The current laboratory acting as a continuation practical session of the last week laboratory, it has the next main learning goals: learn how to create and remove an emulated network topology, using script files; learn how to emulate more realistic network conditions, such as latency and jitter, using the Linux Traffic Control (tc) tool; and learn how the spanning tree protocol avoids loops within a local network.

Laboratory session to introduce the virtual machine (VM) that it will be used along the course. Using the previous VM: learn how to create an emulated host using the concept of Linux NameSpaces; learn how to add, configure and enable the network interfaces on each host; learn how to create a network link connecting two interfaces; learn how to create a Linux bridge (or switch) that will be connecting the two hosts of the current topology; learn how to add to the switch the associated interfaces of the two network links previously created; and learn how to test the current emulated (or virtualized) topology.
