WebRouters – Layer 3 A router has more “intelligence” than a switch because it can make decisions based on layer 3 addresses in packet headers (usually IPv4 or IPv6 addresses). Routers are used to determine how to route packets received on one interface to a network on another interface, to move the packets toward their final destination. WebLayer 3 switches make decisions based on the port-level Internet Protocol (IP) addresses, whereas routers make decisions based on a map of the Layer 3 network (maintained in a routing table).
