In this Lab, I am using GNS3 to redroduce the book "MPLS Configuration on Cisco IOS Software" p95 Figure 3-11 Lab.
Scenario:
This lab outlines the generic confgurations required on the routers in the service provider domain to implement MPLS VPN.
Configuration steps
1. Confguration of CE Routers
2. Confguring MPLS Forwarding and VRF Defnition on PE Routers
3. Confguration of BGP PE-PE Routing on PE Routers
4. Confguration of P Router
1. Confguration of CE Routers
