Name: example_ndfc_easy_fabric_bootstrap_and_local_dhcp_server_unnumbered.py

Description:
Create a fabric with unnumbered fabric interfaces, configured with
inband management, local (NDFC) DHCP server, and bootstrap enabled

NOTES:

1. If you encounter the following error in the fabric's Event Analytics:

"Inband Management is supported with 'LAN Device Management Connectivity'
Server Setting set to 'Data' only. Please update the setting and retry
the management mode change."

1a. Ensure that at least 2 "External Services IPs" are configured here:

Nexus Dashboard (Admin Console) -> Infrastructure -> Cluster Configuration
  -> General -> External Service Pools -> Data Service IPs -> Add IP Address

1b. Ensure you have configured a Data Network Route here:

Nexus Dashboard (Admin Console) -> Infrastructure -> Cluster Configuration
  -> General -> Routes -> Data Network Routes -> Add Data Network Routes

1c. Change the following setting from "Management" to "Data":

Fabric Controller -> Settings -> Server Settings ->
   Admin -> LAN Device Management Connectivity

IMPORTANT! The below addressing within the range 10.1.0.0/16
assumes that the Nexus Dashboard External Data Network has
been configured to 10.1.0.0/16.  Change these script
addresses to align with your Nexus Dashboard configuration.
