FSv1 found problems with undefined interactions between actions encoded as Extended Communities.
FSv2 (draft-ietf-idr-flowspec-v2-03) allows for ordered actions using Wide Community.
Some implementers desired both Extended-Community Actions with specific default order and defined interactions. A new Extended-Community will be expanded for FSv2.
Other implementers want to be able to specify an order for actions. The user specification of action ordering will not fit in the Extended Community, and so the Wide Community format (type 2, FSv2 actions) will be used.
One key issues with Ordering of Actions is the action taken when an action does not successfully complete. Potential recovery from a failed action are: ignore, continue, halt, roll-back.
