Wei, Aijun, et al,

I forget to include the questions about draft at my last support message:

1.       Page 3 says:

 if the "trashing routes" come from the interested VRF, filter on RTs will erase all prefixes from this VRF.



why erase all prefixes even if the “trashing routes” only contain a subset of prefixes for the VRF?
 [WW] RTC aims to tell the peer "I want to receive VPN routes with RTx", if the offending routes carry RTx, RTC can't tell the peer to stop sending these routes unless withdraw the entry with RTx.
How about the following updated sentence?
"RTC can only filter the VPN routes from the uninterested VRFs, if the "offending routes" come from the interested VRF, RFC mechanism can't filter them."
[Linda] that is much better.


2.       Is the ORF message sent to all peers? Or just a selective peers?

“each of them makes a local judgement to determine whether it needs to send VPN Prefix ORF to its peers.”

[WW] Thanks for pointing out this typo, it should be changed to "each of them makes a local judgement to determine whether it needs to send VPN Prefix ORF to its upstream peer."

[Linda] For iBGP with RR distributing the UDPATE, how does the BGP speaker know who is its upstream peer?


NITs:

Past 6: (you need to do a global change.)

past --> passed:

When routes associated with <RD31, PE3> tuple past the quota but the prefix limit of VPN1 VRF is not exceeded,

[WW] Thanks, will correct this typo in next update.

Hi Everyone,

    I read the draft and all the discussion on the mailing list. I think adopting to WG draft can further  improve the draft with more WG  discussions. Therefore I support its adoption.

Best Regards,
Linda

This begins a 2 week WG Adoption call for draft-wang-idr-vpn-prefix-orf-03.txt

https://datatracker.ietf.org/doc/draft-wang-idr-vpn-prefix-orf/<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdatatracker.ietf.org%2Fdoc%2Fdraft-wang-idr-vpn-prefix-orf%2F&data=05%7C01%7Clinda.dunbar%40futurewei.com%7Ca7c4d04312174fd5662908da858144db%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C1%7C637969087510439673%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000%7C%7C%7C&sdata=ZR9uO%2FOTWaDjW3xA9Za6QRTsZXKXx4%2FgLyCAeIfxEjI%3D&reserved=0>



The authors believe that they have addressed the concerns raised in

the previous 2 WG adoption calls.



The WG should consider if:



1) The revised text answers the previous concerns regarding

the scope of this draft?



2) Does the revised text provide a useful function for

networks?



3) Are there any additional concerns regarding the new text?



Each of the authors should send an IPR statement for

this version of the draft.



The adoption call was moved to 8/29 to 8/30 to allow questions

to be asked at the IDR interim meeting on 8/29/2022 (10am - 12pm EDT).



Cheers, Sue Hares
