Abstract:The routing protocol is one of the important members of the TCP/IP protocol family, which contains the internal and external network protocol. The common network protocol in college is static routing and OSPF routing. This paper analyzes and summarizes the related theories of OSPF protocol and static routing, and initiatively closes down the network services by introducing the origin of the static black hole road according to the demand of campus network security management. Based on this, the paper introduces the black hole routing network architecture into the security management of campus network, and gives the network architecture of the core and the specific configuration process. With the aid of black hole, the routing can quickly close down the accident point to prevent more hazards, and reduces the negative impact on the entire campus network. Eventually, through the network the validity of the black hole routing configuration is tested.
