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. WebMar 1, 2024 · There is only one way to use OSPF without an Area 0, and that is to use OSPF with a single area. If you only have one OSPF area, you can number it any way you like, but …

WebNov 9, 2024 · Basically, OSPF works on the concept of "areas." Most networks simply put all OSPF prefixes under an autonomous system into a single area numbered 0 for backbone, which means that each node has a full view of the topology. This allows each device to determine the best next hop for any particular destination. WebOSPF uses a LSDB (link state database) and fills this with LSAs (link state advertisement). Instead of using 1 LSA packet OSPF has many different types of LSAs and in this lesson I’m going to show all of them to you.
