Hey guys. Hope everyone is doing well in these crazy times. I attempted to set up a Router on a Stick setup via instructions on youtube. The instructor did so on packet tracer but I wanted to give it a go on my physical lab. Unfortunately, after completing his tutorial, I cannot ping between the different vlans (each on it's own physical interface on my switch). To clarify, I am trying to set things up as pictured below and as far as I can tell, I have things configured identically. I only have two laptops to use as hosts so I figured if I just plug one int fa0/2 and fa0/3 on the switch, I should be able to ping between both but it won't work. This is not an issue of firewalls blocking pings. It is something in my config but I just don't know what. I made sure to set up trunking and encapsulation. Below the pic is my router and switch configs. Is it possible there are leftover configs on my switch or router that could be mucking up the works? Also, does what is displaying in the show ip route command look correct for router? I don't know why there is mention of /32 subnets when all I have entered at any point has been 255.255.255.0 masks. Thank you fellas!
