As output show that our DHCP is working for PC’s, and they have been getting there IP Addresses after DORA Process.
DORA Process is, D(Discover), O(Offer), R(Request), A(Acknowledge) which is conversation model between DHCP client and server for IP assignment.
In this Artice we will write about how to configure a DHCP, DNS and Web Server and for this configuration we will use Layer-3 and Layer-2 switches. DHCP Server Configuration in Layer-3 Switch! A DHCP Server is a network server that automatically provides and assigns IP addresses, default gateways and other network parameters to client devices. It relies on the standard protocol known as Dynamic Host Configuration Protocol or DHCP to respond to broadcast queries by clients. As network design above show that we have connected hosts ( PC's) to Layer-2 switches and so we are not going to assign manual IPs to these hosts, but we will configure DHCP Server for these hosts to get there IP's. In this article we will create VLANS and made there IP pools for DHCP configuration and these VLANS are 10,20 and 30. As commands below show that how we three VLANS 10,20 and 30 are created, and their name a...
Figure 1: Web Server for SecurityWithBlue.com I have a fictional website which I have to host on server and then access the website through server IP . Figure 2: Manual IP Assignment to Server First, we will assign manual IP to server shown above where our website is hosted and then we will go to services and their HTTP and HTTPS are by default ON . ...
Network Design for Layer 3 inter-VLAN communication. what is gateway? A gateway is a device or a software that connects two or more networks and allows data to flow between them. It can also perform functions such as protocol translation, data conversion, security filtering, or routing. I have three layer 2 switches where different networks are installed. I have to configure a layer 3 switch for inter-VLAN communication. First thing first, I will create three VLANs which I will assign IP Addresses to them which will act as default gateway for hosts connected to layer 2 switch. To create VLANs we will use the command VLAN which is built in command for VLAN creation in switch. There i...
