The correct answer to this question is D. show rsvp bandwidth is the operational mode command that can help you verify whether the RSVP bandwidth was omitted from the router configuration.
RSVP (Resource Reservation Protocol) is a protocol used in MPLS networks to reserve bandwidth for specific applications or services. RSVP bandwidth determines the amount of bandwidth reserved for an LSP (Label Switched Path) in an MPLS network. If the RSVP bandwidth is not configured correctly, it can lead to issues with network throughput.
The show rsvp bandwidth command provides information about the configured RSVP bandwidth for each LSP on the router. This command shows the actual bandwidth reserved for the LSP, as well as the requested and maximum bandwidth values. If the actual bandwidth reserved is lower than the requested or maximum values, it may indicate that the RSVP bandwidth was not configured correctly.
Option A, show interfaces terse, provides information about the interfaces on the router, but it does not provide any information about RSVP bandwidth.
Option B, show mpls lsp extensive, provides detailed information about the LSPs on the router, but it does not specifically provide information about RSVP bandwidth.
Option C, show rsvp neighbor detail, provides detailed information about RSVP neighbors, but it does not specifically provide information about RSVP bandwidth.
Therefore, the correct answer is D, show rsvp bandwidth, as it provides the most relevant information to verify whether the RSVP bandwidth was omitted from the router configuration.
