Key Differences Between Layer 2 and Layer 3 Switches in Networking

Layer 2 and Layer 3 switches are crucial components in a network infrastructure. Understanding the differences between them is essential for efficient network management.

Focus Keyword: Layer 2 vs Layer 3 switches

Layer 2 Switches:

• Operate at the Data Link layer of the OSI model
• Uses MAC addresses for packet forwarding
• Provide basic network connectivity through MAC address table
• Offer VLAN segmentation
• Do not perform routing functions

Layer 3 Switches:

• Operate at the Network layer of the OSI model
• Uses IP addresses for packet forwarding
• Can perform routing functions
• Support routing protocols like OSPF and BGP
• Offer more advanced routing and traffic management capabilities

Overall, while Layer 2 switches are more basic and operate at the Data Link layer using MAC addresses, Layer 3 switches add routing functionalities by operating at the Network layer and utilizing IP addresses for packet forwarding.
