Safe Peering with Prefix Filtering and Route Policies.

Course Overview

Synopsis

This session explains how networks ensure safe and reliable peering using prefix filtering and route policies. It highlights how incorrect routing announcements can cause route leaks, hijacks, or traffic misdirection, and how filtering mechanisms help protect internet routing. Participants will also learn how operators validate prefixes and maintain stable BGP peering at Internet Exchanges for secure and efficient traffic exchange.

Target Audience

Network engineers.

Pre-requisites

Participants should have a basic understanding of networking concepts such as IP addressing, sub netting, and routing fundamentals. Familiarity with BGP, Autonomous Systems (AS), and basic Internet routing will help learners better understand how prefix filtering and route policies work in real network environments.

IPv4 ARP and IPv6 ND

Course Overview

Synopsis

This session introduces the fundamentals of Address Resolution Protocol (ARP) in IPv4 and Neighbor Discovery in IPv6, explaining how devices resolve IP addresses to link-layer addresses for communication within a network. Learners will gain an understanding of the key differences between ARP and Neighbor Discovery and why IPv6 uses a more efficient and scalable approach, with practical relevance to modern networking environments.

Target Audience

Network engineers.

Pre-requisites

Participants are expected to have a foundational understanding of computer networking concepts, including familiarity with the OSI or TCP/IP models, basic IPv4 and IPv6 addressing, and general LAN communication principles. Knowledge of Ethernet, routing, and switching concepts will help learners grasp the topic more effectively, though it is not mandatory, making the session accessible to students and early-career networking professionals seeking to strengthen their understanding of IP networking fundamentals.

ICMP – Internet Control Message Protocol

Course Overview

Synopsis
The Internet Control Message Protocol (ICMP) is a core protocol used by network devices, like routers and hosts, to send error messages and operational information indicating success or failure when communicating with another IP address. This session will explore the structure, types, and real-world applications of ICMP, including how it’s used in diagnostics (e.g., ping and traceroute), how ICMP helps maintain network health, and how it’s handled in modern network security scenarios.
Target Audience

Network engineers.

Pre-requisites

To make the most of this session, participants should have a basic understanding of computer networking concepts, particularly how IP addressing and routing work within a network. Familiarity with the OSI model—especially the network layer (Layer 3)—will help in grasping how ICMP interacts with other protocols. A general awareness of common protocols like IP, TCP, and UDP is recommended. Additionally, prior exposure to network diagnostic tools such as ping and traceroute will provide useful context, though it’s not mandatory.

VLANS & Q-in-Q

Course Overview

Synopsis

VLANs & Q-in-Q

VLANs (Virtual LANs) allow the creation of multiple logical networks over a single physical network, improving security, traffic isolation, and management. QinQ (VLAN stacking) builds on this by encapsulating one VLAN inside another, enabling service providers to carry multiple VLANs over a single connection. Together, they provide scalable, secure Layer 2 networking for enterprises and ISPs.

Target Audience

Network engineers.

Pre-requisites

Participants should have a basic understanding of networking concepts like IP addressing, MAC addresses, and the OSI model. Some familiarity with switch configurations or general network setup is helpful but not required. This session is designed to be accessible for network engineers, data center technicians, and IT enthusiasts alike.

BGP Tools and RPKI

Course Overview

Synopsis

BGP Traffic Engineering

BGP peering tools and RPKI are vital for secure and efficient network operations. Peering tools help monitor, manage, and optimise BGP sessions, ensuring balanced traffic and improved performance. RPKI enhances security by cryptographically validating routing announcements, preventing hijacks and misconfigurations. Together, they enable network operators to achieve reliability, security, and cost-efficiency, complementing modern BGP traffic engineering practices for seamless and optimised data routing.

Target Audience

Network engineers.

Pre-requisites

Participants should have a basic understanding of BGP fundamentals, such as neighbor relationships and attributes. Familiarity with routing protocols like OSPF or EIGRP and experience in configuring BGP in simple setups is recommended. Knowledge of route filtering and basic policies (prefix lists, route maps) will also be helpful for this session.
