Default DNN Support in HR Roaming

In the HR roaming scenario, the vSMF supports the use of default DNN to avoid listing or configuring all the DNNs used by the roaming partners.

The DNN validation is disabled for the visitor-hr calls received by the vSMF. From the default DNN profile, the virtual DNN configuration is used toward vCHF, vUPF, and RMGR for vUPF selection.

To configure the default DNN profile, use the following CLI configuration:

config 
   policy dnn policy_name 
      profile profile_name 
   exit 
exit 

To configure the virtual DNN name, use the following CLI configuration:

config 
   profile dnn profile_name 
      dnn virtual_dnn_name network-function-list [ chf | rmgr | upf ]  
   exit 
exit
