Scenario:
From PE8 router, what is the label action used to reach the P2 loopback 0 interface 10.0.2.1/32?
A. Swap label 35 with label 16004
B. Push label 16004
C. Pop label 35
D. Pop label 16009
E. Push Label 16009
F. Swap label 35 with label 16009
Correct Answer: C
Explanation/Reference:
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.
