Network node configuration for VXLAN tenant networks

Network node configuration for VXLAN tenant networks

In the VXLAN-based tenant networks, the network node terminates VXLAN mesh tunnels and sends traffic to external provider VLAN networks. Therefore, all tagged interfaces must be configured directly in Neutron OVS as internal ports without Linux bridges. Bond0 is added into br-floating, which is mapped as physnet1 into the Neutron provider networks. br-mgm and br-mesh are Neutron OVS internal ports with tags and IP addresses. As there is no need to handle storage traffic on the network nodes, all the sub-interfaces can be created in Neutron OVS. This also allows for the creation of VLAN providers through the Neutron API.

The following diagram displays the network node configuration for the use case with Neutron VXLAN tenant networks and external access configured on the network node only.
