RADIUS authentication for VPDN

[jon.starling]

I'm using RADIUS to authenticate PPP sessions coming into a 7200 router over L2TP (using BT's 21C WBMC product). However for every connection for an example user of user@domain the RADIUS server sees one Access-Request for the domain only and then another for user@domain. Is there a way to configure the 7200 to only send the user@domain Access-Request and not the one for just the domain?

Hi Jon,

Try using the below commands,

Step 1 Router(config)# vpdn-group group-number

Step 2 Router(config-vpdn)# authen before-forward

Step 2 specifies that the entire structured username be sent to the radius server the first time the router contacts the radius server.
