Say you have a L3 switch routing between VLANs 10, 20, and 30, and you need to uplink the switch to a router for the VLANs to get to the rest of the network. The VLANs don't traverse between sites. I know if you had a Cisco switch you would do
no switchport on the switch port that connects to the router, essentially making a routed interface. The switches I'm using don't have that option, so I figured I would create an access port on the switch assigned to its own VLAN 100 with a virtual routing interface. I figured this would kind of keep the traffic on the uplink limited to traffic coming in and out of the branch and free from what's bouncing around between VLANs 10, 20, and 30.
Does this make sense? Is there a name for this? Or is there a better practice?
