That's an unrealistic (exaggerated) end result if this case becomes
precedent. Among networks that filter incoming BGP routes, AFAIK, it's
common policy to ignore >/24 prefixes. Announcing /32 routes into
BGP would not give anywhere near the global reachability as doing the same
with /24 or shorter prefixes.
If the [ex-]customer is and remains multihomed (pretty likely if they got
PI space), this doesn't even change the size of the global routing table.
I assume we have their route now through NAC and some other provider. In
a few weeks, we'll still see their route through the other provider and
perhaps a new other provider.
I still don't agree with what they've done. If someone figures out the IP
block in question let me know. I suspect Alex can't post it without being
in violation of the TRO since he knows what we'll do with it.
