the main change is to split the document into several sections. will address new topology later.
| - Uses VM with physical name VM0100 | ||
| - Ethernet1 is connected to vlan 102 | ||
| - Ethernet2 is connected to vlan 103 | ||
| - Ethernet9 is connected to Ethernet9 of ARISTA02T1 |

Need an explanation why? I don't see any '9'-s in the example above. We need a statement that VMs in every topology has a backplane.

added statement in the overview.
| The VMs use Arista vEOS. They are using to setup protocol test such as BGP, LACP, LLDP. They are created using ```testbed-cli.sh start-vms``` command. Each VM uses 2G of RAM and has 10 network interfaces: | ||
|
|
||
| 1. 8 front panel ports. These ports are connected to openvswitch bridges, which are connected to vlan interfaces. The vlan interfaces are connected to the fanout switch (through physical port). | ||
| 2. 1 back panel port. All testbed VMs connected to each other using this port (it isn't shown on the figure above). |

not all VMs are connection through the backplane.
Each topology has its own backplane
| - t1-lag: 24 VMs + PTF container for injected ports. 8 VMs has two ports each in LAG | ||
| - ptf32: classic PTF container with 32 ports connected directly to DUT ports | ||
| - ptf64: as ptf32, but with 64 ports | ||
| - t0: 4 VMs + ptf. PTF container has 4 injected ports + 28 directly connected ports |
