Question
As shown in the figure, the PHP function is enabled on all routers by default and an MPLS TE tunnel RT 1-RT 2-RT 3-RT 4-RT 5 is set up between RT 1 and RT 5. See the figure for label distribution of the TE tunnel. A bypass tunnel RT 2-RT 6-RT 4 is configured on RT 2 to protect RT 3. See the figure for the label distribution of the bypass tunnel. When RT 3 is faulty, RT 2 switches traffic to the bypass tunnel. How many MPLS labels do packets on the path from RT 6 to RT 4 have? What is the value of each label?
