I want to know if I'm protected for ARP spoofing.
In my network, all PCs, printers, phones and servers are in distinct VLANs. I got a layer 3 switch for servers, which handles routing between these VLANs, and layer 2 switches for connecting PCs, printers and phones. I use DHCP snooping to be sure that only my DHCP server is giving IP addresses. I have an internet gateway in the same VLAN used for servers. I don't have any specific configuration for ARP on the layer 2 and 3 switches.
Since ARP is blocked by routers, am I open or not to ARP spoofing?
