Does mpd (multi-link PPP daemon) support IPv6?

[Blue]

Hi, all:

I want to know whether mpd (multi-link PPP daemon) could possibly 
support IPv6. When I want to establish a PPTP connection with a PPTP 
server running mpd, could I use IPv6CP instead of IPv4CP to set up the 
PPP? If it supports, how could I configure the related parameters in the 
configuration files? I could only find the ipcp syntax.

Best regards,
