Abstract
The present disclosure relates to a method for hierarchically managing routing information in a domain router for routing domains on a network. The method includes: storing and managing a domain state advertisement message received from a neighboring domain router in a storage unit in a certain database format, generating at least one management target domain area according to the domain state advertisement message, and generating management information including a spanning tree including routing topology information and a routing table for each of the management target domain area to maintain in the storage unit; and reconfiguring the spanning tree according to a change of the database or a given cycle and updating the routing table to store and manage in the storage unit.
