SUSE Certified Engineer - Connecting Network Namespaces with Advanced Networking

  • 3 Learning Objectives

About this Hands-on Lab

In this hands-on lab, you’ll be working to better understand network namespaces, Ethernet bridges, VETH (virtual Ethernet) pairs, and how you can create them and connect them to form infrastructure. You’ll first create a couple of network namespaces and verify their configuration. You’ll then populate the network namespaces with Ethernet bridges, assign IP addresses to the bridges, and attempt connectivity between the network namespaces.

You’ll realize that there is more connective configuration needed, and then set up a VETH pair and connect that between the 2 network namespaces’ Ethernet bridges, and then verify they can reach each other via the VETH pair and Ethernet bridges.

**Note:** Make sure to elevate to `root` once logged in.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Set Up and Test Network Namespace Connectivity
  • Create and verify network namespaces.
  • Display and configure local interfaces.
  • Query and verify the interface status.
Populate Network Namespaces with Ethernet Bridges
  • Create network bridges in each network namespace.
  • Add IP addresses to the network bridges.
  • Confirm IP address and network bridge status.
  • Attempt to test connectivity between network namespaces.
Connect Network Namespaces with VETH Pairs
  • Set up VETH pair connecting links between network namespaces.
  • Connect the VETH pair to the network bridges.
  • Configure the links in each network namespace.
  • Test connectivity between the network namespaces.

Additional Resources

In this lab, you're a mid-level systems operator who has been tasked with becoming more familiar with virtual infrastructure in preparation for using containers for tasks in the near future.

You'll be initially setting up network namespaces, creating them, testing them, checking their details, and running commands that show you the details of their configuration.  You'll then be connecting the namespaces using network bridges and VETH pairs so you can verify they can connect with each other.

What are Hands-on Labs

Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
