Router Set up

---

Now, this is just to prevent some troubleshooting in the future for myself. As a tip of advice before testing the packet tracer file, be sure everything and I mean EVERYTHING is properly set up. Make sure the needed attachments for Serial ports or the third Ethernet port are added before trying to connect and send PDU packets through the network. Along with that make sure that the network address is inputted into the RIP routing configuration along with making sure it is updated to version 2. There are detailed instructions on how to do these sets in the previous lab responses.

Subnet Cheat Sheet

The last address of a subnet is always the broadcast, not just .255. So the last usable address is always the broadcast(actually last) address minus one. The first usable address of a network always goes to the router and thus acts as the default gateway of the connected devices. So a connected device using the first usable address it can get is always the first usable address +1. Speaking of default gateways, remember to set that up on each connected device, or else packets/PDU will never be able to get to other subnets.
