| SD-Core VM Preparation |
| ''''''''''''''''''''''' |
| |
| - To Expose External IP and Port of amf service, update sd-core-5g-values.yaml :: |
| |
| amf: |
| # use externalIP if you need to access your AMF from remote setup and you don't |
| # want setup NodePort Service Type |
| ngapp: |
| externalIp: 10.10.1.1 #ip address of DATA_IFACE |
| port: 38412 |
| |
| - Deploy 5g core with options DATA_IFACE=ens1f0 and ENABLE_GNBSIM=false, sample command:: |
| |
| $ ENABLE_GNBSIM=false DATA_IFACE=ens1f0 CHARTS=release-2.0 make 5g-core |
| |
| - Make sure that ``DATA_IFACE`` connected with UERANSIM VM |

| |
| - Single interface is used for user plane traffic towards UPF and also control plane |
| traffic towards AMF |
| |
| - Add following route in routing table for sending traffic over ``DATA_IFACE`` interface :: |
| |
| $ ip route add 192.168.252.3 via 10.10.1.1 |
