Question 210

(0)

Which of the following about the label stack of a VPRN is FALSE?

Question 201

Click the exhibit. This output is from router R4. Service 333 is a VPLS. Why might the peer 10.10.10.1 have the same value for IngLbl and EgrLbl?

The labels are of local significance only, so other routers can use the same value.

10.10.10.1 has yet to send its own unique label.

Router R4 is using the same tunnel to send and receive to 10.10.10.1.

The service on 10.10.10.1 is down, so it is rejecting packets.
