Podcast: Play in new window | Download (68.6MB)
Border Gateway Protocol (BGP) is a protocol that makes the Capitl I Internet run. It is the fundamental system that Internet Service Providers (ISPs) and large networks use to exchange reachability information and ensure data finds its way across the complex web of networks making up the global Internet.
MikroTik vs Cisco: How BGP varies between platforms. The 10,000 foot view
MikroTik vs Cisco: How BGP Works on Each Platform When it comes to Border Gateway Protocol (BGP), both MikroTik and Cisco routers offer powerful capabilities to participate in dynamic interdomain routing. However, there are some significant differences in configuration syntax, defaults, feature sets, and operational behavior between the two platforms. Whether you’re migrating between them … Read more
BGP Filtering Best practices for fun and security
Border Gateway Protocol (BGP) filtering is critical for securing and optimizing internet routing. Improper BGP configuration can lead to serious issues like route leaks, hijacks, or suboptimal routing. Here are the most effective best practices for BGP filtering: 1. Prefix Filtering Objective: Ensure only authorized prefixes are advertised or accepted. 2. AS-PATH Filtering Objective: Prevent … Read more

Understanding How TCP/IP Works: A Beginner’s Guide
The TCP/IP (Transmission Control Protocol/Internet Protocol) is the backbone of the internet and most modern networks. It ensures that data is transmitted reliably and efficiently between devices, whether you’re sending an email, streaming a video, or browsing a website. In this blog, we’ll break down how TCP/IP works, its layers, and how data moves across … Read more
What is the Global BGP Routing Table?
The Global BGP Routing Table is a comprehensive database that contains all the IP address prefixes (routes), which are advertised by ASNs, and the associated paths to reach them across the internet.
Understanding Autonomous System Numbers (ASNs) in BGP
A critical component of BGP’s functionality is the Autonomous System Number (ASN). But what exactly is an ASN, and why is it so important?
How Route Servers Work on an Internet Exchange Point (IXP)
In the world of Internet connectivity, Internet Exchange Points (IXPs) play a crucial role in facilitating efficient traffic exchange between networks. Within this ecosystem, route servers act as intermediaries to streamline the process of establishing connections, known as peering, between multiple networks. Here’s an overview of how route servers work and why they are vital … Read more
Navigating the Complexity of Full BGP Routes: A Deep Dive into Border Gateway Protocol
In networking and internet connectivity, the Border Gateway Protocol (BGP) stands out as a crucial protocol responsible for routing data packets across the vast expanse of the internet. At the heart of BGP lies the concept of routing tables, and within that domain, the notion of full BGP routes takes center stage. In this blog … Read more
