IPv4 and IPv6 inter-VLAN communication at the same time

[AntonioNeto]

Hello,

I started a project in Packet Tracer recently while studying some IPv6 and IPv4 concepts, and I've come across this situation.

I currently have 4 IPv4 subnets and 4 IPv6 subnets, where each one is assigned to a different PC (PCs have both an IPv4 address and IPv6 address assigned to them). I also assigned each pc to different VLANs (lets say 10, 20, 30, 40). 

Can I enable inter-VLAN communication on the router for both IPv4 and IPv6? This meaning I would assign both an IPv4 and IPv6 address on the router's sub-interface for each VLAN. I've seen people configuring either only IPv4 inter-VLAN communication or only IPv6 inter-VLAN communication, so that is why I've resorted to asking this here.

I hope my question isn't "silly" or anything, and I appreciate any help

Yes.

This is exactly how you need to do it.

"Can I enable inter-VLAN communication on the router for both IPv4 and IPv6?"

Yes, as already noted by Harold, he and you also detailing how to do it.

Just wanted to add, although IPv4 and IPv6 can share an interface and/or a VLAN, they (IPv4 vis-à-vis IPv6) do not (directly) intercommunicate with each other.
