Advanced Implementing and Troubleshooting MPLS VPN Networks

Powerful 5 Day Course

Course Description

Advanced Implementing and Troubleshooting MPLS VPN Networks Boot Camp is a comprehensive five-day hands-on course that will enable you to develop the skills to successfully deploy a complex MPLS VPN installation with significant focus on troubleshooting common problems. You will explore the intricacies of the benefits of an MPLS VPN solution, the common pitfalls, and the best practices for implementing MPLS VPN.

Eight in-depth hands-on labs ensure that you learn the theory as well as the practical skills. You will learn how to build intranet and extranet MPLS VPN networks, add Internet access, and then migrate this complex network into multiple autonomous systems (ASs) where Inter-AS VPNs and Carrier Supporting Carrier (CsC) VPNs are supported. .

Course Labs

• Lab 1: Configuring Router and IP Connectivity
  Explore your classroom lab environment including familiarizing yourself with the classroom routers, lab topology, current configurations, and current routing.
• Lab 2: Configuring and Verifying MPLS
  Build from Lab 1 by configuring an MPLS infrastructure and verifying that MPLS label switching is functioning properly.
• Lab 3: Configuring Intranet MPLS VPNs
  Introduce VPNs into the classroom network. Configure and verify VRF on PE Routers, CE to PE routing using static routes, CE to PE routing using RIPv2, CE to PE routing using eBGP, and CE to PE routing using OSPF.
• Lab 4: Migrating to VPNv4 Route Reflectors
  Establish VPNv4 peering between the router reflector and PE and Autonomous Systems Border Router (ASBR) routers.
• Lab 5: Interconnecting MPLS VPNs between Ass
  Explore on a basic network some methods for interconnecting MPLS VPNs between autonomous systems.
• Lab 6: Creating Complex Inter-AS MPLS VPNs
  Building from Lab 5, connect that simple network back into a large real-world network dealing with real-world issues. Reconnect the POPs and reestablish iBGP peering relationships. Establish a VPNv4 MP-eBGP multi-hop peering session between new RRs. Create leak only loopback addresses to a remote AS. Finally, verify that inter-AS VPN routing is operating correctly.
• Lab 7: Configuring Carrier Supporting Carrier (CsC)
  Implement CsC in the classroom by first configuring MPLS on the PE interface to the CE. Next, configure MPLS on the CE interface to the PE. Configure CE to CE routing. Configure external network advertisements. Finally, verify a successful implementation by loopback interfaces.
• Lab 8: Configuring MPLS VPN Internet Access
  Implement various methods of Internet access using MPLS VPNs including Internet Access with Route Leaking, Shared Access through Internet VRF, and Full Internet Routing in CE.
