| 5 | 2 | Pau Escrich | The network architecture designed for libre-mesh is based in two layers: |
| 6 | 2 | Pau Escrich | * The cloud layer 2 which runs Batman-Adv |
| 7 | 2 | Pau Escrich | * The network layer 3 which runs BMX6 |

| 11 | 4 | Pau Escrich | All nodes are runing BMX6 and BATADV at same time in the same WiFi devices but different VLANS. |
| 12 | 4 | Pau Escrich | The BMX6 VLAN is always the same, so all link-layer connected nodes will see each other. |
| 13 | 4 | Pau Escrich | The BATADV VLAN depends on the cloud identifier (CID) which is calculed (by default) from the AP SSID. |

| 17 | 4 | Pau Escrich | This configuration allows to isolate the layer 2 clouds. |
| 18 | 4 | Pau Escrich | For instance a neighborhood, a company complex or a street level hotsposts network can choose isolate their LAN from the rest of the network. |
| 19 | 4 | Pau Escrich | However at the same time, they will be able to reach the rest of the community network using the layer 3 routed network. |
| 20 | 4 | Pau Escrich | |
| 21 | 4 | Pau Escrich | In case an entire network community wants to have a single cloud, they can just use the same CID. |
