Hi
  Can anyone clarify me on these:

1. Is it required by the MPLS standard that we should send IP packets
with only Label 0 as bottom of stack?

2a. If the answer to (1) is yes, then should the ingress LSR push 2
labels for sending IP traffic (Top one for routing information and the
bottom one with label 0).

2b. Or is it that the ingress LSR just sends the packet with only one
label L (not == 0) and the PHP will replace that label with 0?

regards,
