Automated Check to check OSPF links are share the same network/mask, area and timers. Be aware that as CDP is used you will see the mismatch from both traffic directions ie: it will show a failure from R1 to R2, as well as R2 back to R1. This is the same mismatch shown from both perspectives of each device.
This script used CDP was designed to be used on directly links. Switched shared segments will break the CDP logic.
This script uses Nornir2, not Nornir3. Install with:
pip3 install nornir"<3"
This script was tested using CSR1000v Images (Cisco IOS XE Software, Version 16.11.01b)
