Limitations
The NRF Interface Per Endpoint feature has the following limitations:
-
The NF discovery and load-balancing capabilities are available only for UDM, PCF, CHF, and AMF.
-
The dynamic configuration changes of NRF endpoints is not available.
-
Support for the liveliness check of the NRF endpoints is not available.
-
The SMF attempts the NF discovery first on the primary host. In the absence of the primary host, SMF attempts the discovery on the secondary host and switches to the tertiary if both primary and secondary are unavailable.
