LINX II training course description

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 BGP and MPLS. Hands on sessions are used to reinforce the theory rather than teach specific manufacturer equipment.
A multiple choice exam, leading to the LAIT II certification, is included at the end of the course. The exam consists of 60 questions and lasts 2.0 hours.

What will you learn

• 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, simple BGP and simple MPLS.
• Evaluate and choose appropriate routing protocols for particular scenarios.
