The Research on the OSPF Security Optimizing of Campus Network

With the rapid development and extensive application of network information technology in the 21st century, computer networks based on OSPF protocol gradually exposed OSPF security problems and the routing tables´ rapid growth issue. At the same time, along with the deepening of China´s education system and universities increasingly expanding, campus network rapidly increase users and have more and more business. Aimed at the OSPF security problems existing in the large campus network, the paper research the OSPF security optimizing design from the accessibility of the non-backbone area route, OSPF external routing propagation control and routing spread control in OSPF area.
