And this is the bit that worries me a lot - ISPs come in all shapes and
sizes - what is an ISP from one perspective is a customer from another.
There is no 'top down' enforcement model that I am aware of that creates
integrity in the area of route advertisements. This implies that the
level of trust that one can ascribe to ISPs is inadequate in terms
of ensuring that routes are 'valid' and 'correct' at all times.
