Each component (EPC, eNB, gNB) has its own configuration file.
These config files are passed as arguments of the run command line, using the option -O \<conf file\>
Some config examples can be found in the following folder:
https://gitlab.eurecom.fr/oai/openairinterface5g/-/tree/develop/targets/PROJECTS/GENERIC-LTE-EPC/CONF
Also base config files can be found here:
[enb conf file](https://gitlab.eurecom.fr/oai/openairinterface5g/-/blob/rh_doc_update_3/doc/testing_gnb_w_cots_ue_resources/enb.conf)

TO DO : attach base confif files
The **REFERENCE** files for eNB and gNB, **used by the CI**, can be found here:

These files have to be updated manually to set the IP addresses and frequency.
**ATTENTION** : an **EXTERNAL** clock is used to sync the eNB and gNB,
whether the clock is internal or external is defined in the configuration files (!! details needed !!)
