What do you mean with "by request" - is it created by policy or packet
arrival?
I think i may be able to visualize this, if ia m right -  what is
happening is a packet gets redirected to this device which then
does some MPLS work on it before sending out some device with proper
encapsulation? Is this typically an IP packet?
