We formally prove the range limit of topology observed by a BGP monitor based on the valley free model.By comparing with the actual BGP data
we found that for more than 90% of monitors
the observed P-P links are less than 30% of its range limit.By analyzing the relationships between the characteristics of observed ASes and the completeness of observed topology for those ASes
we found that the completeness of the topology is impacted by the distance to the BGP monitor
