Workshop by Tom Cordemans - IPD WEEK - May 2021

During the IPD Week on 5 May 2021 Tom Cordemans will be demonstrating best practices to teach about network security. 

Tom says: "Learning protocols can be hard and sometimes boring. By using the hacker's perspective you can tackle the learning process in a different way. Let's find out. We'll use DHCPv4 as an example." 

We encourage all instructors to take part in Tom's workshop. Tom is an instructor in higher education both in Bruges and Brussels. Moreover, Tom is an active advisor for BiASC. 

Diving into networking protocols by using the hacker’s perspective

Where does Cisco CLI originate from?

Network Collective/ Podcasts/ Episodes

Terry Slattery and Rob Widmer played a significant role in the creation of the Cisco CLI, which has been the industry standard for networking CLIs ever since. In this History of Networking episode we talk to Terry and Rob about the history of how the Cisco CLI came to be and get the story on how the decisions were made that made the CLI what it is today.

Episode 48 – BGP peering in the real world

An excellent podcast on BGP peering. Covers various peering options like settlement and settlement-free peering, concepts like DFZ (default free zone), hot potato and cold potato routing and some of the differences between how an ISP or CDN (Content Delivery Network) peers.

Getting to know DNS security

More than 91% of malware uses DNS to gain command and control, exfiltrate data, or redirect web traffic.

Watch this webinar session to learn how DNS-layer security can help you block threats before they can reach your network or endpoints.

Wireshark captures

For those who like to use Wireshark captures in classes, there is a very good capture repository at:  http://packetlife.net/captures/

Students can easily view capture files on the browser (via Cloudshark) without having to install Wireshark. It is very fast and there are many captures about most of the CCNA & CCNP subjects. Also it's a good choice for those using a lab with polices not allowing Wireshark installation.

What you need to know to teach IPv6 in CCNA2

Presentation by: Rick Graziani, Cabrillo College, 30 OCT 2013

This presentation introduces the IPv6 topics that students will experience in CCNA 2 and what the instructor should know to best teach IPv6. It will help you understand and teach, IPv6 static routes, EIGRP for IPv6 and OSPF for IPv6.

ICC Belgium: IPv6 a Must for Enterprises

The World IPv6 Launch Day on Wednesday 6 June 2012 represented a historic milestone in the development of the Internet. The new Internet Protocol version 6 has gradually to replace the Internet Protocol version 4, which is almost depleted, in order to connect the growing number of devices (PCs, tablets, smart phones, household apparatus, …) and people in emerging countries like China and India to the Internet.

To emphasize the importance of the migration to IPv6 in a joint effort ICC Belgium, BELTUG, Agoria and SFP Economy organized on 12 June 2012 a well attended and successful conference to sensibilize companies to start developing a roadmap to prepare this migration in order not to lose out of competition.

Basic IPv6 Packet Tracer Exercise - no routing

(Click image to enlarge)

Here is a basic IPv6 netwerk plan (with subnets) using manual IPv6 configuration:

• two routers
• two switches
• one server
• two laptops

As this is a basic exercise, no routing has been configured

Tasks

1. Build this network (Download solution: IPv6Basic)
2. Ping the devices
3. Add OSPFv3 Routing
4. Add DHCP for manual configuration of the laptops

IPv6 Routing

The Technical Marketing team from Cisco Networking Academy delivered a series of webinars to provide supplementary training on the topics introduced in the new ICND1 certification covered in the CCNA Routing & Switching courses.

Below are two presentations about IPv6 Routing

• IPv6 Routing Concepts in CCNA R&S
• IPv6 Host Routing Table
• IPv6 Routing Table
• Connected Routes
• Local Routes
• Static Routing
• Default Route

IPv6 Address Prefix Reserved for Documentation - RFC 3849

In the new course materials in examples and exercises regarding IPv6 the network prefix 2001:DB8::/32 is used.

"To reduce the likelihood of conflict and confusion when relating documented examples to deployed systems, an IPv6 unicast address prefix is reserved for use in examples in RFCs, books, documentation, and the like. Since site-local and link-local unicast addresses have special meaning in IPv6, these addresses cannot be used in many example situations. The document describes the use of the IPv6 address prefix 2001:DB8::/32 as a reserved prefix for use in documentation."
