We have been discussing some multi-homing scenarios at the ietf which
may turn out to correspond in part to the problem telstra is attempting
to solve. Geoff gave a presentation which describes some of this, which
you will find at http://www.merit.edu/~ahuja/ (look at the bottom for
the ptomaine stuff).
The basic issue is to find a mechanism whereby someone at the edge of the
network can pass policy to their peers and providers, and have that policy
propagate reliably.
The solution of advertising a large number of prefixes in different ways
to different adjacent networks is one way of accomplishing the policy
dissemination; however, one problem is the large amount of prefix bloat
associated with it that the whole network gets to see.
The ptomaine, multi6 and idr working groups all seem to be looking at
bits and pieces which are relevant to this.
