Hi, Any update for the document about how to create network with Multi-Segemnt??

What is a multi-segment network A multi-segment network is exactly as it sounds: A single Neutron network which is comprised of multiple, disparate individual segments. These could be the same type, such as both VLANs or both GRE tunnels. But they conceptually make up a single Neutron network. > 2. How it works. Internally, ML2 will ensure these are both part of the same network. However, for traffic to flow individually between them, you will need to "bridge" (for lack of a better word) these networks together externally. The typical use case here would be something like a VXLAN to VLAN GW, which could be done in a ToR which supports both VLANs and VXLANs. At some point we plan to implement this "bridging" using a vSwitch such as OVS as well. > 3. Why would people need this kind of network configuration usage. If you have some devices, VMs, or hosts on one type of network (e.g. VLAN), and you want to provide access to devices, VMs, or hosts on another type (e.g. VXLAN), this allows you to do that. > 4.

Vish was going to have a look at this and see what he could setup, if he has done that maybe he'll reply here. Otherwise, I'll come up with some rough documentation and send it out.
