WebMar 26, 2024 · OSPF can consolidate a fragmented OSPF area into one large area. Arranging routers into areas partitions a large autonomous system in order to lighten the load on routers. All routers are in one area called the backbone area (area 0). OSPF multiarea increases the frequency of SPF calculation. 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.
