I guess I look at it like this: if you can't think of a clever,
reliable and robust way of filtering out the traffic for the current
model then how does adding extra layers, complexity and latency allow
you to do any better? You'll still need to be able to do the same
filtering, in the same way on the same kind of routers in your model, so
you don't seem to have improved things by adding the complexity.
ie. how would I solve the /22 into transit, /24 more specifics via MLPA
any better in your model? What extra control and nerd knobs do I get?
The issue of MLPAs breaking the usual "we won't peer with customers"
practise (and clearly for good reason) is a commercial issue not a
technical one - so the solution maybe more commercial than technical but
with some careful monitoring of what we're seeing?
Internet transit is different to Intranets - global connectivity is
assumed, not optional which leads to very different solutions.
