Thank you for the information. I am stuggling with the use/purpose of VLANs

To me, there is no concept of a layer three VLAN. If you chose to route
IP, you need a router, whether you have dynamic or statically configured
broadcast scopes is fully irrelevant.
l just send a packet to the router which is
on the same VLAN in order for it to be routed.

Just for clarity, VLAN's are a layer 2 concept and IP is of course a
layer 3 (please do not start with the "but what layer is arp again" :)
Despite subnets and VLAN's

A VLAN is, by definition, a separate subnet. If you decided to separate a
single LAN into two VLANs, you'll have to change your addressing scheme.
Once you've done that, you have to route to get from one subnet to the
other. I don't even like the term "VLAN". The very term seems to cause a
