...again, I'm confused.
BGP updates from where to where? From how I understand the OP's original
question, there is no BGP.
Hence, if one of the providers is statically routing the prefix to an
interface or un-numbered as opposed to an IP address, then blackholing
can occur if IP reachability is broken, but the link-layer is not. Is
this not correct?
