   5. 2023-05-09:
      1. Q-to-James: summary of what you presented in TOC (1 min) and let's raise question to all for input to integration project.
         1. Xtesting is used in integration project now (already for 6 months or so). Xtesting works also with robot test cases.
         2. James working in this integration for the test cases that are already in it/test. Infrastructure team also contributed O2 releated robot test cases (requires o-loud).
         3. Input from other subprojects, incl. our near-RT RIC project?
      2. James needs some hints on how to run the existing robot test cases in it/test related to missing env variables: GLOBAL_INJECTED_E2MGR_USER and APPMGR_ENDPOINT.

   1. code changes, but difficult to test as difficult to change order of IEs in message.
   2. 2023-06-06: Added unit tests (integrated in image building) - did some changes in the stubs (based on environment variables). Next step looking into this.
8. Dhiraj
   1. 2023-05-23: ipv6 - Alexandre working on this: RIC-985. Note that this requires re-creation of most container images.
   2. 2023-06-06: ipv6 fix is merged. Dhiraj tried with this new version. Containers start. Good. Investigation continues - most likely fix needed in routing manager ([ brackets cause issues)and E2T (crashes to be fixed). 
9. Alexandre
   1. 2023-05-23: no news
   2. 2023-06-06:
      1. fixed IPv6 support in RMR - works in IPv6 only case and in case of providing specific IPv6 address. Routing mgr might require additional work.
      2. seems also to be a bug in interface name solution in RMR. Remember to cretae a JIRA item.
