RFC 4349 and RFC 4591: FR negotiation

RFC 4349 (L2TPv3 HDLCPWs), clause 4.1

All packets are passed in a largely transparent manner over the 
HDLCPW.The *negotiations* and
signaling of the specific protocols transported over the HDLCPW *take 
place between the Remote Systems*.


RFC 4591 (L2TPv3 FRPWs), clause 5

There is a one-to-one mapping (DLCI mode) between a Frame Relay PVC and 
an FRPW. The egress
LCCE re-writes the DLCI and regenerates the FCS.


Then, when DLCI mode is used (FRoPWs), does FR negotiation take place 
between remote systems (like HDLCPWs), or between each remote system and 
its LCCE?
