The current load generator simply creates/allocates TEIDs etc. internally.

You will have to modify the code to use specific TEI ranges / IP addresses that
deviate from the built-in defaults.

You can see https://gitea.osmocom.org/cellular-infrastructure/gtp-load-gen/src/commit/f4b3dd32473145d5c58d316bfadcf614802c260c/gtp-load-gen.c#L483 as example

The API functions are

* gtp_peer_gsn_create() for each GSN / peer (one per eNB for you)
* gtp_tunnel_create() for each TEID
* gtp_tunnel_ip_flow_create() for each IP flow inside a tunnel

Regards,
        Harald
