Abstract
The present invention provides a BGP route evaluation device and method. A message receiving section 101 receives a BGP Update message. A status detecting section 102 detects the active/inactive status of each BGP route on the basis of a pair of prefix and next hop registered in “Announce” and “Withdraw” of the BGP Update message. In a management table 104, the active/inactive status of each BGP route is managed. An update section 103 updates the registration contents of the management table 104 on the basis of the detection result of the active/inactive status. An evaluation section 105 evaluates each BGP route on the basis of the registration contents of the management table 104.
