Question: What happens when the SCTP establishment towards one IP endpoint fails in an NG-RAN node?
Option 1: The NG-RAN node will not establish any further SCTP connections.
Option 2: The NG-RAN node may use different source and/or destination IP endpoint(s) to establish the SCTP connection.
Option 3: The NG-RAN node will restart the entire initialization process.
Option 4: The NG-RAN node will send an error message to the UE.
Explanation: According to the 3GPP specification, when the SCTP establishment towards one IP endpoint fails, the NG-RAN node may use different source and/or destination IP endpoint(s) to establish the SCTP connection. This ensures that the SCTP connection can be established even if there are issues with the initial IP endpoint.
