You may want to examine the IDR lsit archive https://mailarchive.ietf.org/arch/browse/idr/?q=orf for discussion of the orf proposal and the difficulties people have with it. Yours, Joel On 8/18/2021 1:10 PM, Douglas Fischer wrote:
Hello!
I also found a recent draft(expires Novembre 2021) about using Route Distinguisher as a Value on ORF. https://datatracker.ietf.org/doc/draft-wang-idr-rd-orf/ <https://datatracker.ietf.org/doc/draft-wang-idr-rd-orf/>

Hi,
Is anyone aware of any vendor that supports Outbound Route Filtering (ORF) based on anything other than prefix-lists?
I found these two old IETF drafts (both expired :-/) which supported the idea of filtering based on community and as-path respectively, but I wasn't able to understand if they were ever discussed at the WG and if there was any outcome of the discussion (I suspect the authors are no longer even working with the mentioned companies in the drafts):
- https://datatracker.ietf.org/doc/html/draft-chen-bgp-ext-community-orf-02 <https://datatracker.ietf.org/doc/html/draft-chen-bgp-ext-community-orf-02> - https://datatracker.ietf.org/doc/html/draft-ietf-idr-aspath-orf-13 <https://datatracker.ietf.org/doc/html/draft-ietf-idr-aspath-orf-13>
Any info is very much appreciated.
Thanks,
