In recent years, the concepts of Artificial Intelligence (AI) and Machine Learning (ML) have moved from the academic realm to the forefront of many industries. The networking world, in particular, has started to explore ways to harness these...
Nowadays, the very abstract ideas underlying the quantum physics are being translated into reality thanks to new technological capabilities in the field of...
This blog post discusses BGP Labeled Unicast (BGP-LU) which is used in multi-regional networks to carry the label information. While the RFC3107 “Carrying...
The aim of this article is to discuss the importance of Recursive Lookup in BGP. First of all we need to understand the purpose of the recursion method and...
RFC 7311 defines an optional non-transitive BGP attribute called the Accumulated IGP Metric Attribute (AIGP). As we know, IGP stands for Interior Gateway...

The unstable route whose availability alters repeatedly is called a flap. When flaps occur, an excessive number of BGP UPDATE messages are sent to BGP peers...
The BGP Attribute Filter feature enables BGP speakers to take a certain action based on the presence of a specified path attribute inside the UPDATE message...
Full iBGP Mesh and Route Reflection To avoid loops in a Full iBGP Mesh, BGP routers are only allowed to learn prefixes over iBGP from the router that...
Network Address Translation (NAT) was originally described in RFC 1631. Although initially presented as a short term solution for preventing the IPv4...
The BGP advertisement of a prefix with new attributes replaces the previous announcement of that prefix. This behavior is known as an Implicit Withdraw, which...
In this blog post, we will take a look at Kevin Myers's presentation where he discusses deployment of both OSPF and BGP routing protocols in order to select...
