How it works? Frame Relay uses the special purpose hardware components including frame routers, bridges & switches which are used toRead More
What Are OSPF Areas and Virtual Links?
Introduction OSPF is an open standard link state protocol which uses Dijkstra algorithm. It is a classless routing protocol, supports VSLM and discontinuous networks by sending subnet mask information as part of a route advertisement. Its administrative distance value is 110. Its hop count is unlimited. It supports only equal cost load balancing. It providesRead More
