actually, to do it right, both have to advertise the longer prefix --
or more specifically, they have to both make holes in their filters
permitting the multi-homed site to advertise them.
this is what we're doing in our Troy, NY facility -- we have 2
upstreams,
and we have a /24 from one of them, which both of them pass through.
