Hi Sasha, When a MAC-VRF use a type 1 RD, is it expected that the RD of the EVPN Instance has differnet RD on different PE? When a MAC-VRF use a type 2 RD, is it expected that the RD of the EVPN Instance has the same RD on different PE? In many deployment, whether the RD of the EVPN

Hi Yubao, Can you please clarify what you mean by “another way to construct A-D per ES route has been in sight”? From my POV using Type 1 RDs in all types of EVPN routes has multiple advantages – starting from the fact that it prevents RRs suppressing routes advertised by different PEs as part

Hi Sasha, Thanks for your helpful notes. There is only one method to determine the RD of A-D per ES routes in the original years of RFC7432, but now there are at least two methods to determine the RD of A-D per ES routes. If it is the only reason why RFC7432 restrict the RD of A-D per

Yubao, Please note that an EVPN PE that s attached to a MH ES, generally speaking, has to generate multiple per-ES A-D routes with the ESI of this MH ES in their NLRI. This happens because: * The set of these routes, in its entirety, must carry the Route Targets of all the EVI that are

Hi Jorge, I think the description in draft-rabadan-bess-evpn-inter-domain-opt-b is OK. But I don't know why the RD of AD per ES route is limited to type 1 RD. That's why I talk about this together with rfc7432bis. If the scenario from draft-rabadan-bess-evpn-inter-domain-opt-b has shown
