   I think the latter, but I'm not sure.   
      
   Here's a good reference, including all the RFC numbers at the end:   
      
   http://www.networksorcery.com/enp/protocol/gre.htm   
      
   A (possibly) good place to ask a question like this is   
   comp.dcom.lans.ethernet   
      
   This isn't an ethernet question, though, its an IP question, so I don't know   
   whether they'd answer or just say go elsewhere.   
      
   Looking at RFC 2637, 1.3.2, there's a key in each GRE packet indicating what   
   session the PPP packet belongs to.
