When attempting to configure a static route on a router in Packet Tracer, I run into an error where the g0/1 interface part of the code isn't accepted. What should I check first, or do to resolve this error message I keep getting? I have been following a tutorial, and doing exactly as the educator does- and this command worked for him, but not for me. This probably means it has something to do with the way Packet Tracer is set up, on my end?
