Can core switches be used for routing
These data switches are responsible for routing and data switching at the core layer of the network. For enterprise network architects and senior infrastructure engineers, determining where Layer 3 routing logic should reside—on the core switch or the Next-Generation Firewall (NGFW)—is a foundational design decision. A misstep here can either cripple network performance with unnecessary. In my research I'm getting mixed suggestions - Some say that core switches are for routing, when others say that core switches have to be as fast as possible and have minimal tasks dedicated to them. I would appreciate any kind of help, and sorry for stupid questions. Engineered to aggregate massive volumes of data from distribution switches, it provides ultra-low latency and maximum throughput to ensure uninterrupted routing and packet. A Core Switch is a critical device that operates in the backbone portion of a network, primarily used for high-speed data switching.
