The Cidr Report

  Does this call into question the idea that there is a
  single "default-free" view of the Internet?

Of course. Contents of a default free routing table will
depend on the filters on between you and who is originating
the routes (incl. broken filters givin leaks of more
specifics, deliberate filters cf Sprint on prefix
length or those who build from the RA) and on any
proxy aggregation that might happen on the way. As the
original conjecture was that many routes "didn't
need to be there" its hardly surprising that quite
a lot of routes are carried by neither AGIS, Sprint
or UUnet and things still carry on working (in general).

  My box is attempting to collect a view of the routing
  system as seen at a particular point in the topology.
  While this may not be interesting to Randy, others
  might find it useful.

  I would be interested in tracking the views as seen at
  a number of different places in the topology. The deltas
  between the growth in the number of widely dispersed routes
  vs the local varience would be an interesting number to

There is a collector router at the LINX IXP in London UK which
3 of us give transit to and everyone else there gives peer
style routes to. You might ask Keith Mitchell (
if you can have an EBGP multihop from that for collection
