What is a major advantage of OSPF over EIGRP?

One major advantage of OSPF (Open Shortest Path First) over EIGRP (Enhanced Interior Gateway Routing Protocol) is that OSPF supports multiple area configurations. This capability allows OSPF to scale to larger networks by dividing them into smaller, more manageable areas, while still maintaining a hierarchical structure. Each area can function independently and reduces the size of the routing tables that each router must maintain. This segmentation leads to more efficient routing, as it limits the scope of routing updates and fosters improved resource utilization.

In contrast, EIGRP operates within a single autonomous system without the same area division, which can lead to larger routing tables and potentially slower network performance as the size of the network increases. OSPF's area-based approach also helps in reducing unnecessary traffic and improving convergence times in larger networks.
