Hi Ali,

Compared to IEEE DRNI, what's the advantage of your solution? It's better to add a section in your draft  to describe the comparison.

Thanks

There is no plan to use DRNI for EVPN.

Subject: Questions about the draft of "A new Designated Forwarder Election for the EVPN"


Sorry to repost the email to make it more clear...



Hi Co-authors,
In all-active connection case, to avoid frame duplication and looping, only one exit point among multiple PEs corresponding to a ESI is allowed to egress BUM traffic from EVPN network to local access network . DF election algorithm is a candidated solution. To overcome some DF election drawbacks,this draft proposed a new algorithm to replace DF election algorithm.
IEEE802.1AX,DRNI specs also can meet EVPN active-active connection requirements. Do you have plan to use IEEE existing standard to solve the problem?
Thanks
weiguo
