Questions # 16:

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?

Options:

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.
