Realization of Virtual-Link on a Network
Anil Umesh · IJARCCE · 2018
A network is group of computers and other devices running on suitable protocols enabling data and multimedia communication.Multimedia includes image, audio, video and text.Router is a part of the network and is responsible for forwarding the packets.A routing protocol specifies how routers communicate with each other.Open Shortest Path First (OSPF) is a dynamic routing protocol and uses Dijkstra shortest path first algorithm to determine the shortest path.OSPF employs a hierarchical network design using areas.Area 0 is the backbone area.All other areas that is area n, where n=1,2,3….are (must be) directly connected to the backbone.But in several cases the nonbackbone area cannot be directly connected to area 0. In this paper we present to you the configuration of virtual-links to logically connect separated areas to area 0.
