Can an aggregation switch be used as a gateway

In this example, aggregation switches set up stacks that function as gateways for wired and wireless users on the entire network and are responsible for routing and forwarding of user services. By bundling multiple network connections into a single high-bandwidth link, aggregation switches help. An Aggregation or "Top-of-Rack" switch is designed to connect everything in a rack at high speeds, then have an even bigger pipe out to the rest of the network. The Pro Aggregation does this with it's SFP28 25Gbps ports. It helps in managing higher traffic loads between switches.
