Using background information, I was tasked with creating appropriate subnets and configuring the connected sub-networks in Cisco's network simulation tool, packet tracer. This involved assigning appropriate IP addresses to each device (and router interfaces) on each section of the network and testing their connectivity.

in this lab, I had an error where I mistyped a subnet as 255.255.255.248 instead of 255.255.248.0. If general troubleshooting doesn't help, it would be helpful to go through and look for possible small inconsistencies.

• Config > RIP
• CLI > type "version 2"
• Config > add network (e.g. 172.16.0.0)

• Remove 172.16.0.0 from RIP
• Run the command "version 2"
• Add network (e.g. 172.16.0.0) back to RIP
• Save the config to NVRAM
• Reboot the router

Note, I changed "Engineering Last to Sales Last" PDU to Sales Last to Engineering Last since the last device on the engineering network was not equipped with a CLI.

The packet tracer portion of the lab was very useful to apply my learned subnetting knowledge into a simulated example. In the future, I want to remember to pay very close attention to detail when manually typing in IP addresses and subnets as it is very difficult to go back through each one to find the mistake(s).
