BGP - Understanding BGP Confederations
BGP Confederations essentially allow us to create sub-autonomous-systems within an autonomous system, thus creating a hierarchical structure to a large AS. Confederations are a method of overcoming the scalability problem that the iBGP full mesh peering requirement introduces into an AS. In this video, I will describe confederations, how they function, and how they can be used to overcome the limitations of scalability inherent to iBGP peerings.
