Route reflectors for EVPN sit on the city spines so leaves need not mesh full EVPN iBGP. What design idea does that apply?
Select an answer to reveal the explanation.
Short Explanation
Put EVPN route reflectors on the spines (or dedicated boxes) and leaves peer upward instead of building a hairball mesh. That scales the overlay control plane. Reflection does not delete VTEPs or turn into an STP BPDU sprinkler.
Full Explanation
MP-BGP EVPN commonly uses route reflectors—often spines or dedicated RRs—so leaf VTEPs maintain fewer overlay sessions while still learning remote EVPN routes. That is a control-plane scaling pattern, not a ban on spine reflection, not a replacement for VXLAN data-plane VTEPs, and unrelated to flooding STP BPDUs.
