Configuring the Discovery Service

This section describes how to enable the discovery service for the NRF.

To configure the NRF Discovery and PCF locality and associating them to the NRF Endpoint, use the following configuration in the Policy Ops Center console:

config 
     profile 
       nf-pair 
         nf-type [ type ] 
           type nf_type 
         nrf-discovery-group -> /group/nrf/discovery/name 
         subscription-enabled subscription_status 
         subscription-extension extension_value 
         locality 
           client -> /service-registration/profile/locality 
           preferred-server server_name 
           geo-server geo_server 
           end 
NOTES:
  • type nf_type – Specifies one or more NF types such as AMF, CHF, PCF, and UDM as the network element profile.

  • subscription-enabled subscription_status – Indicates if PCF is enabled to subscribe to notifications related to the discovered service.

  • subscription-extension extension_value – Specifies the duration (in minutes) for which the subscription is extended.

  • preferred-server server_name – Specifies the preferred server locality information. Preferred server locality is the locality that is considered as the locality of preference during the corresponding NF discovery.

  • geo-server geo_server – Specifies the geo-server locality information. Geo-server locality is a geo redundant site for the preferred locality and is used as the next suitable server locality after preferred locality, during NF discovery.
