Hello,
I am very new to networking and Packet tracer, so this issue may be very obvious. But some help would be appreciated!
I am attempting to allow PC-A and PC-C to ping each other. However, I continue to get 'Destination host is unavailable'.
From PC-A I am able to successfully ping R1, and from PC-B I am able to successfully ping R3. So I think there is something wrong in my configuration of R2, or I have missed a step all together.
I've attached configurations of my routers and my topology.
