1. ping(src:45.45.0.1, dst:45.45.0.1)
2. MME emulates GTP-U instead of eNB, and send GTP-U to the SGW
3. SGW relay to PGW using GTP-U
4. PGW TUN reponse ping reply
5. PGW sends GTP-U to the SGW
6. SGW sends GTP-U to the MME
7. GTP-U decapsulates and sends ping packet to the kernel
- sudo ip tuntap add name pgwtun mode tun
- sudo ./scripts/netconfig.sh
After then,
- ./test/testcellwire
The above regression test is executed with 10.1.35.215 ip
