Basic Routing Concepts

In This Lesson We Will Learn: How a packet is forwarded and how a router learns routes Dynamic Routing Protocols Administrative Distance How packets are forwarded by routers: There are two functions that accomplish packet forwarding: path determination, and switching. Path determination is, as the name suggests, is the process the router uses to determineContinue reading “Basic Routing Concepts”

Setting Up Your Cisco Router

In This Lesson We Will Learn basic configuration of Cisco Routers Learn CLI Syntax for Routers IP Addressing Troubleshooting Setting Up Your Cisco Router Unlike switches, which are basically plug-n-play, routers do require a bit more configuration before being deployed into a network. These basic configuration tasks are listed below: Name the router Set aContinue reading “Setting Up Your Cisco Router”

IPv4 Subnetting By Hand

I wanted to do a dedicated section on IPv4 subnetting as this is typically the barrier to entry into computer networking. When I first started on this path of work, subnetting was the part I was dreading most. Even seasoned networking professionals (see Network Chuck) mention the leap from something relatively simple as the CompTIAContinue reading “IPv4 Subnetting By Hand”
