Redesigning ESI's data center from a legacy 3-Tier network to a Leaf-Spine fabric with VXLAN/BGP EVPN overlay, eBGP+ECMP underlay, and full security hardening — validated in an EVE-NG lab.

Infrastructure multi-datacenters validée reposant sur un maillage full-mesh et une stratégie de défense en profondeur hybride. -Sécurité Multi-Vendeurs : Combo Cisco ASA (Périmètre/NAT) et Fortinet FortiGate (Inspection avancée/Deep SSL). Utilisation de Reverse Proxies Apache (mod_proxy) pour l'isolation et le front-end applicatif. -Routage : eBGP

BGP exploration and the process of setting up a BGP network within an Autonomous System (AS), including BGP configuration, route advertisement, and path selection mechanisms. It covers real-world BGP implementations, security best practices, and network optimizations to enhance routing efficiency and prevent common vulnerabilities.

GNS3 network lab implementing OSPF routing and eBGP interconnection between autonomous systems using MikroTik RouterOS and Debian hosts.
