Configuring a VXLAN Tunnel

Configuring a VXLAN Tunnel

VXLAN uses MAC-in-UDP encapsulation to extend Layer 2 networks, allowing a large number of tenant accesses to virtual networks.

Context

After you configure local and remote VNIs and VTEP's IP addresses, a VXLAN tunnel is statically created. This configuration is simple, as no protocols are involved.

To ensure VXLAN packet forwarding, VXLAN tunnels must be configured on both Layer 2 and Layer 3 VXLAN gateways.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run bridge-domain bd-id

    The BD view is displayed.

  3. Run vxlan vni vni-id

    A VNI is created and mapped to the BD.

    By default, no VNI is created.

  4. Run quit

    Return to the system view.

  5. (Optional) Run vxlan tunnel-status track exact-route

    Subscription to the status of the exact route to the VXLAN tunnel destination is enabled. The VXLAN tunnel is Up only when the exact route to its destination IP address is reachable.

    By default, subscription to the status of the exact route to a VXLAN tunnel destination is disabled. A VXLAN tunnel is considered Up if its source IP address and the network segment where its destination IP address resides are reachable.

  6. Run interface nve nve-number

    An NVE interface is created, and the NVE interface view is displayed.

    By default, no NVE interface is created.

  7. Run source ip-address

    An IP address is configured for the source VTEP.

    By default, no IP address is configured for a source VTEP.

    Either a physical interface's IP address or loopback interface address can be specified for a source VTEP. Using the loopback interface address as the source VTEP's IP address is recommended.

  8. Run vni vni-id head-end peer-list ip-address &<1-10>

    An ingress replication list is configured.

    By default, no ingress replication list is configured.

  9. Run commit

    The configuration is committed.
