Welcome to the Layer 3 IPv4 Multi-Day Instructor Led courses!

These courses all focus on IPv4, and Routing, all with detailed hands-on lab experiments to build skills and knowledge.  Several of the courses blend Ethernet and IPv4, which are essential technologies for today's data and computer communications.  

The courses are Instructor Led with either Web Based delivery or on-site delivery available.

We offer some online self paced courses in this area as well.  If you are looking for an online, self paced course on Routing, or IPv4 Addressing, or other similar subjects, click here.

Knowing the fundamentals of the Internet Protocol version 4 (IPv4) and the TCP/IP protocol suite is vital to anyone who is in the networking field today, whether it be Service Provider level or Enterprise level. This insightful and revealing course has been designed to focus on the systems approach, the engineering thinking, behind the world of IP Networking.

Knowing the fundamentals of Ethernet and the Internet Protocol TCP/IP protocol suite is vital to anyone who is in the networking field today, whether it be Service Provider level or Enterprise level. This insightful and revealing course has been designed to focus on the systems approach, the engineering thinking, behind the world of Ethernet and IP Networking.  See the course details here.

Every day, those who work in networking are having to understand the behavior of Transmission Control Protocol (TCP).  Whether it is in IPv4 or IPv6, over 90% of network traffic is carried inside TCP.  TCP is perhaps the most complicated protocol on the Internet.  Plus there are multiple versions of TCP in use!  In this course, through hands on exercises, we study the various algorithms and behaviors of TCP by using Wireshark to study and visualize what happens when TCP works, and when it does not work.  Algorithms lick Slow Start, Selective Acknowledgement, Retransmission, are just a couple of examples.  This insightful and revealing course has been designed to focus on the systems approach, the engineering thinking, behind the world of IP Networking.

This Hands On OSPF course dives into the worlds most popular internal gateway protocol.  The course covers the protocol method and communication process that OSPF uses to form adjacencies, then dissects the shortest path first process.  OSPF uses Areas for scalability, and the course explores these capabilities as well.  Finally the course explores some OSPF features such as High Availability all built on GNS3 hands on labs.

Knowing the fundamentals of the BGP routing protocol is vital to anyone who is in the networking field today, whether it be Service Provider level or Enterprise level. This insightful and revealing course has been designed to focus on the systems approach, the engineering thinking, behind the world of BGP Routing.

This advanced  L3 routing course combines individual topics such as OSPF, BGP, Multicast, VXLAN, ECMP, and other Layer 3 topics into a single two-day hands on lab class.  These issues are ripe for the Data Center network engineers and product developers as these large, complex, multi-tier networks have needed to grow laterally blowing out of the Spanning Tree and VLAN tag capabilities.
