Hi WG,

After reading the document, I think it is useful to distribute routing policy in BGP, and I think it is ready for WG adoption.

Well,  I have some comments and questions:

0.  Section 3, Problem statement, may add more text to specify

1.In #section-3.1<https://tools.ietf.org/html/draft-li-idr-flowspec-rpd-05#section-3.1> and 3.2, P node should be illustrated in the figure, I do not find it in the figure. Also, it is a little bit hard for me to get what is inbound and outbound from the figure. May add more text to clarify?

2. Section 4.1,

Distinguisher:  4 octet value, it should be 4 octets or 4-octet?

3. Section 4.1, may add reference to 0?

When receiving a BGP UPDATE message, a BGP speaker processes it only

   if the peer IP address in the NLRI is the IP address of the BGP

   speaker or 0.

Best Regards,

The WG Adoption call for daft-li-idr-flowspec-rpd-05.txt need additional support for adoption.   I encourage the authors to make sure those wishing to make comments on this draft to do so over the weekend.

This draft deploys the passing of BGP policy in a new AFI/SAFI and Wide communities.   At this point, my understanding from the email is that mechanisms eases the configuration burden in some networks.

Are there any operators who are concerned that this mechanism (AFI/SAFI + Wide Communities), contains information that will leak into their network by accident?   Or will the AFI/SAFI + WIDE communities provide a clear delineation between a group of networks who support this feature and those who do not.

Thank you, Sue Hares
