I am working on an assignment and I am stuck. I connected 3 routers, 3 switches, 4 computers, and a server. I have created 2 vlans which router 2 and switch 2 use. I can ping between the computers and the internet but not server 3 which is connected to router 3. I am trying to ping server 1 from PC1 but receive a "timed out" response every time. The connections (serial DCE) are as follows: router 1 s0/1/0 is connected to router 2 s0/1/1, router 2 s0/1/0 is connected to router 3 s0/1/1, and router 3 s/0/1/0 is connected to router 1 s01/1. All of the serial connections are using a 255.244.244.252 subnet which allows for 2 hosts. I tried to set up a default route according to the instructions. For instance, router 1's s0/1/0 points to router 2 s0/1/1 at 0000.0000.0000.0000 0000.0000.0000.0000 172.16.68.2 and I thought I had done so correctly for the other two routers but I just receive the "timed out" error when pinging the server from any of the computers. I have to have the equipment set up the way it is, I cannot alter it in any way per the instructions. Could someone please take a look at the packet tracer file that I have uploaded (zip file)? Also, I have uploaded an image of the snippet of the instructions specifying how you are supposed to get packets to travel between all three routers. I have tried to follow the IP address pattern specified in the instructions and it still failed to ping the server. I received a "timed out" error. If I deviate from the pattern I end up receiving a "destination host unreachable" when trying to ping the server from PC1 (or any of the PCs).
