* Add or delete a GTPU Tunnel.

- * GTPU provides the features needed to allow L2 bridge domains (BDs)
+ * GTPU can be used to transport Ethernet packets as its PDU type to
+ * provides allow L2 network or bridge domains (BDs)
* to span multiple servers. This is done by building an L2 overlay on
* top of an L3 network underlay using GTPU tunnels.
*
- * This makes it possible for servers to be co-located in the same data
- * center or be separated geographically as long as they are reachable
- * through the underlay L3 network.
- *
- * You can refer to this kind of L2 overlay bridge domain as a GTPU
- * (Virtual eXtensible VLAN) segment.
+ * GTPU can also be used to transport IP packetes as its PDU type to
+ * allow IP forwarding over underlay network, e.g. between RAN and UPF
+ * for mobility deplyments.
