we have summit x460 configured with 3 vlans. ipforwarding is disabled to all vlans but were still able to ping from one vlan to another. please see below the screenshot
we also have pc directly connected to vlan server and still can reached the other vlans even the ipforwarding is disabled. below is the screenshot
below are the iproutes from switch
is this correct? I am expecting if ipforwarding is disable vlan will not communicate with each other like layer 2.
