Check if the IP Address of cu_gnb.conf is the same of docker-compose-basic-nrf.yaml. To edit cu_gnb.conf, type:
Check if the IP Address of gnb.sa.band78.fr1.106PRB.usrpb210.conf is the same of docker-compose-slicing-basic-nrf.yaml. To edit gnb.sa.band78.fr1.106PRB.usrpb210.conf, type:
**Step 3:** to check a virtual interface (demo-oai), type:
ip -br -c a
You should find a virtual interface (demo-oai) (as shown in figure below). This interface serves to connect the CU with OAI-AMF. You must get its IP address and name to configure the N2 interface such as two figures before.
You should find a virtual interface (demo-oai) (as shown in figure below). This interface serves to connect the gNB with OAI-AMF. You must get its IP address and name to configure the N2 interface such as two figures before.
However, if you are trying to connect to the 5G Core located on another PC, you need to configure the routes accordingly.
