METHOD FOR SUPPLYING ROUTING INFORMATION IN DISTRIBUTIVE ROUTER

摘要

PURPOSE: A method for supplying routing information in a distributive router is provided to change a route entry of a routing table, and to show the changed route entry when routing information of the routing table is shown, thereby preventing an inner interface port number from being exposed. CONSTITUTION: When a routing information display command is inputted(S110), a switching portion requests a routing processor to transmit routing information of a routing table(S112). When the routing information is received(S114), the switching portion decides whether an inner interface port number is included in an interface field of a route entry of the received routing table(S116). If so, the switching portion performs a net mask process for a next hop address of the route entry, and finds out a network number(S118). The switching portion sequentially performs a net mask process for interface IP addresses(S120), and decides whether an interface IP address has an identical network number with a network number of the next hop address(S122). If so, the switching portion changes an interface field value(S124).
