Thank Robin for the remind. I am sending this email to colleagues in the RTGWG to introduce the SAVNET work.
In IETF 113, we held the SAVNET BOF in the INT Area , with a focus on intra-domain and inter-domain source address validation (SAV) technologies. The basic motivation is to overcome the problem of improper block or improper permit in uRPF-based SAV mechanisms. A control-plane solution was presented in the BoF. The basic idea is: 1) each node notifies its attached source prefixes along the real forwarding path, and the routers along the path accordingly build the correct SAV table; 2) the notification messages are processed in the control-plane via a hop-by-hop manner, and various methods are used to reduce the message overhead; 3) following the routing architecture, the notification is divided into an intra-domain part and an inter-domain part. Given that this solution is highly related to routing architecture, after the BoF it was suggested to apply for a WG in the Routing Area. More materials of the BOF can be found from https://datatracker.ietf.org/meeting/113/materials/agenda-113-savnet-01. Enclosed please find the drafted WG charter, which will be improved based on the feedback we get from the community. I also hope that RTGWG colleagues who have interest in this topic can join the SAVNET mailing list (https://www.ietf.org/mailman/listinfo/savnet), which will be the main channel for future discussions.

I suggest you could forward it to the mailing list of RTGWG and briefly introduce the design concept and progress of the SAVNET work. Best Regards, Zhenbin (Robin) From: savnet [mailto:[email protected]] On Behalf Of Dan Li Sent: Thursday, April 28, 2022 4:50 PM To: [email protected] <mailto:[email protected]> Subject: [savnet] SAVNET WG charter Dear colleagues, One month has passed since the SAVNET BOF in IETF 113. In the IESG/IAB meeting, it was concluded that the problem is well-defined and was suggested that SAVNET be moved to the Routing Area. After discussing with the ADs in the Routing Area, we decide to apply for forming a WG with a relatively narrower scope. Specifically, the potential WG will focus on intra-domain and inter-domain SAV mechanisms by extending existing routing protocols. Enclosed please find the drafted WG charter. We would like to get the feedback from our community. Best, Dan
