Not that the problem doesn't exist, but ...

Sprint does not have a router (or any presence whatsoever) at PAIX. If
anyone at PAIX peers with Sprint from a router located at PAIX, they
must be buying a circuit to a Sprint POP to do it. Since Sprint has no
presence at PAIX, what do you mean by "affects many of the Sprint Net
peers in PAIX?"

Do you have a traceroute to support your assertion that the @Home
router in question is located at PAIX? (I don't know whether it is or
no, but none of the traceroutes into @Home that I do from my PAIX
routers show an @Home router numbered in 172.16.6 as a next hop.)

If there is a problem such as you describe, it's not affecting the
two PAIX routers I have that peer with @Home.
