If your customer is merely using the deaggregates for TE, why would
they need to send the deags with anything but no-export. This
would resolve the issue of having to advertise them to your peers,
while still allowing the customer to have traffic come in whichever
link they chose. The added benefit is that no one else needs to accept
additional routes.
