#### Configure FQDN to DNS
For routing to Home PLMN, H-PLMN NRF, AUSF and UDM address should be used in FQDN. Today we are going to experiment on one host, so please edit the /etc/hosts file as follows.

H-PLMN 5G Core requires root privileges as it uses reserved ports such as http (80) or https (443).

- Update scp.yaml
The V-PLMN SCP needs TLS information to contact SEPP. The SCP can learn about SEPP during the discovery process, so we need to enable TLS on the client in the `defconfig` method.
The V-PLMN SCP needs TLS information to connect SEPP.
To connect SCP and NRF, the user directly specifies the client connection information in the configuration file. On the other hand, SEPP connection information can identify NF profile through NRF discovery function.
TLS information for connecting SCP and NRF can be set directly by the user in the configuration file, but not in SEPP. Therefore, in order for SCP to connect to SEPP by TLS authentication, the default configuration method as shown below should be used.
