Provider P allocates a block of address space A to customer, I an ISP.
I allocates a /24, call it B, out of that block to one of their customers, C.
C later leaves ISP I and gets a wire directly from provider P.
I wishes to give C time to renumber.
I would expect the world to see the following announcements.
A - I announcing a shorter prefix, A
B - P announcing a more specific for the /24 allocated to C
Is this not what we all expect?
Why I ask is we have provider P telling I that they should stop announcing A
and instead announce a bunch of prefixes around the /24.
