<R1,R2,R3,R6,R7> is the Label Switching Path (LSP) for this network, where R3 and R6 are not
directly connected routers. Let Lij be the label value for the packet sent from router Ri to router
Ri, (e.g., L12 is the label value for packet sent from router 1 to router 2).
What would be the label(s) in the packet sent by the following routers: (1) R2 (2) R3 (3) R5
Show all labels that would be contained in the packet. Assume penultimate hop popping is being
used. Show your answer as follows:
Label 1
Label 2
