Can MP BGP EVPN gets configured between Spine switches (in a leaf-spine non-aci based on nexus 9k) and external Nexus 9k switches ( which will be acting as a super spine )connecting different Campuses to the fabric?
I believe yes, but need a reference from Cisco.
if the answer is yes, do we need underlay between spine and super spine or we can have a flat MP BGP EVPN?
In that case I assume that spine switches in the fabric encapsulate the traffic coming from external, right? ( basically in the leaf-spine, all encapsulation and decapsulation gets done by Leaf or border leaf and spine does not do anything,however, if we have spine connected to super Spine, traffic entering into the fabric needs to be decapsulated at Spine?)
Thanks,
