When sending BGP routes in an Update message, how are they grouped?

Refer to the Exhibit.

You work for the regional Internet service provider shown in the exhibit. You have a partial BGP
table and are receiving a 10.100/16 route from your upstream ISP. You have been asked to
configure a default route that can be sent to your downstream customer. This route should forward
customer traffic toward your upstream Tier 1 ISP as long as the 10.100/16 route is present.
What would accomplish this goal?
