such an advertisement. The same inbound consistency check applies to peers and upstreams/transits.
What do you do when one of your multi-homed customers on your IP space has an outage on their connection to your network? How would your customers then reach that customer?
He explicitly said "single-homed". Of course, multi-homed requires different handling, because you may hear their other home announce them (although again, you probably shouldn't listen to *THAT* announcement either if *your* link to them is up). And I posit that if you don't know if your customer is single or multi-homed, you have *bigger* issues to deal with.
