Chances are you receive the route to the BGP next-hop(s) via BGP, so
you'll end up in a recursion loop.
Two solutions (in the order of preference):
1) configure an IGP (OSPF, etc.) to provide reachability to the
next-hops
2) Assuming the "neighbor 208.67.xxx.x" is actually the adjacent
router's address on your FastEth1/0, manually change the next-hop on
this router using
neighbor 208.67.xxx.x route-map SET-NH in
route-map SET-NH
set ip next-hop peer-address
Hiding IP addresses in this case makes it difficult to properly
troubleshoot..
