An internal router will add the cost to reach a ... Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS). OSPF gathers link state information from available routers and constructs a topology map of the network. The topology is presented as a routing table to the Internet Layer for routing packets by t… WebOSPF works with the concepts of areas and by default you will always have a single area, normally. this is area 0 or also called the backbone area. fYou can have multiple areas however as in the picture above, we have area 1,2 and 3.
