Config mode questions



For a Request/Reply exchange in Config mode:

1. If the gateway wants to send its response to an INTERNAL_IP4_SUBNET
attribute request how the response will be sent for both subnet and mask if
the attribute length is mentioned into RFC to be 0 or 4 octets for this
attribute. How do you specify the mask for the subnet protected?

2. APPLICATION_VERSION attribute can be 0 length or more. Is this one
required to be multiple of 2 or 4 octets? If not, when someone request
SUPPORTED_ATTRIBUTES, the result should be multiple of 2 (which might not be
in case your APPLICATION_VERSION is 7 bytes length for example)

3. Are the attributes required to be aligned at 4 bytes?

Thanks in advance.
