Flowspec (Custom)
🚧Prior to creating a Flowspec plugin, you will need to configure at least 1 device with a unicast BGP neighbor.
Flowspec (Custom) differs from Flowspec in that it allows for a custom rule to be added. Rules are written in the flowspec token language, e.g. match destination DSTIP then discard
