Cisco Packet Tracer Issues

[29Terqlmn]

2 Router 2 Switch 2 PC config.

PC A AND B -> R1 OK

PC A > B OK

R1 -> R2 OK

R1 -> Lo0 OK

I'm guessing its an issue with the route table. Any help appreciated.

Here are the router configs

hostname r1

Old thread, but still gonna answer.

Based on what I could see, it is the ip route on the second router that is the problem. On the first router, it is sending everything through interface Serial2/0 but on the second router, it is sending everything to Loopback0. Which means that Router2 cannot get to Router1
