It did not work for me either. After doing a tiny bit of research, I
concluded it was not supported

<snip>
The BGP Conditional Route Injection feature is supported by all platforms in
Cisco IOS Release 12.2(14)S that support BGP:

  a.. Cisco 7200 series
  b.. Cisco 7400 series
  c.. Cisco 7500 series
