(While Justin and others chime in)

We are relying on :

https://github.com/esnet/dumbno (this one has IPv6 support) Originally
we started with Justin's branch here: https://github.com/ncsa/dumbno

On bro side there is a conn-bulk.bro and react framework 

Here: https://github.com/JustinAzoff/bro-react

This ties bro with dumbno.py which talks with arista to apply and remove

If you need specific arista configurations, I can send you our arista configs
