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 available after 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.
