I would like to know if it is possible to record and compare the differences in route tables over time for any router on our WAN. We use BGP so not sure if that makes any differnce as it should be just a show command and output of text from the CLI.
I want to have a way to look back to see what changed on the device config (if at all) and the state of the live RIB vs the last saved/benchmarked RIB.
If any of this is even possible could it be done as part of a scheduled task and some sort of alert to notify that something has changed?
Thanks in advance.
