Hi...trying to figure out why there would be the need to configure router on a stick using a L3 switch (meaning, the L3 switch is acting as the router), instead of just creating routed SVIs and enabling dot1Q trunking on the port and being done with it...Router on a stick was used on legacy routers that didnt support vlans and had limited interfaces...

Hi Visitor68,
I agree, You don't need router in a stick scheme if you have a L3 switch, if you want to enable intervlan routing you just execute: ip routing command line globally and also you can create the interface vlan (SVI).

The only purpose I could see for retaining a router-on-a-stick would be if the router has some features you require that are just not available on a L3 switch.
This, I would expect this would be an unusual requirement even though real/pure routers often have features not available on a L3 switch, as those/such features are also often not needed for LAN routing.

Thanks, Julio. I did find out what was behind my client's thinking: he wanted to avoid running STP instances for SVIs.

You are welcome,
mmm disable STP is not a good idea, now if he wants to keep a just 1 instance for all the VLANs, he could implement MST.
