You should have iACLs and GTSM enabled, as noted previously.

Ideally, the link should come from an unadvertised range, or a range 
which is sunk to null0 at the edge, as Job indicated.

If the link is numbered from a range assigned to your peer, they should 
have iACLs in place to prevent that range being packeted.

If the link is numbered from your own range, you should ask your peer to 
add that range to their iACLs, as well.
