— Exhibit –Given the topology shown below:
CE1-PE1-P-PE2-CE2
PE1 and PE2 have two equal-cost RSVP LSPs (LSP-1 and LSP-2). They form a Layer 2 circuit
between CE1 and CE2. You are asked to map their traffic to take LSP-1. The exhibit shows the
current configuration of PE1. The correct configuration has been completed on the other routers.
Which two configurations must be added to PE1 to ensure that this traffic is always carried on
LSP-1? (Choose two.)
