Scenario:

From PE8 router, what is the label action used to reach the P2 loopback 0 interface 10.0.2.1/32?

Answer: C

show mpls forwarding-table , find prefix 10.0.2.1 and you will see there under outgoing Label “Pop Label” (This is actually logic because the prefix is directly connected and therefore the packet will forward without label). If the router should forward any packet to that prefix, the packet should be received with Local label on PE8 (Local Label = 35), the router will remove it and forward it without Label.
