I am totally new to security, I have an idea of BGP. Now looking into security to mitigate DDOS. So I did a quick reading and found out that BGP flowspec does that work of DDOS mitigation, but i did not find anything regarding openbgpd. So i thought we might have to additionally use some tecniques on top of openbgpd/openbsd. So i came accross Exabgp, now I am wondering if it can be used with openbsd/openbgpd ?
