Robert,

I had previously alluded to your point:  "Further, I think the idea of statically configuring per [VPN, PE] state on every PE in a VPN is a failed IQ test."

Yours Irrespectively,

John

[External Email. Be cautious of content]

Wei,

I just want to highlight one important principle in respect to your point #1 about the new quota which I believe was not observed so far during this discussion and this is a very important change.

In BGP based LxVPNs architecture when you provision and delete a VPN site or a VRF you are not required to touch configuration of any other node in the network other than your immediately adjacent PE.

Your quota violates this principle completely by requiring you to modify the <RD,src PE> value or even if the value remains the same to add such <RD,src PE> pair to the list on each remote PE when you add new VRF or new sites to existing VPNs.

Regards,
Robert

Hi All,


    The updated draft is the fruit of previous intense discussions, we have analyzed various possible situations. Let me explain some major concerns again:


1) About the quota:
   Actually, the quota is not exist in the original version, but we found there are some problems during the discussions in the mailing list. So, we add the quota to improve the drop strategies after the VPN Prefix ORF mechanism is triggered. We can't drop all the routes(from all sources) belong to the VPNs when the VRF limit is exceed because one of the rogue PE.
    The reason that quota is set for every PE is that in real network the number of customer routes in each VPN under different PEs may be different. So, the quota value should be set depend on the customer scale.
   For more information about quota, I think you can refer the discussion: https://mailarchive.ietf.org/arch/msg/idr/uoQO8vqSA82UCrfXppFjwNbMg1A/<https://urldefense.com/v3/__https:/mailarchive.ietf.org/arch/msg/idr/uoQO8vqSA82UCrfXppFjwNbMg1A/__;!!NEt6yMaO-gk!EHHc7Z2KZAwai4Vbbo3RcwpyVEKt0aRGlNx94SStnmvJq_PnsTFqscUCTPCI5MELs0rSQsTWJ8J1D-k$>
