What are my choices for VLAN handling (diagram attached)

[mobiuscog]

Thanks for the reply.

I realise that handling the routing at the router is easier, but it also means extra hops being made that don’t need to be and research leads me to believe that I should be able to perform inter-vlan routing at the switch, but still at wire-speed on some switches.

@brwainer

Choosing between the router and the layer 3 switch doesn’t have to be all or nothing, you can have some VLANs use one as the gateway and some VLANs use the other, as long as you also set up the static routes between the router and Layer 3 switch properly (the router needs to know about the subnets which the L3 switch is the gateway of, and vice versa)

This is where I find things aren’t as clear - can I set a L3 switch to be a gateway and still have wire-speed throughput ?

All I’m trying to do is keep the speed as maximised as possible whilst also avoid having all routes go via the main router if it’s not needed. The other switches would probably just be 802.11Q capable, perhaps with port-isolation, but nothing beyond that. I’m just trying to figure out my best choices for the ??? box without causing any slowdowns.
