The correct answer to the question is D. show rsvp session detail.
In Resource Reservation Protocol (RSVP), Refresh Reduction is a mechanism that reduces the number of refresh messages exchanged between RSVP nodes to improve network performance. In this mechanism, a node sending a Path message to reserve resources for a particular traffic flow specifies a "refresh interval" for the reservation. This refresh interval indicates how frequently the node sending the Path message will send a Refresh message to the nodes along the path to keep the reservation alive.
To verify whether the Junos devices in the network are operating correctly in Refresh Reduction mode, the "show rsvp session detail" command can be used. This command displays detailed information about the RSVP sessions, including the refresh interval specified in the Path message, the refresh messages sent and received, and the current state of the session.
The other options provided in the question are not relevant to viewing the refresh messages sent and received. The "show rsvp interface" command displays information about the interfaces configured for RSVP, such as their status, bandwidth, and link-layer protocol. The "show rsvp version" command displays the software version of RSVP running on the device. The "show rsvp neighbor detail" command displays information about the RSVP neighbors, including their addresses, state, and capabilities.
Therefore, the correct command to view the refresh messages sent and received is "show rsvp session detail."
