Config Lab: IPv4 Addresses 5
Config Lab: IPv4 Addresses 4
Practice makes memory. So, time for some practice with IPv4 address configuration on routers. This post is a traditional Config Lab exercise: you start with a network diagram and some planned IPv4 subnets. Your job: do some subletting math and configure
Config Lab: IPv4 Addresses 3
With enough repetition, you should be able to imagine a small network of routers, choose a subnetting plan, choose addresses for the router interfaces, and configure those addresses, all pretty much as fast as you can write or type. This
Config Lab: IPv4 Addresses 2
Repetition helps when learning IP addressing and subnetting. The next lab gives you more reps with subnetting math and with configuring router IP addresses. If you already know the math, make this one a speed test, and find out how
Config Lab: IPv4 Addresses 1
The next lab combines a little bit of subnetting math with IP address configuration. If you know how to calculate the IP addresses in a subnet and how to configure IP addresses, make this one a speed test. See how
Config Lab: L2 EtherChannel 2
Both layer 2 EtherChannel and layer 3 EtherChannel use the same set of commands to create the channel. You have the option to use static configuration or one of two dynamic protocols to negotiate the formation of a trunk (LACP
Config Lab: L2 EtherChannel 1
EtherChannel takes a big step towards improving STP. With two links between switches, but without using EtherChannel, each instance of STP could use only one of the links blocking the other link. With a layer 2 EtherChannel, STP treats the

LAN switches use many default settings that work without you having to do anything, and oftentimes, you can leave those default settings as-is. However, with Spanning Tree Protocol (STP), and its better cousin Rapid STP (RSTP), you should configure some
