I would imagine that to be dependent on the VPN implementation. If the CE and PE routers actually exchange label information, then, I would imagine the label to be swapped. Otherwise, if labels are exchanged independently among PE routers (iBGP peers)and among CE routers (possibly through the PE routers), then, there would be 3 labels in the scenario you described. To my knowledge, MPLS capable CE devices have not been addressed much at all, although that is mentioned as a possibility in the VPN drafts. -Vidya > -----Original Message----- > From: Shahram Davari [mailto:Shahram_Davari@pmc-sierra.com] > Sent: Wednesday, May 09, 2001 2:16 PM > To: 'mpls@uu.net' > Subject: BGP/MPLS VPN PE LSR > > > Hi, > > In an BGP/MPLS VPN scenario if a CE router sends an MPLS > packet rather than an IP packet to a PE router, the PE router > should still push 2 labels.
