Typically you would only originate default via BGP to a customer that
isn't taking a full view.
neighbor 10.10.10.2 default-originate
neighbor 10.10.10.2 filter-list 9 out
ip as-path access-list 9 deny ^.*$

In the example above the default originate is done via a specific BGP
session, so it isn't router wide on either core or border routers.
