SUSE Certified Engineer - Connecting Network Namespaces with Advanced Networking
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.
