Which of the following statements is incorrect?
- MPLS labels can correspond to a Layer 3 destination address, QoS, source address, or Layer 2 circuit.
- MPLS does not require a routing table lookup on core routers.
- MPLS works in IP networks only.
- MPLS uses labels to forward packets.
Explanation: This statement is incorrect because MPLS was specifically designed to be multiprotocol, meaning it can support multiple Layer 3 protocols beyond just IP. It is capable of forwarding non-IP protocols because the labeling technology is applicable to any network layer protocol.
