Hi List,<br>
<br>
I have a request packet arriving with contents "RELAY-MSG"
containing data I can to verify and use in a 'host-identifier
option' line.<br>
<br>
The option I want to extract is the 15 character long interface-id,
which is 1 relay encapsulation deep in the packet.<br>
<br>
Very much like:<br>
host-identifier option <i>dhcp6.interface-id</i> "BIGSTRING";<br>
<br>
However I can't find any option to extract data from the inner
relayed messages.<br>
<br>
(That "BIGSTRING" is added by the NSP to allow me to 'authenticate'
the end-user by sub-interface on a cisco router.)<br>
<br>
Suggestions? Solutions?<br>
