Certain Cisco switches can be configured to function as Layer 3 devices, enabling routing capabilities. The ability to support Layer 3 functionality depends on the specific switch model, with some supporting various routing protocols like RIP and OSPF, while others are purely Layer 2 devices. The command 'ip routing' is used to enable Layer 3 features on compatible switches, allowing for inter-VLAN routing.

Switch Capability for Layer 3

• 00:00:28 Not all Cisco switches support Layer 3 functionality; some are purely Layer 2 devices. The Cisco 2960 is a Layer 2 switch, while the Cisco 3560 supports Layer 3 functionality after enabling IP routing. The command 'ip routing' enables Layer 3 capabilities on compatible switches.

Routing Protocols and Inter-VLAN Routing

• 00:01:26 Layer 3 switches support various routing protocols, including RIP, OSPF, and EIGRP, but the specific protocols supported vary by model. The Cisco 3560 supports multiple routing protocols and inter-VLAN routing, allowing for routing between different VLANs. Layer 3 functionality on a switch allows for routing between different network segments.
