Layer 2 vs layer 3

While network segmentation is traditionally enforced at Layer 2 (VLANs) or Layer 3 (subnets), the concepts of segmentation—the containment of certain network activities—can be implemented at essentially any layer of the OSI model, often to great effect. For example, by limiting sessions and applications at OSI Layers 4–7 instead of Layers 2–3, it …

OSI Layer 3 - Network Layer. In the seven-layer OSI model of computer networking, the network layer is layer 3. The network layer is responsible for packet forwarding including routing through intermediate routers, since it knows the address of neighboring network nodes, and it also manages quality of service (QoS), and recognizes and forwards ...Layer 3 Dynamic Routing Protocols.

The IP, vlan tag etc. are directly on the interface. In the secound variant I would configure the trunk interface as layer 2 which I assign a vlan interface. Simplified the following network scheme:Step 2. Router (config-if)# no ip address. Ensures that there is no IP address assigned to the LAN port. Step 3. Router (config-if)# channel-protocol ( lacp | pagp } (Optional) On the selected LAN port, restricts the channel-group command to the EtherChannel protocol configured with the channel-protocol command.

LAYER 1 - The physical layer in the wired world consist of connectors, cables, fiber, and gbics. This is also the layer where data gets transmitted / received into bits, 0's and 1's using complex coding and modulations. LAYER 2 - The data layer is where upper layer information (Layers 3-7) is encapsulated into a frame.

The most significant protocol at layer 3 (also called the network layer) is the Internet Protocol, or IP. IP is the standard for routing packets across interconnected networks--hence, the name internet. It is an encapsulating protocol similar to the way Ethernet is an encapsulating protocol. If we view the original check as a unit of data needed to be sent, …The network layer can have at least three sub- layers: 1) Sub-network access that considers protocols that deal with the interface to networks, such as X.25; 2) Sub-network dependent convergence, used when it is necessary to bring the level of a transit network up to the level of networks on either side; and 3) Sub-network independent ...And to best understand the difference between Layer 2 switches and Layer 3 switches, you also need to know the difference between Layer 2 and Layer 3 in the OSI networking model.
