Currently learning about networking and layer 3 switches and routers.. I don't understand when you decide to use layer 3 switches opposed to routers and vice versa. Although I've read switches are supposedly better at handling vlan's in terms of performance compared to router on a stick, so I guess that is a deciding factor.
But if this is the case, then technically you can get away with not having any routers because layer 3 switches can link to the firewall? Unless you are using the router given by the ISP?
So a network could look like: ISP > Firewall > Layer 3 switch > access (layer 2) switches ?
However I have seen some network designs go with ISP > Firewall > Router > Layer 3 switches > layer 2 switches... But what would the need be for the router?
