We discussed the theoretical knowledge of VXLAN and completed the relevant configuration in ML2.
Today you will create vxlan100_net through the Web UI and observe the changes in the node network structure.

Neutron created the following:
1. vxlan100 corresponding bridge BRQ1762D312-D4
2. Vxlan interface vxlan-100
3. DHCP Tap device tap4df76d0e-59
Vxlan-100 and tap4df76d0e-59 are already connected to BRQ1762D312-D4,VXLAN100 's two-layer network ready.
Perform ip-d link show dev vxlan-100 to view the detailed configuration of the Vxlan interface.

Visible, vxlan-100 VNI is 100, the corresponding VTEP network interface is eth1.
At this point the VXLAN100 structure:

In the next section we will deploy instance to vxlan100_net and analyze the connectivity of the network.
