Which of the following about the routing table on an Nokia 7750 SR is FALSE?

The statement that the routing table is used in the MPLS data plane is inaccurate. The routing table primarily serves control plane functions, while the data plane is responsible for actual packet forwarding based on the information provided by the control plane.

Specifically, the routing table, maintained by the Central Processing Module (CPM), holds critical information such as the next-hop information that is essential for routing decisions. This information is used to construct the forwarding table, which the data plane utilizes to efficiently forward packets. In an MPLS context, the MPLS forwarding table is derived from the routing table, but it operates based on labels rather than traditional IP address-based routing. As such, the MPLS data plane doesn't directly reference the routing table for its operations; instead, it utilizes the label-forwarding entries associated with MPLS.

Therefore, while the routing table plays a pivotal role in overall network routing decisions and management, its direct involvement in the MPLS data plane as described in the false statement is not accurate.
