BGP - What are iBGP Route Reflectors?
A Route Reflector (RR) is an iBGP router that acts as a centralized route management point within an AS. It is a method of overcoming the scalability problem that the iBGP full mesh peering requirement introduces into an AS. In this video, I will delve deep into what RRs are, how they operate, and how they overcome the limitations of scalability inherent to iBGP peerings.
If you want to find out more about the BGP routing protocol, or the method by which attributes are used to determine the best path, and other interesting features of the protocol, take a look at some of my other videos linked below (after the chapter list...)
