| With the promotion and popularization of computer network, the networks occupy an increasingly important position in people’s lives. Stable and efficient routing protocol is an important factor in the performance guarantee credible router, so the study of the impact of network routing protocols situation has far-reaching significance. To adding new features to the existing platforms is essential and urgent. Each network equipment manufacturers also attaches great importance to the development and research work related to routing protocols.This paper deeply concerned about the development process of the project-specific processes, problems and expansion based on the well-known manufacturers:: Hangzhou H3C Technologies Co.Ltd. R&D projects for commercial development on the characteristics of the common OSPF protocol elaborate and research.In this paper, with an in-depth understanding on the OSPF protocol, and on the basis of the relevant technical documentation to RFC5340standard, using agile development methodologies, design and implementation support for OSPFv3NSSA area function features. The main work of this paper include:adding the support for the NSSA command line, adding the support for FA address, increasing the role of supporting the NSSA Translator election, process of NSSA area route calculation. In order to achieving the completion of the NSSA characteristics based on the original system platform, and complete ana routing table normally. Finally, the basic functions of verification and performance testing on the H3C router machines. |
