This cisco network diagram example was drawn on the base of the figure illustrating the post cisco lab 1. This layer is embedded as software in your computer s network interface card nic.

Layer 3 networks are built to run on on layer. The third layer of osi model is the network layer. A router works with ip addresses at layer 3 of the model. I usually start with a layer 3 network diagram to show the routing and ip subnets.

Network partition is used to group networking components together while host partition is used to uniquely identity a system on a network. You can edit this network diagram using creately diagramming tool and include in your report presentation website. From 1st customer project assign r1 dmvpn and r2 dwvpn as dmvpn hub and r3 dmvpn and r4 dmvpn as. The data link layer provides the functional and procedural means to transfer data between network entities and might provide the means to detect and possibly correct errors.

This layer takes data segment from transport layer and adds logical address to it. Network partition and host partition. After that comes a layer 1 diagram showing physical layouts of the devices. These comparisons are based on the original seven layer protocol model as defined in iso 7498 rather than refinements in the internal organization of the network layer.

The data link layer or layer 2 is the second layer of the seven layer osi model of computer networking this layer is the protocol layer that transfers data between nodes on a network segment across the physical layer. A logical address has two components. A network diagram showing layer 2. Then i make a layer 2 diagram showing the switch connections trunks and lacp channels.

It s also a good idea to make a separate diagram for each network protocol layer. Layer 2 concepts layer 2 protocols basically control access to a shared medium copper fiber electro magnetic waves ethernet is the de facto wired standard today reasons.

Network design from the requirement from the blog thai cisco club. The link layer corresponds to the osi data link layer and may include similar functions as the physical layer as well as some protocols of the osi s network layer. However a properly configured layer 3 network with the correct knowledge and hardware can have infinite growth.
