Ok so my background is not networking but I'm trying to better understand.
Let's assume we have a simple layer 3 switch. SVIs can be used to route traffic between vlans.
If I want to add a firewall between these vlans, can this only be achieved by essentially moving this routing to the firewall and removing the svi?
I guess what I'm trying to understand is that are SVIs only generally used when vlans don't need any specific security around them i.e, if you don't have any specific need to restrict traffic between vlans, then using an svi is fine via the l3 switch
