On August 30, 2020, Level 3/Century Link, AS 3356 had major Internet outage. In fact this outage effected massive amount of networks, including very well know ones such as Amazon, Microsoft, Twitter, Discord, Reddit etc.
BGP Confederation is specified in RFC 5065, which describes the use of Autonomous System Confederations for BGP – Border Gateway Protocol.
BGP Route Server is used at the Internet Exchange Point to simplify BGP Peering process. Instead of managing, maintaining hundreds of Peering sessions in large Internet Exchange Point, BGP Route Server is used.
When it comes to Routing Security, BGP Origin and Path Validation should be understood very well.
Internet Exchange Point Design and Deployment in Real Life, this is one of the most confidential topics in networking.
Autonomous System Provider Authorization – ASPA is a new approach for the Path Validation in BGP Information Security.
BGP Convergence and ASn allocation design in Large Scale Networks covered in this post and the video at the end of the post.
BGP+SPF Imagine we replace BGP best path selection decision with SPF. BGP+SPF exactly does that. In this post, I will explain why we are looking for alternative protocols for Massively Scale Datacenter.
RIFT – Routing in Fat Trees. RIFT is a Routing Protocol which is targeted for Densely Meshed topologies such as Fat Tree. Tony Przygienda who is the inventor of RIFT, Jeff Tantsura and Orhan Ergun are discussing below questions about RIFT routing protocol.
BGP PIC Fundamentals: BGP PIC ( Prefix Independent Convergence ) is a BGP Fast reroute mechanism which can provides sub second convergence even for the 800K internet prefixes by taking help of IGP convergence.
