Answer to Question 12, the explanation is confusing. for clarification:
The question was to make sure the reader understood that the routing bit was internal to the PE router and not sent
to the customer.

If the down bit is set the routing bit is cleared.

A better answer is: Routing updates from a PE router to customer routers do not contain a routing bit. A routing bit is an internal mechanism on the PE. When a route is received on the PE router with the downbit the routing bit is cleared (meaning it will not show up in the routing table or be used).
