  Actually 7600 with SRA does not have the Load Info mechanism to update
prefixes which are pointing to label or interface.
  You need to push the  virtual Label so that the update of the prefixes are
fast enought for FRR, because of this packet is recirculated   back to PFC,
this may end up with some cef bugs.
