In MPLS Layer 3 the service provider will participate in routing with the customers. The customers will run static, OSPF, EIGRP, BGP, or any other routing protocol with the service provider; these routes can be shared with other sites of the customers.
In VPN routing information from one customer is completely separated from other customers and tunneled over the service provider MPLS network.
we have already discussed what is MPLS? how MPLS work? and What is MPLS L3 VPN ? in this section we see how to configure MPLS L3 VPN supports RIPv2. Before we start our configuration you must familiar with these topics.
Let see the configuration to get a better understanding:-

Let see the configuration to get a better understanding:-
Topology:
Goal:
- configure the topology as per the diagram
- assign the IP addresses to their interfaces
- configure IGP (EIGRP 65100) inside MPLS SP core
- configure MPLS LDP on router 1_2_3
- configure labels (99-199_200-299_300-399)
- configure VRF a-1 on router 1 and VRF a-2 on router 3
- configure RD and RT value 100:1 on both the sites
- configure on router 1 assign FastEthernet facing CE under VRF a-1
- configure on router 3 assign FastEthernet facing CE under VRF a-2
- configure RIPv2 on both CE routers
- make sure PE and CE routers can ping
- configure VPNv4 between PE routers.
- redistribute RIPv2 routing into BGP under VRF
- make sure CEs routers able to ping
