1. VXLAN/EVPN fabric between core/dist (leaf/spine) devices, IPv4 routed/L3 point-to-point links between core/dist
2. Deploy dist switches in pairs, with access switches connected redundantly to two dist switches
3. Core devices are only used for connecting distribution switches, external connectivity, firewalls etc are all connected to dist switches (possibly dedicated border dist)
4. Each dist/core device has two loopbacks, one in global/main VRF used for EVPN peering ("infra loopback") and one loopback in a dedicated management VRF ("management loopback")
5. Core devices are only used for connecting distribution switches, external connectivity, firewalls etc are all connected to dist switches (possibly dedicated border dist)
6. Deploy dist switches in pairs, with access switches connected redundantly to two dist switches
7. Mature API for management and monitoring (Netconf, SNMP etc)
