What do you mean with the above? If I understand the line correctly, then I disagree with it.

IMHO generally ones network infrastructure is pretty aggregated internally already as the physical structure is most likely also a star/bus topology which fans out towards the endusers, while the core is where you connect to the Internet. When you have 'home users' and even residential users they generally get connected to a PoP for a certain neighborhood. Generally these users won't move around the country. As such, just give the PoP a /40 or whatever you need to serve the users from that site. This keeps the number of internal routes low. Now if you have a well paying customer who wants to take their /48 along, just announce the more specific in iBGP. Of course never announce a de-agg of the allocation you received into eBGP.

Or did you mean something different?
