Iljitsch van Beijnum, author of the book BGP: Building Reliable Networks with the Border Gateway Protocol https://www.oreilly.com/pub/au/970 discusses internet routing and BGP – the border gateway protocol used by ISPs to update routing information. Host Robert Blumen spoke with Iljitsch about the topology of the internet, autonomous systems (AS), regulatory bodies that coordinate the AS space, IP addresses, the assignment of IPs to ASs; tier-one ISPs, carriers, and home/business ISPs; Internet routing; the path of a packet; routing tables, what they contain, and how they are constructed; routing algorithms; BGP and its role in updating routers with the knowledge of routes held by other routers; and BGP messages. Drill down into the update message. How updates progress from BGP into routing algorithms and then routing tables. What can go wrong. Attacks on BGP.
