Both are good points. Regards, Jakob. From: Idr <idr-bounces@ietf.org> On Behalf Of Robert Raszuk Sent: Thursday, January 3, 2019 3:03 AM To: idr@ietf. org <idr@ietf.org> Subject: Re: [Idr] I-D Action: draft-ietf-idr-flowspec-l2vpn-09.txt Hi, Two observations: 1. The current draft extends exisiting SAFI 134 with new NLRI types. That means that now we have new giant NLRI in SAFI 134. Have any consideration been made to just define a new flow spec SAFI instead for L2 filtering ? I am quite skeptical from implementation, operational and deployment points of view to extend the existing SAFI and it makes a gradual deployment a nightmare if not mission impossible. Any change to NLRI format without signalling it with new capability is far from good practice. 2. The draft is pretty silent on adjusting validation procedures to make sure only senders of the original L2 information may inject the L2 flow routes.. I would hope that this is basic omission and will be consider for addition into next version of he draft. Thx, R.
