Definitive IP routing for engineers Training in Germany

An intensive hands on IP routing course leading to LINX Accredited Internet Technician stage 2 focusing on routing in an IP environment. The course concentrates on OSPF and IS-IS but also covers STP and VLANS. Hands on sessions are used to reinforce the theory rather than teach specific manufacturer equipment.

TCP/IP Foundation for engineers

By the end of the course delegates will be able to:

• Calculate subnet numbers in seconds.
• Configure and troubleshoot static routes.
• Explain how OSPF works.
• Build resilient networks with VRRP and OSPF.
• Implement and troubleshoot OSPF, IS-IS and VLANS.
• Evaluate and choose appropriate routing protocols for particular scenarios.

Basic routing

Review of LAIT I routing, reading routing tables.

Setting up a routed network.

Static routes

Why use static routes? Default routes.

Configuring static routes.

First hop redundancy

Default gateways, VRRP/HSRP/GBLP. Load sharing, critical IP addresses.

VRRP.

OSPF

What is OSPF? Process IDs, passive interfaces.

Simple OSPF.

Subnetting

Bit boundary subnetting, calculating network numbers. Exercise: Subnetting.

OSPF
