Facebook went dark, and many said it was because of BGP. But what is this protocol that’s making the internet possible, how does it work, and how can it cause one of the biggest services to drop offline?
BGP is a routing protocol. Here is a simple definition of network routing from John F. Shoch, an American computer scientist who developed the predecessor toTCP/IP: “Thenameof a resource indicates what we seek, anaddressindicates where it is, and aroutetells us how to get there”. The B...
NVA or a BGP end point provisioned in a virtual network connected to a virtual hub, can directly peer with the virtual hub router if it supports the BGP routing protocol and ensures that ASN on the NVA is set up to be different from the virtual hub ASN....
This document describes the Border Gateway Protocol (BGP) Resource Public Key Infrastructure (RPKI) feature on the Cisco IOS® XR Platform. Background Information Preface This document discusses the BGP RPKI feature and how it safeguards BGP with routers against false/malicious BGP p...
Implementing BGP Border Gateway Protocol (BGP) is an Exterior Gateway Protocol (EGP) that allows you to create loop-free interdomain routing between autonomous systems. An autonomous system is a set of routers under a single technical administration. Routers in an autonomous system can use multiple...
Accordingly, the proposed controller is designed such that the key feature of the proposed mechanism is that it could be real time implemented to solve the traffic redistribution problem without any change in both BGP protocol and running internet infrastructure. 3. BGP novel control mechanism (BGP...

According to the protocol specification, a BGP speaker should not issue an update containing the same BGP information as was most recently advertised for the prefix. However such redundant messages, called duplicate updates, have been observed as early as 1998 [LMJ98]. The authors noted that the...
The issue we have without add-path is that the traffic distribution is on a per-node basis, not a per-pod basis. So if you have multiple pods for a service on a single node, it can lead to traffic imbalances, as explained in more detail athttps://metallb.universe.tf/usage/#local-...
. Also, the above Internet draft includes a use of the non-transitive MED attribute to convey IGP metrics to the BGP advertisements400. Again, these previously defined attributes are non-transitive, and, as such, may not be used properly when the PE-CE protocol is BGP, as explained above....
