Hi Yubao, Thanks for explaining, although I’m afraid we disagree on both things 😊 but that’s ok. Others can chime in as well. * If you receive an RT1 with ESI-1 and a route-target identifying BD1, the RT5 with ESI-1 can be resolved to the RT1, hence the traffic will use the IRB connected t

Hi Yubao, I realized I did not respond to this (my apologies), and you reflected the same questions in your slides about draft-wang-bess-evpn-distributed-bump-in-the-wire during the BESS session. I think it is okay if you want to describe a “distributed” bump-in-the-wire scenario, but I don’t u

Hi Jorge, Thank you for your email. I know that EVPN application will pick up one. But my question is how can you make sure that the exact one in your expectation will be picked out? Other scenarios just need to pick up one for all RT-2 routes that refers to that ESI, but the Bu

Hi Yubao, For GW-IP overlay indexes, until the PE does not receive at least one RT2 for the GW-IP, you can’t resolve the RT5. If you receive multiple for the same IP with the same key, it is bgp best path selection. If you receive multiple for the same IP, different key, the EVPN application pi
