! Default PPTP VPDN group

no l2tp tunnel authentication
!
interface Loopback1
ip address 1.1.1.1 255.255.255.0
!

Hello,
Is this a complete configuration of your interfaces? I am somewhat surprised that there is no ip pim command on your Virtual-template interface, meaning that the PIM/IGMP should not run on the interface and the cloned Virtual-Access interfaces at all. Even more interesting is, still, that your debug seems to implicate that the router tries sending the IGMP queries through the Virtual-Access interfaces although there is no IP Multicast activated on the Virtual-template interface... strange. Can you clarify this?
Best regards,
Peter
