Following is what you need for this book:

To get the most out of this book, some basic hands-on network operation knowledge and Python knowledge is recommended. Most of the chapters can be read in any order, except for Chapter 4 and Chapter 5, which introduce base technologies that will be used later in the book.

mastering-python-networking-fourth-edition's Issues

Does anyone care about or maintain this repository?

The topology labs don't build because the yaml files are wrong, I've taken the time to correct them as much as I could and submitted a pull request over a month ago which has been ignored. This is frankly unacceptable for a book that was published only just this year. If the intention is that readers/students follow along with the lab, then the repository should be maintained. I can't recommend this book to anyone in the current state of this repository if the CML lab doesn't even build.

Work with latest CML version

The latest CML release replaced NX-OS (nxosv) image with NX-OS9000 (nxosv9000), more information here. Thank you GRana2codes for submitting the PR. However, after merge a error was reported by a user:

"
ERROR:

Failed: Error importing topology file: Node n4 lax-cor-r1 interface i1 Interface #1 label Ethernet2/1 is not valid for node definiton nxosv9000: defined interface label is Ethernet1/1; Node n4 lax-cor-r1 interface i2 Interface #2 label Ethernet2/2 is not valid for node definiton nxosv9000: defined interface label is Ethernet1/2; Node n4 lax-cor-r1 interface i3 Interface #3 label Ethernet2/3 is not valid for node definiton nxosv9000: defined interface label is Ethernet1/3; Node n5 nyc-cor-r1 interface i1 Interface #1 label Ethernet2/1 is not valid for node definiton nxosv9000: defined interface label is Ethernet1/1; Node n5 nyc-cor-r1 interface i2 Interface #2 label Ethernet2/2 is not valid for node definiton nxosv9000: defined interface label is Ethernet1/2; Node n5 nyc-cor-r1 interface i3 Interface #3 label Ethernet2/3 is not valid for node definiton nxosv9000: defined interface label is Ethernet1/3.
"

I am going to revert the merge for now and created this issue to track progress.

Workaround for now: please use this topology file for import but update the node definition to use nxosv9000 image if you are using brand new CML 2.6, as nxosv is no longer included in the new refplat ISO image. If you want to use the old nxosv image, you can still download it. If you have have migrated to CML 2.6 from an ealier version, this is not applicable to you.
