Hi Sue, IDR WG,

I agree with Jim Uttaro with respect to the use case being weak and already solved with other mechanisms.

Also, there was much opposition to changing the RD semantics and using it for route filtering. See:

https://mailarchive.ietf.org/arch/browse/idr/?q=%22wang-idr-rd-orf%22

I don’t see that this has changed and, additionally, this will add further complexity to BGP route filtering dynamics.
Thanks,
Acee

This begins a 2 week WG adoption call for draft-wang-idr-rd-orf-05.txt (from 2/4/2021 to 2/18/2021)

This draft defines a new Outbound Route Filter (ORF) type, called the
Route Distinguisher ORF (RD-ORF).  RD-ORF is applicable when the
routers do not exchange VPN routing information directly (e.g.
routers in single-domain connect via Route Reflector, or routers in
Option B/Option AB/Option C cross-domain scenario).

Please be aware that this draft has one IPR statement attached.

https://datatracker.ietf.org/ipr/4579/..

Please consider the following questions in your review and comments:

1) Will this new ORF filter reduce routing information at key points?
2) Should the WG consider this draft given it has an IPR claim or
    Would the IDR WG prefer another approach?
3) Is this draft ready to be adopted and refined as WG draft?

Cheerily, Susan Hares
