Destination Host Unreachable

[BryceCrawford]

Good day, My teacher gave me an assignment to connect a PC to another PC, but every time I try to ping, it always says destination host unreachable. What steps have I possibly missed?

And also, please give me advices if you have any!

 For your topology, the best way to ensure connectivity among all PCs is enable dynamic routing protocol. You can use RIP which is the simplest protocol.

On the router, you run

router rip

version 2

netwrok x.x.x.x 

The network statement must match with the IP address configured on the router´s interfaces. For example, if the interface have IP address of 192,.168.1.1 you use the network 192.168.1.0 on the RIP´s network command. 

You can also zip your PacketTracer file and attach here for further help

Hello, thank you for replying!

I'm pretty sure I have RIP set up but I still haven't managed to ping every computer. However, I have created an excel so you can see it better!

 You can not use the same IP address in both routers. Each interface must have its own IP address

you dont need to advertise all the hetwork in all router. You only advertise the network that is direct connect to the router

Here is a working file

Hello @BryceCrawford 

Take care about your RIP configuration on all routers.

On each router, on the RIP process, configure the network statement with the subnet connected to that router! Example for Router 1:

Also, take care about IP configuration on serial interfaces _ same IP on s0/0/1 in Router 1 and Router 4:

Afater modify the IP address on Router1 interface s0/0/1 as 10.27.9.10/32 you should ping Router4 s0/0/1 (10.27.9.9) and after modify RIP process as I said Router1 learn the subnet 192.168.27.0/24 frome Router4:
