Configuration of OSPF, DHCP, and VLANs in Data and Computer Networking

This document presents a solution to a practical assignment focused on data and computer networking. The project involves configuring a network using OSPF for dynamic routing and distributing a default route. It also covers configuring RSTP, port security, EtherChannel, DHCP, VLANs, and trunking, as well as routing between VLANs. The solution includes initial switch configuration, securing switch ports, and creating SVIs. Specific steps detail the planning and implementation of OSPF router configuration, including addressing, interface configuration, inter-VLAN setup, default routing, and OSPFv2 multiarea customization. Furthermore, it addresses switching and DHCP configuration, covering VLAN creation, port assignment, SVIs configuration, EtherChannel and trunking, Rapid PVST+, switch security, and DHCP server setup for hosts. The configuration is completed by manually setting up addressing on each workstation, ensuring full network communication. Desklib offers many resources for students looking for solved assignments and past papers.

OSPF Router Configuration
Step 1: Plan the Addressing
Step 2: Building 1 Configuration
Bldg-1 will be the router host name and must be used exactly as it is
Preventing the router from trying to resolve entries of IP address via command line
Configuring encrypted password on the router to prevent unauthorized access

Data and Computer Networking 4
Securing remote access line and console of the router
Disallowing system notifications from affecting console output
Setting up pop up message banner
Password encryption

Step 6: OSPF Routing Configuration
1.1.1.0 or/32 Wild Card Mask Calculation
Since we have 30 bits, only 2 will remain
0.0.0.3 will now be our wild card from above calculations
For a /24 network bit pattern will look like the screenshot below

Data and Computer Networking 9
Thus, 0.0.0.255 will be /24 wildcard
The information above will now be used to set up several networks on every router
Disallowing LANs from receiving routing updates
OSPFv2 (Main) multiarea configuration for default route distribution to other routers

Step 7: OSPFv2 Multiarea Customization
Setting the bandwidth of all serial interfaces to 128kb/s
OSPF Router IDs Configuration
Building 1: 1.1.1.1
Main: 2.2.2.2
Building 2: 3.3.3.3
