Research on Types of LSA in OSPF Multiarea Network Based on ENSP

OSPF is a widely used link state routing protocol in Internet. In large enterprises, areas are used in OSPF to design networks. In different OSPF areas, routers generate different LSAS according to their respective roles. Various LSAS work together to generate a routing table for each router. This paper will analyze and research the types of LSA in OSPF multiarea network.
