Build a strong foundation in computer networking and learn how modern Ethernet LANs operate. This course introduces the TCP/IP model, Ethernet, WAN and routing fundamentals, Cisco IOS, switch configuration, VLANs, Spanning Tree Protocol, RSTP, and EtherChannel. By the end of the course, you will understand how switches forward frames, how VLANs divide networks, how Layer 2 loops are prevented, and how multiple links can be combined for greater reliability and bandwidth.
Explore courseDevelop the IPv4 addressing and routing skills needed to design, configure, and troubleshoot real networks. This course takes you from subnetting fundamentals through subnet design, router operation, IPv4 interface configuration, static routing, inter-VLAN routing, host addressing, and routing troubleshooting. You will learn how to calculate networks and subnets, configure IPv4 connectivity, understand how routers make forwarding decisions, and identify common routing problems.

Advance your routing knowledge with OSPF and IPv6. This course explains how routers dynamically exchange routes using OSPF and how modern networks implement IPv6 addressing and routing. You will learn OSPF neighbor relationships, route selection, configuration and verification, IPv6 addressing and subnetting, router and host IPv6 configuration, and IPv6 routing. By the end of the course, you will be able to understand, configure, and troubleshoot core OSPF and IPv6 concepts required for the CCNA 200-301 exam.
