 Since all CLI configuration commands from FRR will need to be rewritten,

 the commands easier to maintain and extend. These are the three main

 To rewrite a CLI command as a dumb wrapper around the northbound
 callbacks, use the ``nb_cli_cfg_change()`` function. This function
 accepts as a parameter an array of ``cli_config_change`` structures that
 specify the changes that need to performed on the candidate
 configuration. Here’s the declaration of this structure (taken from the
-*lib/northbound_cli.h* file):
