  According to RFC4456 Section 9 the OriginatorID has to be used instead
  of the Originator/RouterID when breaking ties, if an OriginatorID set
  by a route reflector is present.

  In addition a shorter ClusterList (none -> lenght 0) wins the best path
  election right after the aforementioned check.
