Lab Help (please)
 

I want to use the following setup for my ccna lab that is below. The 3550's will be trunked to the 3745. The 3350 will be interconnected via trunking.

Now if i used that setup would i be creating a loop or is that okay. Please give me your opinions. Thanks

Please let me know if i have the below wiring correct.

Sw1 port 24 to Sw2 port 24 (crossover cable) (Trunked 802.1Q)
Sw1 port 23 to R1 fa 0/0 (straight thru cable)
Sw2 port 23 to R2 fa 0/0 (straight thru cable)
R1 fa 0/1 to R2 fa 0/1 using EIGRP or Ospf.
