Radius Accounting for L2TP's LAC

[ritsang]

Hi,

We've setup the VPDN (using L2TP) using RADIUS as AAA server. The authentication part has no problem for both LAC and LNS using two RADIUS servers.

For example when the user login using abc@cisco.com, the LAC will authenticate to LAC radius server using cisco.com and then the LNS will authenticate to the LNS radius server using the full name abc@cisco.com.

But for AAA accounting, both the LAC and LNS will use abc@cisco.com as the user ID to send the RADIUS accounting. In the LAC RADIUS server, only user ID cisco.com exists. My RADIUS servr will drop this accounting packet. Is it possible to configure the LAC router to use cisco.com as the user ID to send the RADIUS accounting?

Thanks,

Rico.
