I must have missed the request for "one compelling reason" for CPE  
routers to send and receive RFC 4191 more specific route information  
messages on their WAN links.  My apologies.

Please let me clarify my remarks and narrow my request somewhat, now  
that I've had a chance to review more of the CPE Router draft.  I am  
only interested in such RFC 4191 messages when a valid PIO has been  
received on the WAN link with L=1.  No other cases are interesting.

The reason I want this should be obvious: so that a CPE router may  
advertise its local prefix on the WAN link to other nodes so as to  
eliminate the need for traffic that originates from them to have to  
hairpin through their default router to be delivered.
