[strongSwan] Configuration Payload for IP Address Assignment Error Cases

[Pisano, Stephen G (Stephen)]

Hi:

Considering use cases where a strongSwan client is talking to a non-strongSwan-based SeGW, I wonder how a strongSwan client responds in the following situations:

1. the SeGW replies with an configuration payload reply containing and "empty" address (length = 0)
2. the SeGW replies with an INTERNAL_ADDRESS_FAILURE notification
3. the SeGW does not generates a configuration payload reply nor a failure notification (e.g., it does not provide any support for configuration payload)

Thanks,
Stephen
