Networking Fundamentals
Understand how computer networks carry data, from cabling and switches to IP addresses and the internet, and build, test and document a small office network with confidence.
- Foundation
Design, configure and optimize large campus and multi-site networks using multi-area OSPF, BGP, route redistribution, advanced spanning tree, first hop redundancy and policy-based traffic control.
The Enterprise Routing & Switching course in Doha, Qatar is an advanced program for engineers who already run networks and now need to scale them across campuses, branches and data centers. It moves beyond single-area designs into multi-area OSPF, EIGRP, eBGP and iBGP, route redistribution and filtering, and policy tools such as route maps and prefix lists. On the switching side, it covers Multiple Spanning Tree, Layer 3 switching, EtherChannel tuning and gateway redundancy with HSRP and VRRP.
Every topic is reinforced through multi-device lab topologies that mirror enterprise designs, including hierarchical core, distribution and access layers and dual-homed internet edges. Participants plan changes, implement them, then break and repair them to understand failure behavior and convergence. Design discussions weigh scalability, resilience and operational simplicity, and introduce VRF-Lite, GRE tunnels and SD-WAN concepts. Organizations can schedule the course as an in-house program aligned with their own architecture and upgrade plans.
By the end of this course, participants will be able to:
Design hierarchical campus networks with resilient core, distribution and access layers
Configure and tune multi-area OSPF, including area types and summarization
Implement eBGP and iBGP with path attributes for multi-homed internet edges
Control routing with redistribution, route maps, prefix lists and policy-based routing
Deploy MST, Layer 3 EtherChannel and HSRP or VRRP gateway redundancy
Segment traffic with VRF-Lite and connect sites using GRE and IPsec tunnels

Large organizations in Qatar, including government ministries, banks, energy producers, hospitals and universities, operate networks that span multiple buildings, cities and data centers. Smart-city developments and the expansion of digital public services under Qatar National Vision 2030 demand networks that stay available and scale smoothly. Engineers who can design and run resilient routing and switching architectures help these organizations keep critical services running, support secure connectivity between sites and reduce dependence on outside specialists.
Join a scheduled class at our training center in Doha or attend live online. For organizations, the course can run as an in-house program at your premises or online, tailored to your sector, examples and schedule.
It is an advanced course in Doha for engineers who build and manage large networks. It covers enterprise campus design, multi-area OSPF, EIGRP, BGP, redistribution, advanced spanning tree, gateway redundancy, VRF-Lite and site-to-site tunnels through multi-device labs.
It is designed for network engineers, senior administrators, architects and WAN or data center engineers who already configure routers and switches daily and need to design, scale and troubleshoot multi-site enterprise networks.
You should be comfortable with CCNA-level topics such as subnetting, VLANs, trunking, static routing and single-area OSPF, and have hands-on experience with a router or switch command line. Newer engineers may find the CCNA preparation course a better first step.
Yes. It can be delivered at your premises or online and tailored to your sector, your network architecture and planned projects, and your schedule. Contact Leaders Training Center to plan an in-house program for your engineering team.
