARP entry for VM 5. The entry contains VM 5's IP address 20.1.1.12, the MAC address of VSI-interface 20 on GW 2, and the incoming tunnel interface.

    The ENDC adds the regi ster timer setting to each register packet. The ENDS reco rds this timer setting when it adds the ENDC to the ENDC datab ase. If no reg ister update is received from the ENDC before five times the timer is reached, ENDS removes the ENDC. ENDP authentication ENDP authentication prevents malicious registration with an ENDS in an insecure network.
