Q1. Suppose a connection is originated between end points A and B,
with 3 router hops (R1, R2, R3) in between. So in essence, A sends

(destination local router).
a) What happens with the flow label of a connection, if
R1 is not flow capable and R2, and R3 are? Explain.
b) What happens with the flow label of a connection, if R1 is flow
capable, R2 is not, and R3 is? Explain.
c) What happens with the flow label of a connection if R1, R2 are
flow capable and R3 is not? Explain.
