BGP route reflectors have been supported in Cisco IOS well before I started to develop the first BGP course for Cisco more than a decade ago (one of the early ABCT course descriptions is still available online thanks to the Wayback machine). It’s a very simple feature, so I was pleasantly surprised when I started digging into it and discovered a few rarely known details. Read all about the BGP route reflector details in the article I wrote in the CT3 wiki.
