Which routing protocol is considered a link-state protocol supported on Aruba AOS-CX switches?

The correct answer is OSPFv2, which stands for Open Shortest Path First version 2. This protocol is a widely recognized link-state routing protocol that operates using a method of exchanging information about the network topology among routers. In link-state protocols, routers share information about the state and cost of their links to form a complete and consistent view of the network topology.

OSPFv2 works by exchanging link-state advertisements (LSAs) between routers, enabling them to build a link-state database. This database is then used to create a routing table based on the most efficient paths for forwarding packets. This approach allows OSPF to provide faster convergence and more scalable network designs compared to distance-vector protocols.

The relevance of OSPFv2 in the context of Aruba AOS-CX switches is significant, as these switches support advanced routing features that can benefit from OSPF's capabilities in dynamic environments where changes in the network are frequent. This makes OSPFv2 a preferred choice for network professionals looking to implement efficient routing solutions on modern switching platforms like those from Aruba.
