    What MPLS L3 VPN? | MPLS VPNv4 peering | MPLS LDP peering | How to configure MPLS L3 VPN Static?

    Internetworks April 12, 2025

     MPLS Layer 3 VPN (L3VPN) is a technology that enables service providers to offer secure and scalable IP-based VPN services to customers. It uses Multiprotocol Label Switching (MPLS) to route traffic efficiently while maintaining separation between different customer networks.

    A static MPLS L3VPN typically refers to a setup where static routes are used instead of dynamic routing protocols like BGP or OSPF. This approach can be simpler to configure but may lack flexibility compared to dynamic routing.

    Here are some key components of MPLS L3VPN:

    • VRF (Virtual Routing and Forwarding): Allows multiple routing tables on a single router.
    • MP-BGP (Multiprotocol BGP): Used to exchange VPN routes between provider edge (PE) routers.
    • Route Distinguisher (RD): Helps differentiate overlapping IP addresses between customers.
    • Route Target (RT): Defines which VPN routes should be imported/exported.
    let's see the configuration:

    Topology:-


    1. Configure the topology as per the diagram 
    2. Configure the IP addresses as per the topology
    3. Configure EIGRP AS 65100 inside the MPLS CORE network
    4. Ensure the connectivity inside MPLS CORE
    5. Configure MPLS LDP Peering 
    6. Create VRF A-1 for site 1 and VRF A-2 for site 2 (R1&R3)
    7. Create route distinguisher value 500:1
    8. Create route-target for both import and export value 500:1
    9. Apply this on both sites
    10. Configure route 1 fa0/0 under VRF A-1
    11. Configure route 2 fa0/0 under VRF A-2
    12. Configure default route on routers 5 and 4
    13. Configure routing between PE and CE routers
    14. Configure BGP VPNv4 peering

    How to configure MPLS LDP Peering ?

    Internetworks January 14, 2020


    Label distributing protocol (LDP) is a protocol that automatically generates and exchanges labels between MPLS routers. Each MPLS router will locally generate labels for its prefixes and then it will advertise the label values to its neighbors.



    before we start our we must be familiar with these topics :

    1. 1. Introduction of MPLS

      2. What is MPLS Label distributing protocol (LDP)? How LDP works?

      3. how to configure MPLS LDP Peering?

      4. What is MPLS L3 VPN? How to configure?

      5. How to configure MPLS L3 VPN with RIPv2?

      6. How to configure MPLS L3 VPN with EIGRP?

      7. How to configure MPLS L3 VPN with OSPF?

      8. What are OSPF Sham Links? how to configure OSPF Sham Links?

      9. How to configure MPLS L3 with BGP AS OVERRIDE?

      10. What Is Network Tunneling And How To Configure Generic Routing Encapsulation (GRE) Tunnels?

      11. What Is DMVPN (Dynamic Multipoint VPN), NHRP, MGRE, And How To Configure DMVPN Phase 1?

      12. What Is DMVPN (Dynamic Multipoint VPN) Phase 2? How To Configure DMVPN Phase 2 Dynamic And Static Mapping?

       13. How To Configure EIGRP And OSPF Over DMVPN Phase 1 & 2?

       14. How To Configure External BGP And EIGRP On DMVPN Phase 2?

      15.  What Is IPSec (Internet Protocol Security)? What Is Internet Key Exchange IKE? How To  Configure IPSec Tunnel?

      16. What Is IKE (Internet Key Exchange)? How To Configure IPSec Site-To-Site?

       

       



    We will see many show commands do not skip it.  Let see the configurations:  

    Topology:-


    Task:
    • configure the topology as per the diagram 
    • assign the IP addresses as per our topology.
    • configure IGP EIGRP inside our MPLS network.
    • advertise directly connected interfaces and loopbacks interfaces 
    • configure MPLS on all our routers with LDP 
    • configure the labels 
    • enable IP cef
