It also provides the possibility to deliver different +services for the customers in a seamless manner. +Layer 3 VPN (L3VPN) is a type of VPN mode that is built and delivered +through OSI layer 3 networking technologies. Often the border gateway +protocol (BGP) is used to send and receive VPN-related data that is +responsible for the control plane. L3VPN utilizes virtual routing and +forwarding (VRF) techniques to receive and deliver user data as well as +separate data planes of the end-users. It is built using a combination of +IP- and MPLS-based information. Generally, L3VPNs are used to send data +on back-end VPN infrastructures, such as for VPN connections between data +centres, HQs and branches. + +An L3VPN consists of multiple access links, multiple VPN routing and +forwarding (VRF) tables, and multiple MPLS paths or multiple P2MP LSPs. +An L3VPN can be configured to connect two or more customer sites. +In hub-and-spoke MPLS L3VPN environments, the spoke routers need to have +unique Route Distinguishers (RDs). In order to use the hub site as a +transit point for connectivity in such an environment, the spoke sites +export their routes to the hub. Spokes can talk to hubs, but never have +direct paths to other spokes. All traffic between spokes is controlled +and delivered over the hub site. + + +To deploy a Layer3 VPN with MPLS on VyOS, we should meet a couple +requirements in order to properly implement the solution. +We'll use the following nodes in our LAB environment: + +* 2 x Route reflectors (VyOS-RRx) +* 4 x Provider routers (VyOS-Px) +* 3 x Provider Edge (VyOs-PEx) +* 3 x Customer Edge (VyOS-CEx) + +The following software was used in the creation of this document: + +* Operating system: VyOS +* Version: 1.4-rolling-202110310317 +* Image name: vyos-1.4-rolling-202110310317-amd64.iso + +**NOTE:** VyOS Router (tested with VyOS 1.4-rolling-202110310317) +– The configurations below are specifically for VyOS 1.4.x. + +General information can be found in the :ref:`l3vpn-vrfs` chapter. + + + +******** +Topology +******** +.. image:: /_static/images/L3VPN_hub_and_spoke.png + :width: 80% + :align: center + :alt: Network Topology Diagram + + + +***************** +How does it work? +***************** + +As we know the main assumption of L3VPN “Hub and Spoke” is, that the traffic +between spokes have to pass via hub, in our scenario VyOS-PE2 is the Hub PE +and the VyOS-CE1-HUB is the central customer office device that is responsible +for controlling access between all spokes and announcing its network prefixes +(10.0.0.100/32). VyOS-PE2 has the main VRF (its name is BLUE_HUB), its +own Route-Distinguisher(RD) and route-target import/export lists. +Multiprotocol-BGP(MP-BGP) delivers L3VPN related control-plane information to +the nodes across network where PEs Spokes import the route-target 60535:1030 +(this is export route-target of vrf BLUE_HUB) and export its own route-target +60535:1011(this is vrf BLUE_SPOKE export route-target). Therefore, the +Customer edge nodes can only learn the network prefixes of the HUB site +[10.0.0.100/32]. For this example VyOS-CE1 has network prefixes +[10.0.0.80/32] / VyOS-CE2 has network prefixes [10.0.0.90/32]. +Route-Reflector devices VyOS-RR1 and VyOS-RR2 are used to simplify network +routes exchange and minimize iBGP peerings between devices. + +L3VPN configuration parameters table: + ++----------+-------+------------+-----------------+-------------+-------------+ +| Node | Role | VRF |
