Open5GS – NRF Setup

We covered NRFs last week, but I thought I’d cover actually configuring the NRF on Open5GS,

We’ll first off need to install the NRF,

$ sudo apt update 
$ sudo apt install software-properties-common 
$ sudo add-apt-repository ppa:open5gs/latest 
$ sudo apt update 
$ sudo apt install open5gs

Next up we’ll need to configure the NRF on the domain “nrf.5gc.mnc001.mcc001.3gppnetwork.org”, for this we’ll edit /etc/open5gs/nrf.conf and set the binding IP.

nrf:
  sbi:
    - addr:
       - 10.0.1.252
      port: 7777

Now for each Network Element we’re bringing online we’ll need to point it at our NRF’s address (or IP).

nrf:
  sbi:
    - addr:
       - nrf.5gc.mnc001.mcc001.3gppnetwork.org
      port: 7777

But there’s another very similar section inside the definition file, but this defines which IP the NRF client will listen on,

And that’s it,

From the log in /var/log/open5gs/nrf.log you see connections coming in,
