Abstract: This paper analyses the advantages and limitations of the OSPF which is the dynamic routing protocol, also introduces the NSSA because the Stub zone can not channel into external without OSPF routing, NSSA can remedy this disadvantages. Meanwhile, through a sample, it introduces the actual application of NSSA on the Cisco router and presents the importance of NSSA.
