Destination host unreachable

[rascal123]

I am having trouble when I try to ping a pc from one router to another. For example PC0 to PC2 it gives me the "Destination host is unreachable" error and doesnt send the ping. However when I try to ping a pc on the same router, for example PC0 to PC1 it pings just fine, this leads me to believe there is a problem with the router 3 setup? Im not sure, any help would be appreciated! I tried to include my packet tracer file but its not an accepted format, so here is a picture of it. Thanks

Hi @rascal123 

A router can route packets (such as ping) from networks that are directly connected.
On the other hand, for remote networks, a router must have a route indicated for that network.

Routes to networks can be verified using the command Router # show ip route 

To tell a router the route to remote networks, you can use static routes or routing protocols.

You can search manuals for these points on the internet, there are many available.

Thanks for the reply however is there anything wrong with how I setup the network, such as IP addresses or subnet masks such that I dont have to use routing protocols or static routes to fix it?

Hi @rascal123 

From what I see in the image you attached, the address looks ok.
Now, even if your address is ok, if a router does not know the route to reach a remote network, that router can never communicate with that remote network.

That is why it is necessary to indicate to the router a route to those remote networks, either by static routes or routing protocols.

Obviously, if the networks are connected to the same router, you will have successful connectivity.
