WebMar 2, 2024 · 3. OSPF can work efficiently without area 0 when there is only one area. When there is a need for more areas, OSPF traffic should pass through the backbone area (area 0) to avoid the routing loop. OSPF runs Link State protocol inside the area, However, it uses Distance Vector protocol to advertise the routes between areas. WebOSPF uses areas so you need to specify the area: area 0 In our example we have configured single area OSPF. All routers belong to area 0. After typing in my network command you’ll …

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… WebIt is a method to isolate areas from each other, summarize routes and contain issues to a smaller area in your network. OSPF can summarize only at one level (ABRs), EIGRP can summarize at unlimited levels, if the IP design supports such a structure. This does not mean that OSPF is less attractive.
