You have configured an IP-IP tunnel between Router A and Router B
Which Junos operational mode command is used to verify that the tunnel interface is up and operational?

A. B. C. D.C
The correct Junos operational mode command to verify that the IP-IP tunnel interface is up and operational between Router A and Router B is "show interfaces terse" or "show interfaces tunnel".
Option A, "show chassis tunnel status" displays the status of tunnels that are created using GRE, IP-IP, or IPIP tunneling, but it does not provide information on the specific IP-IP tunnel that has been configured between Router A and Router B.
Option B, "show tunnel interface" is not a valid operational mode command in Junos.
Option C, "show interfaces terse" is a valid operational mode command that displays a summary of all interfaces on the router, including the IP-IP tunnel interface. The output will show the interface name, status, and protocol information, which will indicate if the tunnel is up and operational.
Option D, "show interfaces tunnel" is also a valid operational mode command that displays information about all tunnel interfaces configured on the router. This command will provide more detailed information about the IP-IP tunnel interface, including the local and remote IP addresses, the tunnel type, and the tunnel state.
Therefore, both options C and D can be used to verify the status of the IP-IP tunnel interface between Router A and Router B.
