+The `configure.sh` script relies on [gomplate](https://docs.gomplate.ca) and [gnmic](https://gnmic.openconfig.net).

+- [gomplate](https://docs.gomplate.ca) is used to generate the necessary configuration variables based on the number of spines and leaves, their type and prefix.
+- [gnmic](https://gnmic.openconfig.net) is used to generate configuration payloads per node and push it using a gNMI Set RPC.
