Abstract: Each point-of-presence advertises the network addresses it hosts and the network addresses hosted by other points-of-presence. Each point-of-presence also announces its own network addresses at a higher degree of specificity than the other network addresses it is announcing. When a point-of-presence fails, packets routed to a network address hosted by that point-of-presence will be routed to one of the other points-of-presence announcing the same network address. When a point-of-presence is available, its more specific network address announcements prevents packets routed to a network address hosted by that point-of-presence from being routed to any other point-of-presence.
