Kireeti, I'm looking at your slides from the joint meeting, in particular slide #3, where you say at thye bottom: "Corollary: such labels MUST NOT reach the top of stack (by popping labels above them)" How is that backwards compatible. If you have an old LSR, that don't know to look at the bSPL or eSPL underneath the top label. I assume that the top label will be swapped and the packet forwarded. What is the pen-ultimate LSR is "old" and just pop the top label, how can the PE sort this out? /Loa -- Loa Andersson email: loa@pi.nu Senior MPLS Expert loa.pi.nu@gmail.com Bronze Dragon Consulting phone: +46 739 81 21 64
