I wanted to confirm if Cisco is stopping its support for PBB-EVPN in favour of EVPN on ASR platform. If that is correct then what is the reason for it? From what I understand PBB-EVPN is more scalable than EVPN which makes it a better option for service providers and carriers. Why would then Cisco discontinue its support? I might very well be mistaken in my understanding so please let know if that is not the case.
