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

is this correct? I am expecting if ipforwarding is disable vlan will not communicate with each other like layer 2.

thanks

Hi Marlon, do you still need assistance with this? It may be best to open a case with GTAC if this hasn't been resolved yet.

I think so too, but I wanted to try to be sure. Lots of loose ends around here that I'm trying to tie up 🙂

in my opinion Matthew gave the answer on that topic.
