Providing Customers Internet Connectivity using BGP

About this course

This course offers an in-depth exploration of how customer networks connect to internet service providers (ISPs) to enable critical applications like intranet VPNs, extranets, and broader internet access. You will gain practical knowledge on designing and implementing network connectivity considering physical connection types, redundancy, IP addressing, and autonomous system (AS) numbering to meet both business and technical needs. The course uniquely covers static routing for single and multiple connections to a single ISP, and advances to multihomed strategies using multiple ISPs for maximum redundancy. You will explore configuring routing protocols—especially BGP—to support backup links, load balancing, and proper interaction between customer and provider networks. Additionally, the course tackles scalability challenges in complex service provider environments, addressing IGP and BGP interactions and IP addressing that ensure network stability and efficiency. With a comprehensive curriculum including videos, readings, and hands-on assignments, this course equips network designers and administrators with the expertise to build robust, scalable, and resilient internet connectivity solutions. Its focus on real-world configurations and multilevel connectivity makes it an essential learning experience for professionals aiming to excel in modern network design and management.
