A. B. C. D.C
The "show isis statistics" command verifies whether the device is sending and receiving IS-IS packets.
The correct command to display the number of IS-IS packets sent and received on a Junos device is option C: "show isis statistics".
The "show isis statistics" command provides detailed statistics on IS-IS protocol activity, including the number of packets sent and received. This command can be useful for troubleshooting and monitoring IS-IS protocol behavior.
Option A: "show isis packets" will display the contents of the most recent IS-IS packets sent and received, but it does not provide statistics on the total number of packets.
Option B: "show isis spf log" displays information about the SPF (Shortest Path First) algorithm, which is used by IS-IS to calculate the shortest path through a network. However, this command does not provide statistics on packet counts.
Option D: "show isis exchanges" displays information about IS-IS adjacency formation and maintenance, but it does not provide statistics on packet counts.
Therefore, the most appropriate command to display the number of IS-IS packets sent and received on a Junos device is "show isis statistics".
