New Configuration Features for an Existing Device¶
If you want to fix a configuration template for an existing device supported by netlab, find the relevant configuration template (initial configurations, configuration modules), fix it, test your changes, and submit a PR.
If you want to add support for a new configuration module (example: MPLS segment routing on Nexus OS):
Read the module documentation to understand the configurable parameters;
Using existing configuration templates as a rough guide create a new configuration template (naming convention);
Find relevant test topologies in
netsim/tests
ornetsim/integration
or create your own test topologies. The test topologies should (A) test all configurable parameters and (B) test devious parameter combinations.Create virtual labs using the selected test topologies and your device. The simplest way to achieve that is to set the device type with
-d
parameter of netlab up or netlab create command.If possible, create virtual labs with mixed device types to verify interoperability of your configuration settings (example: running OSPF on unnumbered interfaces requires an extra configuration command on Arista EOS).
Update the supported platforms documentation and add caveats (if needed).
