You might have run into the not-so-graceful transition from the old "nlri"
BGP syntax & the new "address-family" BGP syntax.  The following might be
pertinent:

  http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120st/120st14/confmbgp.htm

Watch out for "match nlri" in route-maps in that context.

On the other hand, it might not have anything to do with that.  ;^)
