F's covering prefix, 192.5.5.0/24, is advertised to peers of F-root  
local nodes with NO_EXPORT. 192.5.5.0/24 is advertised to peers of AS  
3557 without NO_EXPORT.

A shorter prefix, 192.5.4.0/23, is also advertised without NO_EXPORT  
from AS 3557.

In the cases where local nodes of F advertise 192.5.5.0/24 with  
NO_EXPORT to ASes which also provide transit for 3557, we have taken  
care to ensure that local policy in those ASes causes the 3557 route  
(a customer route) always to be selected in preference to that  
received from the local node (a peer route). In these cases the local  
node provides local backup service.

A description of F's deployment strategy can be found in <http:// 
www.isc.org/pubs/tn/isc-tn-2003-1.html>.
