Does he has something particular in mind ? Like only routing
a few AS to you because you have good connectivity (peering?)
to them ?
If this is the case, go with filter-list and only annonce him
routers with a particular AS in the path.
If not, then just tell him this is useless. Only annoncing
400 routes from the global Internet tables sounds kind of funny
to me.
You can reduce the full table by dropping "lower-than" some
subnet mask length prefix (like all the /24) but I doubt you
will go down to only 400 routes.
