Hello Vittawat
Yes that is correct. In the specific topology, R2 would essentially function as a switch so any broadcasts sent on Fa0/0 of R1 would reach the Fa0/0 interface of R3.
Now as for your question about limiting broadcast storms, for a topology similar to that in the lesson, a broadcast storm would not be a possibility. This is because there are only two hosts in the link, R1 and R3. A broadcast storm is a concern only when there are tens or even hundreds of devices within the same broadcast domain. Typically when you configure a router to function as a layer two bridge, you wouldn’t connect it to a LAN with many devices, but it would most likely be a point to point connection, so no storm control configurations need be implemented.
I hope this has been helpful!
