Hi Sarath,
Yes , we need to use below command to add license.
> request system license add terminal
Paste the license key and press Enter to continue.
No down time / no reboot required/ no configuration required, you need to add license to each node separately.
You can update license via below command as well if you got internet connection from the routing engine.
>request system license update
Ensure that both nodes get updated license.
