Most RX side bgp (from helping out a small regional) was done to reduce
their cost to their primary transit provider (turning on peering with
networks behind say, 701, would allow them to shortcut 701)  and to
provide a bgp feed to a few customers. Things like filtering everthing
except _701_ and _1239_ and _1_ on various links were used to achieve a
measure of traffic engineering on their links (outbound). They really
could have gotten away with using a default out.
