I have this graph:
I managed to make PC1A ping PC2A, they are in the same network but I have to make PC1A ping PC1B and I can't.
I did this:
Why I can not ping them? What kind of routing should I use?

You will need to build static routes in the various routers... what are the WAN interface IP's of the various routers? and what make/model routers (some don't do static routes very well)?– acejavelinMay 20, 2018 at 17:23

I am not sure if I can answer your question. All I know is that I have to use either default, host or network route. For example, "route add 172.16.1.1 gw 192.168.1.254"(host route)– Ангел ХаджиевMay 20, 2018 at 17:40

No, you need to add the subnet... For example, in AC there would need to be a route like "route 172.16.1.0/24 via gw 192.168.1.254" (the exact command may vary) but basically you need to tell the router the subnet is reachable via router AC's WAN (eth1) IP address, and you need a route in reverse in BC. And this is just to talk to the other subnet, you would need a rule for each subnet and a default gateway. Again, this process varies and you are not giving sufficient information to formulate an answer.– acejavelinMay 20, 2018 at 17:45

Not sure if the route table will make it more clear prntscr.com/jkbi3o– Ангел ХаджиевMay 20, 2018 at 17:52

So you are trying to control the routing at the PC level? Than you need a route back from PC1A. Sorry, I am getting more confused... What are the .254 addresses? You have a 172.16.1.254 defined as a the default gateway in PC1B, but your network diagram does not show that IP anywhere. Again, your network diagram is missing critical information, specifically the IP addresses of the various interfaces on each router.– acejavelinMay 20, 2018 at 17:58
