PPP Multilink... cannot find attribute... ??

Hi,

I  was  looking at all the attributes to do PPP multilink but 
cannot seem to  find how  to do it.   I looked at all the attributes.

This  will  be used for  PPPoE  DSL sessions.  I use a SQL  databasese  to  
process  my users' attributes.

Does anyone have an idea?

Martin
