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. 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.
