VXLAN

In this section:

  1. VXLAN Gateway Overview
    Virtual Extensible Local Area Network (VXLAN) is an overlay technology to create a logical Layer 2 network on top of a Layer 3 IP network.
  2. MAC Learning
  3. Failure Detection and Redundant Remote Connections
    You can configure keep-alive messages to detect loss of connection at the remote end of the VXLAN tunnel and redundant secondary IP addresses to restore the connection.
  4. Quality of Service Support
  5. Unsupported Features
  6. VXLAN Configuration Considerations
  7. Inter-VLAN Routing Using an External Router with VXLAN VTEPs
  8. Configuring VXLAN
  9. Gathering VXLAN Statistics
    You can collect and control certain statistics pertaining to VXLAN virtual ports and VXLAN Network Identifiers (VNIs). The following task enables detailed statistics collection for a VNI.
  10. Clearing VXLAN Statistics
    You can clear statistics for an entire VXLAN gateway tunnel or for a particular VXLAN Network Identifier (VNI).
  11. Displaying VXLAN Information
    You can display information on VXLAN gateways, connections, and tunnels.
  12. MACsec over VXLAN
    MACsec over VXLAN is an end-to-end security protocol that provides a secured environment to protect Ethernet frames traveling over IP networks. Though Virtual Extensible Local Area Network (VXLAN) provides a Layer 2 extension across the LAN/WAN, a connection between sites is not secured. MACsec over VXLAN addresses this and achieves a secure Layer 2 extension across the LAN/WAN using cross-connect VXLAN Network Identifiers (VNIs).
  13. VXLAN Routing In and Out of Tunnels (RIOT)
    VXLAN Routing In and Out of Tunnels (RIOT) allows hosts in different VXLAN Network Identifiers (VNIs) to communicate by performing Layer 3 routing on the inner packets at the Virtual Tunnel Endpoint (VTEP). Packets are routed between VXLAN segments without requiring a separate physical router.
