GPRS Tunnelling Protocol (GTP) is a group of IP-based communications protocols defined in 3GPAA used to carry General Packet Radio Service(GPRS) within GSM, UMTS, 4G-LTE and 5G radio networks. The GTP deployment has the following features:
GTP Parsing to support single extension header
Rule matching based on the inner header (IP address, L4 Ports, TEID)
Symmetric load balancing on both inner and outer IP (v4/v6) headers
The following image shows a visual representation of the GTP deployment:
1. Configure Network/Tool port(s)
2. Enable GTP filtering
3. Configure flow with rules to filter GTP traffic
4. Verify the interfaces
5. Verify the flow
