mpls Out Segment Push Top Label

1.3.6.1.3.96.1.6.1.3

This value indicates whether or not a top label should be pushed onto the outgoing packet's label stack. The value of this variable must be set to true if the outgoing interface does not support pop- and-go (for example an ATM interface) or if it is a tunnel origination. Note that it is considered an error in the case that mplsOutSegmentPushTopLabel is set to false, but the cross-connect entry which refers to this out-segment has a non-zero mplsLabelStackIndex. The LSR MUST ensure that this situation does not happen
