Limitations
The NRF Discovery feature has the following limitations:
-
The cache maintained is local to the library. In case of deployment with multiple replicas of REST-EP, if two Discovery or Send messages with the same discovery filter land on different pods, then both the pods trigger NF discovery.
-
This feature supports only the UDM, PCF, CHF, and AMF discovery, and load balancing. It does not support UPF discovery.
