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.
LINX II training course details
Who will benefit:
Network engineers.
Prerequisites:
LAIT I attendance and 55%+ exam score OR LAIT I exam only and pass (70%+) OR CCNA and take LAIT I exam on this course.
Duration
5 days
