Packet Tracer Exploration: Routing Table Corruption 7.4.3.2

This network topology consists of 5 routers. One router at the very top named R2, which is connected to a serial leading to another router named R1. R2 also connects to another router (R3) via crossover cable. R3 and R1 are also connected by a crossover cable. R1 is connected to another router named ISP. There is one other router named R4 that is not connected to anything. First I turned up the interfaces by issuing the no shutdown command in each interface. I examined the routing table on R1. Afterwards, I configured router rip for each router. with the network 172.16.0.0. I then began to configure static routing from the ISP router using the commands:

ip route 172.16.1.0 255.255.255.255.0 s0/0/0
ip route 172.16.2.0 255.255.255.255.0 s0/0/0
ip route 172.16.3.0 255.255.255.255.0 s0/0/0
ip route 172.16.5.0 255.255.255.255.0 s0/0/0

I then connected the Fa0/0 interface on R4 directly to the fa1/0 interface of R3.
Afterwards, I checked the routing table on R4, and everything looked fine and up and running.
