MPLS VPNv4 Backbone Config Explained

In this video, I will show you how to configure the P and the PE routers on an ISP's MPLS backbone infrastructure to support VPNv4 routes. I'll show you how to employ the underlay IGP, MP-BGP, VRFs, RDs and RTs in preparation for allowing customer networks to connect over the ISP MPLS backbone. This is the first video of a three-part miniseries describing the configuration and verification of VPNv4 routes over MPLS. In this first part, we'll be configuring the backbone ISP network. In the next video, we'll complete the configuration by bringing in the CE routers as well, and in the third video, we'll verify and examine VPNv4 routes, see how they are exchanged, and see how VPN labels are used. So stay tuned for those! 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. 🟥 SUBSCRIBE: https://shorturl.at/TTJxx Chapter list: ============================================ 00:00 Introduction 00:47 The MPLS Topology 02:18 Configuring the Underlay 04:55 Enabling MPLS 05:50 Creating VRFs 09:35 Configuring and Enabling MP-BGP 11:29 Summary 🟩 Related Videos and Links: =============================================== MPLS - Using BGP in the MPLS Core - https://youtu.be/HcaI7p15uJ8 MPLS - RDs, RTs, and VPNv4 Routes - https://youtu.be/R8e4vvFmgUo MPLS - Understanding Virtual Routing and Forwarding (VRF) - https://youtu.be/_zjH0o1RlKI BGP - Video Series Playlist - https://www.youtube.com/playlist?list=PLmVr8r1kmMm0ncoc9L6bFICpuNbo7Tumu 🟦 About Welcome to telecomTech, where telecom and networking technologies... are simply explained!
