ABSTRACT:
A communication device includes a static routing table, a dynamic routing table and a judging unit. The judging unit, if no failure occur in a static route, selects the static route based on routing information given from the static routing table as a route to which a packet should be forwarded. The judging unit, if the failure occurs in the static route, selects a dynamic route based on routing information given from the dynamic routing table as a route to which the packet should be forwarded.
