Aperçu du cours

Context:

In today’s global business environment, organizations operate across multiple geographical locations, necessitating a robust network infrastructure that ensures secure, reliable, and seamless communication between sites. This laboratory exercise simulates a real-world scenario where you, as a network engineer, are tasked with designing and implementing a network that supports an organization with headquarters and multiple branch offices.

Problem Statement: The company aims to enhance its network infrastructure to improve connectivity, security, and manageability across three key sites: the headquarters and two branch offices. The network must support various applications and services, including secure internet access and inter-site communications.

Objective: Your task is to configure a network that not only meets the operational requirements but also incorporates advanced routing protocols and security measures to protect against potential cyber threats.

Technologies and Protocols:

• Cisco & MikroTik: Configuration of networking equipment for traffic management, tunnels, and security.
• PfSense: Implementation of a firewall and gateway functions for branches.
• DHCP: Setting up DHCP servers on Cisco for dynamic IP address management.
• ACLs (Access Control Lists): Securing networks by controlling incoming and outgoing traffic through defined rules.
• GRE Tunnel & IPSec: Establishing secure tunnels between different sites.
• NAT (Network Address Translation): Configuring NAT to enable secure external communication.

Routing and Network Protocols:

• Static Routes: Setting up static routes for direct and controlled communication.
• OSPF (Open Shortest Path First) Multi-Area: Using OSPF for efficient route management in an extensive network environment.
• EIGRP (Enhanced Interior Gateway Routing Protocol): Implementing EIGRP to optimize routing performance in Cisco networks.
• BGP (Border Gateway Protocol): Configuring BGP for managing route exchanges between different autonomous systems.

Prerequisites:

• Basic to intermediate knowledge of network configuration.
• Familiarity with Cisco IOS and MikroTik RouterOS.
• Understanding of IP addressing, subnetting, and network protocols.
• Access to network simulation tools like Cisco Packet Tracer or GNS3 for practical implementation.

Environment Setup: Participants will need the following setup to perform the lab:

• Network simulation software (Cisco Packet Tracer or GNS3).
• Access to Cisco routers and MikroTik routers (virtual or physical).
• PfSense software for firewall configurations.
