Right, PTP and loopback prefixes are distributed with OSPF (and possibly
management subnets for radios) and "access" network prefixes (customer-facing)
are distributed via iBGP.

Regardless of the culprit, the cause of this will be a misconfiguration of some
kind and likely not even with OSPF. OSPF is not weird, nor does it behave
badly; it merely reacts to conditions based on a predetermined set of
algorithms which are very well documented and implemented, especially
I've said it before, and been argued with... this is one of many reasons
why you use iBGP to distribute {customer, dynamic pool, server subnets,
anything} routes, and use OSPF *only* to distribute router loopback
addresses. All your weird OSPF problems will go away. My apologies if
I'm
IP assignments that
you wanted to follow the CPE around your network, that would be different. But
you could still do that with a non-pool address.

Is it possible another router somewhere is announcing x.x.x.208/28

the route table, but what about other prefix lengths?

Alright, this problem has raised it head again on my network since I started
to renumber some PPPoE pools.
Customer gets a new IP address via PPPoE x.x.x.208/32 (from x.x.x.192/27
pool). Customer can't surf and I can't ping them from my office:
