Figure 1: Network Diagram for Project In this article we have been configuring Microsoft Windows DHCP for inter-VLAN network segments involves setting up separate DHCP scopes for each VLAN and enabling IP helpers on the Layer-3 Switch to relay DHCP requests from clients on different VLANs to the DHCP server.   What is DHCP? DHCP (Dynamic Host Configuration Protocol) is a protocol that provides quick, automatic, and central management for the distribution of IP addresses within a network. It’s also used to configure the subnet mask, default gateway, and DNS server information on the device.     As shown in figure we will first of all make three VLAN’s 10,20 and 30 having name VLAN10, VLAN20 and VLAN30 respectively.                            Figure 2: VLAN Creation in Layer-3 Switch   Now we will give IP address to VLANS interfaces we have created in Layer-3 switch as shown in figure 2 to act ...

  In this configuration article we will see how different networks can communicate using router, Router definition is given below. A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses and allowing multiple devices to use the same Internet connection. Router which we are using in packet tracer file is 2911 which has two interfaces which mean we can two different networks, so we will configure interfaces for each network and also to get the functionality of routing (communication between networks) from router. After entering in global configuration, we will select the interface GigabitEthernet 0/0, which we want to configure for left network, Up the interface as in router by default interfaces are down as given below: Figure 1: Router Interface getting up. After this we will assign the probably first IP of that netw...
