Hello Lucas,
Please note the command options from the command reference guide:
Follow these guidelines when you specify the output interface or the next hop address of the static
route:
• If the output interface is a Null 0 interface, no next hop address is required.
• If the output interface is a point-to-point interface, you can specify only the output interface. You
do not need to change the configuration of the route even if the peer address is changed.
• NBMA or P2MP interfaces need IP address-to-link layer address mappings for successful
packet delivery. As a best practice, specify the next hop address for the route at the same time
if the output interface is an NBMA or P2MP interface.
• If the output interface is a broadcast interface, the device uses the next hop IP address to obtain
the MAC address of the next hop. Therefore, you must specify both the output interface and
next hop IP address in most cases.
Hope this helps!
