MPLS: Power and Complexity

Oscar Cetina, a Network Engineer at Foxtel, shares his expertise on network expansion and migration projects utilizing MPLS technology. With a professional background in Telecommunications and certifications including CCNA and CCNP, Oscar discusses the complexity and advantages of MPLS in enhancing connectivity. He addresses the importance of protocols like OSPF, BGP, and the use of VRF for tailored routing solutions. Oscar also highlights the challenges of QoS implementation and emphasizes the need for specialized knowledge in the design, implementation, and troubleshooting of complex network systems.

  7. Network Expansion/Migration Project OSPF EIGRP BGP RIP MPLS

  8. MPLS Constraints/Complexity • Requires (IGP) OSPF and BGP to work • Requires VRF (Virtual Routing Forwarding) to work • Creates more than 5 routing/switching tables • Specialised knowledge to design, implement and troubleshoot Advantages/Power • Minimal migration disruption if well-planned • Does not require changes on the existing routing protocols/IP address allocation • Easy integration regardless vendors or protocols • Ideal for customization: Offers virtual/customised routing for a great deal of customers in 1 device when configured through VRF (MPLS/VPN) • Simple from the user perspective (compare to smartphones) Challenges • QoS implementation, even more complex due to mapping mismatch from the IGP • Adding features to simplify particular services • Control and monitoring of MPLS devices
