In your RSVP network you have configured three separate LSPs to the same egress address. You have made no other configuration changes to the forwarding decisions made by the router. Which commands can you use to determine which LSP is being used to forward packets?

A. B. C. D.A
In an RSVP (Resource Reservation Protocol) network, multiple LSPs (Label Switched Paths) can be configured to the same egress address. Each LSP can have different characteristics and priorities that affect forwarding decisions made by the router. In this scenario, we want to determine which LSP is being used to forward packets.
The correct command to use in this case is option D, "show rsvp session." This command displays information about the RSVP sessions and the LSPs that are associated with them. It provides details about the RSVP sessions that are currently active, including the source and destination addresses, the LSPs that are being used, and the traffic that is being sent.
Option A, "show route table inet.3," displays the IP routing table for RSVP traffic. This command shows the routes for the RSVP protocol in the inet.3 routing table. However, it does not provide information about the LSPs that are being used.
Option B, "show route table inet.4," displays the MPLS forwarding table for RSVP traffic. This command shows the routes for the RSVP protocol in the inet.4 routing table. However, it does not provide information about the LSPs that are being used.
Option C, "show rsvp neighbor," displays information about the RSVP neighbors that are connected to the router. This command provides details about the RSVP neighbors, including their IP addresses and their RSVP capabilities. However, it does not provide information about the LSPs that are being used.
Therefore, the correct command to use to determine which LSP is being used to forward packets in this scenario is "show rsvp session." This command displays the details about the active RSVP sessions and the LSPs that are associated with them.
