"Network is unreachable" when connecting to ORAN-SC near-RT RIC

hoangtuansu commented 1 year ago

Issue Description

srsRAN gNB (commit 5e6f50a20) failed to connect SCTP socket of ORAN-SC nearRT-RIC while commit c54bcfe works. I followed the tutorial from https://docs.srsran.com/projects/project/en/latest/tutorials/source/flexric/source/index.html and only replace FlexRIC by ORAN-SC nearRT-RIC.

Setup Details

Server host srsRAN gNB and Open5GS: Intel(R) Xeon(R) Gold 6348 CPU @ 2.60GHz, 96 cores, 192 threads, 256 GB RAM, 500 Gi SSD.

Expected Behavior

The connection should be successfully created as it did with commit c54bcfe

Actual Behaviour

Only NGAP messages are exchanged. 2 other files (gnb_e2ap, gnb_mac) are empty.

Steps to reproduce the problem

srsRAN commit 5e6f50a20 ORAN-SC nearRT-RIC H version, deployed on K8s and exposed its pod, i.e. e2term, via a NodePort service.

Close. Fix by adding bind_addr to config file.

@hoangtuansu Which release of the O-RAN SC did you use? Was it the h-release?

Hello. I was installed near RT RIC from bellow link and all pods are ok running: https://gerrit.o-ran-sc.org/r/gitweb?p=ric-plt/ric-dep.git;a=blob;f=new-installer/README.md;h=a4cb085c12a61bfd7421c8b04aee147232688c42;hb=HEAD

Also i set my mcc and mnc in near RT RIC yaml file. ric ip an aux ip are also set as ip of my near RT RIC machine.

But have this error: ./gnb -c gnb_zmq_e2.yaml

@hoangtuansu can you help me? what should I set for bind_addr , e2 addr , ricip and auxip: and e2 port? if i installed srsRAN on 192.168.75.183 , nrt ric on 192.168.75.197 vm with docker interface 172.17.0.1 , and kubectl get svc -n ricplt show : service-ricplt-e2term-sctp-alpha NodePort 10.101.146.165 36422:32222/SCTP 19d
