1. It is also necessory to standartize representation of primitive
a) IP4, IP6 [variants: string which can be passet to net_pton]
b) IP6Prefix [variant ??? -- some standart text representation]
c) Mac address [ variant: canonical IEE 802 string representation,
i.e. http://en.wikipedia.org/wiki/IEEE_802 ]
d) Octets [ base64 string ? ]
e) IFID [base64 ? hex string ?, integer ?]
) Note: The outbound request will only use attributes from the request
list. If you think attributes should be ) included from multiple
lists, please explain why.
I.e. this is mean, that if we want to receive value of some attribute
from json application server, we must
send one at first ?
Let we have client, which send DHCP Offer message to radius. Radius
must response with IP address,
which allocated from pool. Of course incoming message does not
contains YOU_IP_ADDRESS attribute.
So, it will be impossible to request ip address from json server, or I
miss something ?
