On a fabric network of a large or midsize campus network, there are 20 edge devices. Which of the following OSPF route orchestration modes should be used in this case?
For mid-to-large campus fabrics (typically those with more than 10-15 edge devices), Huawei recommends Dual-OSPF-area orchestration (C) for the underlay network. In this design, Area 0 is usually established between the Core (Border) and Aggregation nodes, while Area 1 (or other non-zero areas) is used between the Aggregation and Edge nodes. This hierarchy limits the scope of Link State Advertisements (LSAs), preventing a single link flap at the edge from causing a full SPF recalculation across the entire network backbone, thus enhancing stability.
