Question: In a PLMN utilizing IPv6, what happens when an MS employs dynamic IPv6 stateless address autoconfiguration for multiple PDP contexts sharing the same IP address?
Option 1: Each MS is assigned a single, shared prefix across all its PDP contexts.
Option 2: Each PDP context, or group of PDP contexts sharing the same IP address, is assigned a unique prefix.
Option 3: The GPRS network dynamically updates the interface identifier for each PDP context.
Option 4: IPv6 stateless autoconfiguration is not supported for multiple PDP contexts with shared IPs.
Explanation: This is correct because when dynamic IPv6 stateless address autoconfiguration is used, each PDP context or a group of PDP contexts that share the same IP address is assigned a unique prefix. This ensures efficient routing and management of data packets within the network for different service contexts, even if they share an IP address.
