IS-IS is a link-state interior gateway routing protocol. Like OSPF, IS-IS runs the Dijkstra shortest-path first (SPF) algorithm to create a database of the network’s topology and, from that database, to determine the best (that is, shortest) path to a destination. IS-IS : Intermediate System to Intermediate System IS-IS as Intermediate System to Intermediate System Unlike OSPF, which was developed and standardized by the Internet Engineering Task Force (IETF), IS-IS is an ANSI ISO protocol and was originally based on the Digital Equipment Corporation DECNET Phase V Network Technology. IS-IS uses a slightly different terminology than OSPF for naming its protocol packets. The packets that IS-IS routers send to each other describing the network topology are called link-state protocol data units (link-state PDUs, or LSPs). In addition to describing the network topology that the router knows about, the link-state PDUs include IP routes, checksums, and other information. Similar to...

What is a router? A router is a networking device that forwards data packets between computer networks. A router is a hardware device that allows the affiliation with each computers in the network. The router is a device that operates in layer three of OSI model (Network Layer). A router uses a routing protocol, which is helpful with finding out the fastest and suitable route to send Data.   The router has multiple more and less complex uses. In its most common use, a router allows several computers to take advantage of the same Internet connection in a small home or office. In this sense, the router operates as a receiver of the network connection to take charge of distributing it to all the equipment connected to it. Thus, a network or Internet is connected with another one of local area. Nowadays, it is easy to obtain a router in a economic way from different brands. There are also those routers that use open source software and therefore allow a greater ec...
