Hello, I am fairly unfamiliar with packet tracer and I am having an issue with my file. I can get my routers to ping end to end except for my Site 2 Router (as seen in the file). This router is the only one that doesn't ping end to end as it doesn't ping to Datacenter Routers 2, 3, and 4. I also have the issue of my PCs not being able to ping end to end as I need them to so I can implement network security features. I also have no idea what my default gateway would be either. I've attached a picture of my network for reference in order to help with debugging possibly.
- Help with pinging Routers end to end.
- Help finding default gateway.
- Help with pinging PCs end to end.
**EDIT 4-9-21 8:38AM:
I got within sites to work (Site 1 PC1 pings to Site 1 PC2), but it doesn't ping end to end (Site 1 PC to Site 4 PC, etc.). I also have now uncovered an issue with my Site 2 router where it is the only router that doesn't ping end-to-end. How would I fix these problems?
- PC end-to-end ping.
- Site 2 router end-to-end ping.

Hello,
don't be scared, but every single device in your network is misconfigured. What are the IP address requirements of your topology ?
Is there a text file that describes what you are suposed to do ?

Hello,
attached the reworked file with end to end connectivity. As stated, each single device was misconfigured. Compare your original file with the one I sent. The most important things are:
--> PCs need to have the proper default gateway
--> the layer 2 switches can have only one active Vlan interface, for management
--> you cannot have duplicate subnets on different routers

My initial look, in case of Ping site 1 to site 2, several routers do not have route to 172.69.41.40, i.e Site 2 router and Datacenter routers. maybe some issues with ospf as some configs appear to be in wrong places (no ip address but ip ospf 1 area 0)
this will require more time and coffee ....

after fixing ospf (hint in my previous post), DC router 1 must have ARP clear, so there is something else wrong. One of servers has wrong IP address.
