#How to create new lab in eve ng how to
How to read and create the network sectionįormating the network this way allowed for a more concise looking format for the bridges that are typically created in most EVE topologies.
Interface: # each interface you will connect in the topology to another node or network element Num_interfaces: 8 # number of interfaces you want on the node Template: vios # EVE template for the node you will provision in the topology # This dictates how the nodes will be configured and connected in the lab topology map Lab_description: Creating the topology with an ansible playbook # Fill in the name of the lab as you want it to appear in EVENG I want a smaller file to fill in for a large topology # attempting to make create the topology_details a bit easier.
#How to create new lab in eve ng mac
The device mac address will simply increment the 3rd octet from the right side by 1 number each time the Jinja template loops.UUIDs are generated somewhat randomly with the use of the random range function in Jinja combined with the function to convert that number to a UUID.A delay count has been added to the templates so that you can simply turn on all nodes in EVENG at the same time and they will start in 30 second increments and hopefully not clog your CPU.This way the incremental increase is done for you. Also removed some keys that were not needed and instead placed those into the Jinja template because they should be incremented up anyway. This is a little shorter from a total lines perspective. I updated the playbook changed up the YAML file used to create the UNL file.Works with any ansible version 2.9 and up. These are found in the /node_templates folder. Jinja templates are used to format the UNL file and I have created several templates for common router and switch templates I use in EVENG. This file can be copied to your /opt/unetlab/labs/ directory on your EVE server.īelow is an example of how to format the lab_facts.yaml. unl file under the /eveng_unl_file folder. This helps avoid the clicking and selecting and refreshing of the EVE topology page.įor now, the topology_details.yml will be filled out manually with the router or switch templates available to you in your EVE environment. The idea behind this effort is firstly to quickly generate a lab topology with all the connectivity in place.
