You have to explain me how you do that. I just looked at my home router
and a single /48 block appears nine times in the config and related info
such as tunnel addresses appears eight more times, so a total of
_seventeen_ occurrences of addresses related to _one_ of my pTLAs, and
again this is my home router with only one subnet, not a production one
with long access-lists, DMZs and other stuff. 

What kind of software is it that can read a config, inventory what needs
to be changed, change it, and not screw the pooch?

Agree!
