I have a couple of questions about this network.
This is a part of configuration finishing with the error that stopped me.

I tried to make two subinterfaces on each interface of the router, one for vlan10, one for vlan 20.
1. If that is not possible, should I make subinterfaces on fa0/1 of L3, and make a new connection between router and L3 switch?
2. I configured as trunk ports: fa0/24 of S1, fa0/24 of L3, fa0/24 of S3. Is that right? What about fa0/1 of S3 and fa0/24 of S4?
3. The given IP range was 192.168.0.0/23, so I made vlan10 192.168.0.0/24 and vlan20 192.168.1.0/24, cause I needed classfull network for ripv1 routing. Was that right?
I attached picture and packet tracer file. If I forgot to explain or mention something, ask me. Any help would be great, but be sure to explain it to me like I'm an idiot cause I'm new to this. This was an exam problem.
