Hi,
From "draft-kompella-ppvpn-l2vpn-02.txt":
 
"In this document, we take a different approach: we postulate that the
   network layer is IP, and base Layer 2 interworking on that.  Thus,
   one can choose between pure Layer 2 VPNs, with a stringent Layer 2
   restriction but with Layer 3 independence, or a Layer 2 interworking
   VPNs, where there is no restriction on Layer 2, but Layer 3 must be
   IP....."
 
Could anyone explain me why "IP only"?
 
Thanx
 
Daniele
