So... I have a set up as below. I ping PC7 from the router. obviously an ARP is sent to determine PC7's MAC address. but it doesnt work. i then decide to set packettracer to simulation mode. i ping pc7 again and then. i notice that the switch drops the arp for some reason. I dont get why. someone out there in the world should know why.
notice how it says gigabit ethernet is blocked by STP. It seems i lack in understanding of STP. some wiser being please save me.
since i think its an issue on the switch. here is its running-config
