No. router1 (the LAC) also sends accounting requests, but it includes
the vpdn tunnel information.

Hmm, are you using virtual-profiles on the LAC? If you are (I strongly
assume you do), you might be able to disable accounting globally

aaa accounting network default none

and then define a non-default method list which you reference on the
vtemplate:

aaa accounting network DIAL start-group group radius
!
int virtual-template 1
 ppp accounting DIAL

I am not sure if this will work, but it is worth a try.

If it doesn't, can't you ignore the acct-records from the LAC which
contain VPDN/tunnel information?
