Here AMF, NSSF, UDM, UDR, AUSF are common to all slices. SMF and UPF in S-NSSAI 2 and 3 have same NRF hence both UPFs are discoverable to both SMF. You can verify in the logs that both SMFs are successfullt associated to both UPFs in S-NSSAI 2 and 3. Here number of SMFs/UPFs for registered under single NRF is part of operator network planning.<br/>

We are using 3 different ran simulators viz.ueransim, rfsimulator and gnbsim for slice 2,3 and 4 repectively. Each of them has there set of features, and one can use as per need basis. You can pull docker images from official repositories as below -

OAI 5G CN also supports UE with multiple slice, Appereantly ransimulators that we have validated are does not support UE with multiple slice at a time.
Hence, we have validated this feature using commercial testing tool [dsTest](https://www.developingsolutions.com/products/about-dstest/). This test case is integrated in our [CI pipeline for NSSF](https://jenkins-oai.eurecom.fr/view/CN5G/job/OAI-CN5G-NSSF/) and AMF. Pipeline triggers deployement scenario as shown in figure below with two slices. During PDU session establishment request, AMF queries NSSF for NSI information with appropriate NRF Id. And then again corresponding SMF anf UPF is slected in the NSI, based on S-NSSAI provided. You can verify this scenario from the [pcap](https://jenkins-oai.eurecom.fr/view/CN5G/job/OAI-CN5G-NSSF/lastSuccessfulBuild/artifact/docker_logs.zip).
