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:
