Many organizations using BGP for reliable Internet connectivity will never grow beyond a small handful of routers running BGP. Even an AS with hundreds of internal routers may only need two or three border routers running BGP. Indeed, if firewalls are used, it may be desirable to limit the number of border routers to two or three. Other organizations will want to have dozens to hundreds of BGP-speaking border routers. Many of these organizations are ISPs.
As the number of border routers goes up, issues arise that're not present in smaller networks. Chapters in this part deal with managing IBGP complexity and special features for transit providers.
