OSPF Network Design and Implementation

Overview

This project configures OSPF routing between multiple Cisco routers with dual-stack support (IPv4/IPv6) and subnetting. The configuration focuses on OSPF implementation, ensuring optimized routing between various network segments. image

Topology

  • Subnets: IPv4 and IPv6 dual-stack setup for efficient routing.
  • Routers: ISR4321 Routers (Handling OSPF routing between different networks).
  • Switches: 2960-24TT Switches (Handling VLAN segmentation and trunking).
  • Devices: PCs configured with static IP addresses for communication within VLANs.

Objectives:

  • Implement OSPF routing for efficient communication between networks.
  • Use IPv4 and IPv6 subnetting to create structured network addresses.
  • Configure VLANs on switches for better traffic segmentation.
  • Secure the routers and switches with password encryption and SSH access.

Network Details:

Subnet Configuration:

  • Subnet 1: 172.16.10.0/24 for the main network.
  • IPv6 Subnet: 2001:db8:1::/48 addressing for IPv6 network communication.
  • Point-to-Point links between routers:
    • 172.16.10.0/30 (R1-R2 link)
    • 172.16.10.4/30 (R2-R3 link)

Addressing Table:

Refer to the Addressing Table and Objectives for complete IP address assignments, or check the details below:

Device Interface IP Address Subnet Mask/Prefix Description
Router 1 (R1) G0/0/0 172.16.10.33 255.255.255.224 Network to switch S1
S0/1/0 172.16.10.1 255.255.255.252 Link to R2
Router 2 (R2) S0/1/0 172.16.10.2 255.255.255.252 Link to R1
S0/2/0 172.16.10.6 255.255.255.252 Link to R3
Router 3 (R3) S0/2/0 172.16.10.5 255.255.255.252 Link to R2
Switch 1 (S1) VLAN 10 172.16.10.34 255.255.255.224 Management VLAN
Switch 2 (S2) VLAN 10 172.16.10.98 255.255.255.224 Management VLAN

VLAN Table:

VLAN VLAN ID Subnet Description
VLAN 10 10 172.16.10.32/27 Network connected to S1
VLAN 20 20 172.16.10.96/27 Network connected to S2
Management VLAN 100 192.168.100.0/29 Secure management access

Configuration Files

Steps to Implement:

  1. Configure OSPF routing on routers.
  2. Set up VLANs on switches.
  3. Secure devices using SSH, password encryption, and banners.
  4. Assign appropriate IP addresses to interfaces.
  5. Verify connectivity and OSPF routes between devices.
