I've been given a packet tracer file and asked to troubleshoot network issues. Users using workstations A, B and C cannot access files stored on the server. I've gone through some steps such as attempting to ping, checking IP addresses and using tracert. I discovered some issues with IP addressing and incorrect WAN interface settings and fixed them. I'm not sure what is continuing to make things unable to ping each other and what makes the PCs unable to acquire a DHCP address from R1. I've posted the packet tracer file and troubleshooting steps I took attached as files below. I also copy and pasted my troubleshooting steps below in the spoiler.
I assume that the network IP addressing scheme is identical to the one in Pro2of3. I am not sure from which PC she is trying to access the files on, which I imagine must be on the ‘Server’. I will first attempt to ping from PCs A B and C to the server to test connectivity and if they fail to attempt a tracert to narrow down where the issue might be happening.
PC-A cannot ping to the server and cannot make a single hop:
PC-B cannot ping to the server and cannot make a single hop:
PC-C cannot ping to the server. Tracert indicates that it can reach R2’s f0/0 interface (10.0.30.1) but not R1’s s0/1/0 interface (10.0.50.1).
Attempting to telnet to the server from any PC results in “Connection timed out; remote host not responding”
This indicates that the issue may exist from lvl 4 Transport layer downwards. We will use a top-down approach to troubleshooting starting from layer 4.
I will check all IP addresses on interfaces and SVIs to make sure they are correctly addressed and also check that any ports that are meant to be online are online.
Configured DHCP on R1 with the following commands:
The working .pkt doesn’t have this ip route part. It also has ripv2 configured.
