Hello all. I was using packet tracer to build a simple network to test my subnetting abilities, and I believe I have everything subnetted correctly, however I cannot seem to get information to travel to the other network. I didnt set up anything security wise on these as it was practice for subnetting only, so I just wanted to make sure there was communication, but I can ping everything within the local network, however as soon as it tries to go out to the other router, it fails. Destination host unreachable. I watched the simulation but couldnt figure out why it wouldnt send it on. I havent had to do static routes in class yet, even though we have briefly discussed them, and we have discussed OSPF but I havent had to configure that either.
If its one of those two, my only guess as to why I havent seen this yet is because they already have that set in the Packet Tracer activities they have us do. Here are my maps. I couldnt attach my pkt file.

Attach the zipped pkt file and we can take a look.
"Destination host unreachable" you dont route on the routers.

Hello,
Please see my solution below as it fixed your issue when I applied it to your packet tracer file. You could also do the same with EIGRP but I used OSPF since you said you talked about it.
Config t
router ospf 1
network 0.0.0.0 255.255.255.255 area 0
no auto-summary

Hello,
Subnetting aside you will need to make sure both routers know how to get to the respective remote subnets either with static routes or a routing protocol.
Easiest way is probably this on both routers:
Config t
router ospf 1
network 0.0.0.0 255.255.255.255 area 0
no auto-summary
This assuming all interfaces on both routers cover all the subnets you want to reach.
