Question: When modifying a QoS rule using the QoS-Rule-Install AVP, what happens to the previously provided Tunnel-Information AVP if a new one is included?
Option 1: The newly provided Tunnel-Information AVP replaces the previous one for all QoS rules within the BBERF.
Option 2: The newly provided Tunnel-Information AVP is appended to the previous one, creating a list of tunnel information for the modified QoS rule.
Option 3: The previously provided Tunnel-Information AVP remains unchanged for the modified QoS rule unless explicitly deleted.
Option 4: The inclusion of a new Tunnel-Information AVP has no effect on previously installed QoS rules.
Explanation: According to the specifications, when QoS rules are being modified and a new Tunnel-Information AVP is provided, it replaces the previously provided Tunnel-Information AVP for the modified QoS rules. This ensures that only the latest tunnel information is applied to the updated rule, maintaining consistency in network configuration.
