LLDP (Link Layer Discovery Protocol) is a protocol that runs on the Layer 2 layer of OSI, designed to discover network devices such as switches and routers in local networks. In addition, this protocol, designed as an alternative to CDP, is defined in the IEEE 802.1AB document and performs sending, receiving, and managing with the agent providing communication between devices.
You can gain experience by designing network topologies on GNS3 or use IOS images of real Cisco devices. By adding IOU devices to your network project, you can use the Cisco Layer 2 Switch and Layer 3 Switch.
In our previous article, we looked at how to configure DHCP Server on Cisco Routers. In this article, we will examine how automatic IP addresses are assigned to clients from DHCP Server on a different network.
Switch network devices provide data communication between the computer or all devices connected to the network. How do Switches work and learn the MAC addresses of devices on the network?
