AFAIK

Within the scope of RFC 2574 bis , never heard about  : "  i have heard 
there is a workaround for such scenarios wherein...a sort of virtual router 
that mimics a L3 CE device is created on the PE of the
provider which connects to L2 CE..and the VPN in turn starts from the PE 
connecting to this PE. "

Since the CE in this case is not L3 speaker so we need to define statically 
the routing ,
on the PE we use static routing and on the HOST's (connected through the 
switch ) using
a default routing pointing to the PE port .
