MPLS Forwarding Settings 
This window is used to display and configure the MPLS forwarding settings. 
The Static FTN Settings section is used to add or delete a static FEC-To-NHLFE Map (FTN) entry. FEC stands form 
Forwarding Equivalence Class and NHLFE stands for Next Hop Label Forwarding Entry. At the ingress Label Edge 
Router (LER), the incoming IP packets that are classified to the Forwarding Equivalence Class (FEC) will be pushed 
with the MPLS label and forwarded to the next hop according to the FEC-to-NHLFE (FTN). 
The Static ILM Settings section is used to add a static Incoming Label Map (ILM) entry. At LSR, the incoming MPLS 
packets that are matched to the incoming label will be processed according configured ILM action. The label operation 
is either swapping the incoming top label to configured outgoing label or popping the top label and then forwards the 
packets to the next-hop.
