You should be advertising /32's and /128's. From the hypervisor to the TOR, then the TOR aggregates if possible and advertises to a spine.
Yeah, that's what I meant. I thought that was clear from "aggregate an entire rack to a single prefix" but perhaps not.
When I said don't advertise /32s I meant "globally" and as a general rule (I didn't realize what I said would be taken so literally). There can be exceptions, of course, such as in the live-migration case you mentioned.
