IPv6 RADIUS Accounting

How to enable IPv6 RADIUS accounting of Delegated-IPv6 Prefix with Cisco IOS >15

I’m struggling to understand why on accounting packets of my Cisco ASR1001-X with a dual stack configuration, the Delegated-IPv6-Prefix is not present at all.

In my configuration I’m using DHCPv6 PD and Delegated-IPv6-Prefix sent from the RADIUS server in Access-Accept response in every request.

I found that interesting article of ipspace and found the reason about it.

Basically you have to enable the feature with this command, keep in mind that it’s only supported from IOS 15.1.

aaa accounting include auth-profile delegated-ipv6-prefix

Here a screenshot of the Cisco documentation and Link to the official documentation about that command.
