I need help. I'm new and have been practicing Cisco routing on Cisco Packet Tracer and made a topology (Static) but it seems that I can't ping from PC1 to PC3, vice versa. I can ping PC1 to PC2 and PC3 to PC2 but when I ping from PC1 to PC3 or PC3 to PC1, Request Timed Out shows.
Here's the ip route I made from each router.
R1:
ip route 192.168.20.0 255.255.255.0 200.0.0.2
R2:
ip route 192.168.10.0 255.255.255.0 200.0.0.1
ip route 192.168.30.0 255.255.255.0 200.0.1.2
R3:
ip route 192.168.20.0 255.255.255.0 200.0.1.1
Attached is my .pkt topology.
