+PVP L3 Router Internal Chain
+--------------
+
+NFVbench can measure the performance of 1 L3 service chain that are setup by NFVbench (VMs, routers and networks).
+
+PVP L3 router chain is made of 1 VNF (in vpp mode) and has exactly 2 end network interfaces (left and right internal network interfaces) that are connected to 2 neutron routers with 2 edge networks (left and right edge networks).
+The PVP L3 router service chain can route L3 packets properly between the left and right networks.
+
+To run NFVbench on such PVP L3 router service chain:
+
+- explicitly tell NFVbench to use PVP service chain with L3 router option by adding ``-l3`` or ``--l3-router`` to NFVbench CLI options or ``l3_router: true`` in config
+- explicitly tell NFVbench to use VPP forwarder with ``vm_forwarder: vpp`` in config
+- specify the 2 end point networks (networks between NFVBench and neutron routers) of your environment in ``internal_networks`` inside the config file.
+ - The two networks specified will be created if not existing in Neutron and will be used as the end point networks by NFVbench ('lyon' and 'bordeaux' in the diagram below)
+- specify the 2 edge networks (networks between neutron routers and loopback VM) of your environment in ``edge_networks`` inside the config file.
+ - The two networks specified will be created if not existing in Neutron and will be used as the router gateway networks by NFVbench ('paris' and 'marseille' in the diagram below)
+- specify the router gateway IPs for the PVPL3 router service chain (1.2.0.1 and 2.2.0.1)
+- specify the traffic generator gateway IPs for the PVPL3 router service chain (1.2.0.254 and 2.2.0.254 in diagram below)
+- specify the packet source and destination IPs for the virtual devices that are simulated (10.0.0.0/8 and 20.0.0.0/8)

+ gateway_ip_addrs: ['1.2.0.1', '2.2.0.1']

+ left:
+ name: 'lyon'
+ cidr: '1.2.0.0/24'
+ gateway: '1.2.0.1'
+ right:
+ name: 'bordeaux'
+ cidr: '2.2.0.0/24'
+ gateway: '2.2.0.1'
+
+ edge_networks:
+ left:
+ name: 'paris'
+ cidr: '1.1.0.0/24'
+ gateway: '1.1.0.1'
+ right:
+ name: 'marseille'
+ cidr: '2.1.0.0/24'
+ gateway: '2.1.0.1'
+
+Upon start, NFVbench will:
+- first retrieve the properties of the left and right networks using Neutron APIs,
+- extract the underlying network ID (typically VLAN segmentation ID),
+- generate packets with the proper VLAN ID and measure traffic.
+
+
+Please note: ``l3_router`` option is also compatible with external routers. In this case NFVBench will use ``EXT`` chain. \ No newline at end of file
