I was looking to play around with some BGP changes so I set up a topology in GNS3 using FRR docker containers. Once I laid out the topology I didn’t want to manually address it, so I automated the entire lifecycle. Address generation, config application etc.
This ended up taking way longer than manually doing it but was also way more fun and is now much easier to reset!
BTW: FRR docker containers are incredible if you’re just looking to lab routing protocols. Even running a whole bunch of them the GNS3 VM barely skips a beat.
