VXLAN tunnel configuration

Examples that show you how to configure a VXLAN tunnel.

In the examples in this section, Vyatta routers R1 and R2 are configured as VTEPs. H1 and H2 are hosts that are connected to R1 and R2. These hosts communicate with each other over the VXLAN tunnel.

The VXLAN tunnel is established between the two VTEPs and it runs over a normal IP transport layer.

The two VTEPs in these examples are on the same subnet (10.10.2.x/24 network), but they don't have to be. The VTEPs can be on any subnet as long as they are reachable via normal routing protocols.

Figure 1. VXLAN tunnel example diagram. This shows a simple, traditional VXLAN tunnel. The full L2 payload is carried over the tunnel.
  • The hosts, H1 and H2 are on the overlay network. (
  • The VTEP, R1 is directly connected to H1; and the second VTEP, R2, is directly connected to H2. The transport network is
  • The VXLAN tunnel and the interface connecting each host are members of a bridge (br1) on each router.
  • H1 and H2 can ping each other over the VXLAN tunnel, because the packets are bridged across the VXLAN tunnel.
