great work josh. thanks a lot

This tutorial works perfect. Initially pings were failing to each other. i stopped and started the switch. after that pings are successful.

Thanks for getting back. Turns out I didn’t do a no shutdown command on an interface.
I apologize for the bother.

Thanks though!

Brian,

I know you have probably done this already but can you make sure you created vlans on the router?
