In this video, I'll show you the basic configuration required in order to get MPLS up and running on a network made up of Cisco devices. We'll also examine how the CE and PE routers are configured to allow the MPLS network to learn about customer networks. In this video, we'll be configuring a topology with three Autonomous Systems (ASes). BGP will be used as the routing protocol between the PE and CE routers. The MPLS infrastructure will use OSPF as the IGP within its AS, as well as an iBGP peering between the PE routers themselves. If you need to brush up on your BGP, you can take a look at my BGP playlist of videos that includes all the information you'll need to know. I've also included some specific BGP videos that are relevant to the topology we'll be deploying. In this video series on MPLS, you’ll learn where MPLS fits within the broader networking landscape, the problems it was designed to solve, and the key benefits it offers, such as improved traffic management, scalability, and support for multiple services. ☑️ Chapter list: ============================================ 00:00 Introduction 00:27 The MPLS Topology 02:29 CE-PE Routing 03:46 OSPF Underlay 05:34 iBGP Peerings between PEs 06:50 The MPLS Configuration 07:54 Configuration Verification 10:17 Summary 🟩 Related Videos and Links: =============================================== MPLS - What is it? - https://youtu.be/vBi4T5dl_YM MPLS - Understanding Labels, Device Roles, and LDP - https://youtu.be/iLqFKXdgvYw MPLS - Understanding the Label Distribution Protocol (LDP) - https://youtu.be/dA3V8MMSqKc MPLS - Pushing, Swapping, and Popping labels - https://youtu.be/wY6I_74gGfc MPLS - Using BGP in the MPLS Core - https://youtu.be/HcaI7p15uJ8 BGP - iBGP vs eBGP - What's the difference? - https://youtu.be/3x7yztGSY-g BGP - Why does iBGP require full mesh peering? - https://youtu.be/03Gl1YGeZYc BGP - why does BGP need an IGP to function? - https://youtu.be/SN_TDZ2eDAA BGP - Video Series Playlist - https://www.youtube.com/playlist?list=PLmVr8r1kmMm0ncoc9L6bFICpuNbo7Tumu 🟦 About ============================================== Welcome to telecomTech, where telecom and networking technologies... are simply explained!
