  Preface:   From a network architect’s point of view, VRF Lite, PBR and SD-WAN gives you a super flexible, secure and performance optimized WAN architecture. VRF Lite gives you logical segmentation on shared infrastructure so you can keep sensitive departments like Finance isolated without having to deploy separate physical links. PBR gives you precise rule-based traffic steering at specific sites - ideal for enforcing static business policies like forcing ERP traffic onto MPLS or keeping guest Wi-Fi on broadband even in non-SD-WAN locations. SD-WAN is the overarching intelligent WAN fabric that gives you centralized control, application aware routing and dynamic path selection to optimize performance for real-time and cloud-based applications. Together they give you granular control, robust security segmentation and agile traffic optimization across a hybrid WAN that aligns to your compliance needs and evolving business performance requirements.

Preface: Orange, a global telecoms company, uses EDIA (Ethernet Dedicated Internet Access) at its HQs in London , Berlin and Paris to ensure each site has guaranteed, high-speed and low-latency internet for critical business apps like Office 365, cloud collaboration tools and secure remote access. These EDIA circuits provide dedicated bandwidth with SLA-backed performance so they’re perfect for HQs that can’t afford downtime or performance degradation. For its branch offices and regional sites across Europe, Orange has a Hybrid WAN architecture where MPLS lines (for latency-sensitive traffic like VoIP and internal systems) and broadband/EDIA connections (for general internet traffic) are combined through an SD-WAN platform , so traffic is intelligently routed and fails over seamlessly during outages. Orange also connects its data centers in Paris and Berlin with EVPN-VXLAN links over its MPLS backbone , so there’s Layer 2 and Layer 3 connectivity between virtualized environm...
