Abstract: Need of global networking is increasing day by day and is as a primary need. This paper state the issues related to Intermediate System to Intermediate System (IS-IS) routing protocol, currently that supports routing of Internet Protocol version 4 (IPv4) and 6 (IPv6) and study both the strong and weak points of IS-IS routing protocol. This paper illustrate the working of IS-IS and issues (Routing, addressing, packet format, area and domain) related to IS-IS because it will be helpful for understanding the key things related to IS-IS. There are various intra routing protocols among which OSPF is very popular but IS-IS is more flexible than OSPF. This paper also gives some prospective ideas that why we can’t ignore IS-IS. This paper also describe the issues that are related to different resources utilization in IS-IS and in similar link state routing protocol such as OSPF and describe the proper difference why and in which situations IS-IS is better than OSPF.
Keywords: (IPv4), IS-IS, OSPF.
