Passing Lease Pool address as a RADIUS AVP

Hello,

I am trying to add an AVP to the RADIUS accounting message sent when APM client log in in orderto store the Lease pool address given to the client.

I have tried using a Variable assign in the APM policy editor but without success.

I have also created a RADUS Virtual Server and bound an IRule to it, I can create a new custom AVP, but LTM has no visibility on the session variables in APM. The RAIDUS VServer in LTM only see a connection coming from the BIG-IP and has no way to match it to an APM session.

Is there a way to insert the Lease Pool IP to a RADIUS accounting request in APM ?

Many thanks,
