Abstract: Disclosed is a method for checking for errors and problems in routing protocol modules through hello packet transmission in a distributed router that is mounted with a network processor, a system processor, a routing protocol module, and a switch module including at least two input/output processors which can be operated together with independent routers, a system processor, and a designate routing protocol module. The method including the steps of: checking hello packet transmission cycle; if the hello packet transmission cycle has expired, transmitting a hello packet to the adjacent routing protocol module; receiving a hello response packet from the adjacent routing module; if the adjacent routing protocol module does not send the hello response packet, concluding that the adjacent routing is malfunctioning; and transmitting information on the malfunctioning adjacent routing protocol module to the designate routing protocol module.
