Description

Hi,
I have tried to add more gNbs and MECs; however, after adding a fourth, I get this error: "Address contains no value -- in module (inet::Udp) MultiMecHost5.gnb2.udp (id=360), at t=0.009000752s, event #680"

I am using the examples: multiMECHost, requestResponseApp. Do you know why this error occurred or what configuration I am doing wrong? I tried to add the x2app, as explained in the example, but the error persists.

Attached the ini, ned. configuration "[Config MultiMec6]" has the 4 MECs , and "[Config MultiMec5]" has there three MECs.

Thank you!

Research direction

Start by comparing the attached ini and NED configuration for MultiMec5 and MultiMec6, then reproduce the failure in the multiMECHost and requestResponseApp examples. Inspect the setup around MultiMecHost5.gnb2.udp and the attempted x2app configuration; done means identifying why the fourth MEC leaves the UDP address unset and confirming the corrected configuration no longer raises the error.
