Note: Hard loopback tests are intrusive and will impact service. In a hard loopback, a special loopback plug is used in order to loop the traffic from the T1 port back into the T1 port. This figure illustrates the setup for hard loopback.
If you want to use ip ospf network point-to-point with your loopbacks, you must be sure to put them into unique IP networks (which they should be in, anyway), say: 172.16.101.1/24 for R1, 172.16.102.1/24 for R2, 172.16.103.1/24 for R3, and 172.16.104.1/24 for R4.
