A hierarchical design with OSPF (Open Shortest Path First) enhances network scalability, efficiency, and manageability. By segmenting the network into areas, it reduces the size of routing tables and limits the scope of route advertisements, which minimizes the overhead on routers. This structure also improves convergence times and allows for more effective troubleshooting and maintenance, as changes in one area have a limited impact on the overall network. Additionally, it provides better control over routing policies and improves overall network performance.

Open Shortest Path First (OSPF) is a routing protocol used in Internet Protocol (IP) networks to determine the most efficient path for data to travel across a network. It operates as a link-state routing protocol, enabling routers to share information about the network's topology and calculate the shortest path using Dijkstra's algorithm. OSPF is designed for scalability and can support large and complex networks, allowing for fast convergence and efficient routing updates. Additionally, it supports hierarchical network design through the use of areas, which helps optimize routing efficiency and manage large networks effectively.
OSPF LSA throttling helps the dampening of LSA updates in OSPF during times of network instability.
OSPF is short form of open shortest path first. OSPF is based on linked state routing.

There are actually two OSPF and IS-IS
OSPF stands for open shortest path first. OSPF is an exterior routing protocol. OSPF uses Path vector routing algorithm.
Could be because your routers do not support OSPF.
OSPF is a link-state routing protocol that helps Routers exchange IP routes. OSPF Adjacencies is the established "neighborship" between two OSPF routers in order to make the exchange of routes. In this case, Adjacency means the same as "peering", that the OSPF speakers (routers) are able to "talk" to each other.
The "ip ospf cost" command can be used to manually set the cost of an OSPF-enabled interface. The "bandwidth" command can indirectly affect OSPF metric calculation by adjusting the bandwidth on an interface, which in turn affects the OSPF metric calculation.
